- เผยแพร่เมื่อ 14 มิ.ย. 2022
- Welcome to part 4 of the total beginners course to FreeCAD 0.20. In this lesson we will learn basic skill of tracing reference images to create a simple part design model. We will be introducing the fundamentals of construction geometry in FreeCAD sketcher to reduce the amount of constraints needed. Learn about angle constraints and use of the arc tools. As an introduction to the Image workbench we will help teach the fundamentals of freeCAD understanding the basics but delivering via teaching you different workflows.

Got a bit lost in the beginning as it seems Image bench was depreciated after version 0.20.
In version .21.1+ you now need to go File -> Import, to select your image file and add it to the 3d workspace.
Double Click on the imported image in the left bar to access the Image Plane settings, this is where you can choose your plane.
To scale the image, use Calibrate to get the selector for the red line, as in the video.
Ahh... this is what I was looking for, cos I went to use the image workbench today. 👍
Thanks for this!
You have to right click on the image in the tree view -> select "calibrate" at the bottom -> use the red line to set the width -> hit ok
Thank you! I'm on 0.21.2 and was looking for this 👌
THANK YOU! I was trying to figure out what happened to the image workbench and this is the only place I've seen mentioned that it was depreciated.
The only downside to watching these videos is I'm now starting to question my design choices on previous parts I have modeled up on FreeCAD. Thanks for great pacing, no loud music and videos that actually implement the methods you talk about!
There's so many ways to get to the end goal. If you achieved your goal you have succeeded so haven't done anything wrong. Each way you learn something extra which is valuable. Questioning your previous route shows your really starting to understand the program. Thanks for coming along on the journey. No you won't get any loud music hear and I always try to use practical examples. If not I will follow up with one in another video. Unless I have a practical example then I can't remember it as I have no reasons why I need the information so my brain just gets rid of it.
Same here. Sometimes I got the impression of reinventing the wheel, lol
Without doubt, the best Freecad videos to be seen. This guy is an absolute Freecad NINJA 10/10
Thank you :)
I did it! It took me several minutes after your video to get this thing constrained and figure out why freecad wasn't closing the wire, but I finally got it!
Great to hear 😀👍. Remember being fully constrained is best practices but not essential.
If anyone also had a problem with setting up symmetry constraints to arcs - I have found another solution, which for me worked fine.
Draw a line between both ends of an arc. Select this new line and the respective construction geometry line (like with symmetry constraint) and add perpendicular constraint. Repeat for all three arcs. Select these three lines and add equal constraint. After that convert them to construction geometry.
CAD instruction for beginners showing how it SHOULD be done. Solid gold tutorial.
Center point for the side archs should be coincident with the center of the pipe.
Brilliant presentation and bravo for the pedagogy!
If you want to reduce the perspective distortion,
then take the photo from the farthest distance you can
with the maximum zoom.
That's is an awesome tip! Thanks for sharing.
For a flat part, you can use a flatbed scanner to get an image that is true to size.
@@roofoofighter I think one of the lessons was how to get the proper scale from photo. However, even if you were to import the image that way, you could still resize it to view in which case, you'd need to know how to set the proper scale so you can draw at any zoom level.
IMHO it is possible to shorten this workflow:
1. Draw a circle in the center using the "3 rim point" tool.
(This method automatically matches the circle to the image. We don;t have to guess its center.)
2. Construct three construction lines 120° apart, which pass through the center on BOTH sides.
(extending the line to the other side is useful to create the geometry on the other side)
3. Draw one corner first:
3a. Draw the small circle. Its center lies on the construction line.
3b. Trace the two straight lines on the part, and let them intersect at the construction line.
(The two straight lines form a "V" at the corner.)
4. Repeat step#3 for the other two corners.
5. Now we have three Vs at the three corners.
These 6 lines intersect at 6 places.
Create fillets at all these six places. Adjust the fillets to roughly match the part.
6. Add constraints to make the fillets symmetrical around the construction lines.
7. Add dimensions to fillets and circles to match the part.
Love your style. You take your time, and don't go wizzing around pressing buttons without explaining things. Gr8 stuff
Thank you 😊
Agree! I love his style too. Very well paced and explains every step!
Excellent tutorial!!! I've been going through your tutorials and am glued to my laptop. For CAD beginners such as me, this playlist is The Holy Grail. Work and learn surely helps in quicker grasping of important concepts. Can't thank you enough.
You're very welcome! It's been a great experience doing these videos. I knew the community was looking for something like this but I didn't realised how well excepted it would be. Thank you.
Helpful Timestamps:

Workflow:
IMAGE WORKBENCH - SKETCHER - PART DESIGN
2:53
Image to be sketched should be clear with preferably with a 90° topdown view and without shadows
3:19
New Document - START - IMAGE - CREATE IMAGE PLANE (creates a planar image in 3D space) - CHOOSE AN IMAGE FILE TO OPEN (image file preferably '.png' as it preserves transparency) - CHOOSE ORIENTATION (XY Plane)
4:18
For accurate dimensions, the image needs a scale reference from IRL,
SCALE IMAGE PLANE - DISTANCE (mm) (Set the reference measurement which allows for the rest of model to be as per scale) - SELECT FIRST POINT (choose between two points that represent the actual measurement of the original model
6:04
Verify the image scale by, MEASURE DISTANCE
6:44
COMBO VIEW - MODEL - UNNAMED - IMAGEPLANE (selected) - CREATE A SKETCH - (pop-up) SKETCH ATTACHMENT - select the method to attach this sketch to selected object - DON'T ATTACH - CHOOSE ORIENTATION (XY Plane
7:14
The image should be centrally aligned with the model canvas,
COMBO VIEW - MODEL - IMAGE PLANE (selected) - DATA (Tab) - PLACEMENT (nudge around with the axis until the image is relatively central)
8:27
For better visibility between the image plane and the canvas
IMAGE PLANE (selected) - VIEW - TRANSPARENCY (as needed)
9:41
CREATE A CIRCLE (Auto constraints activated, so as to centrally align it with the 00,00 coordinates) - drag out from the center point to the diameter required
13:15
For PCD of the flange holes, sketch straight lines from the 00,00 coordinate to the flange circles center, angle the two flange holes by selecting both the lines, bonding them with the CONSTRAIN ANGLE (fix the angle of a line or the angle between two lines) and set the degree of angle require
13:15
Make both the lines of equal length by selecting the. and clicking CONSTRAIN EQUAL
16:15
Add a length to the line between the centre point and the flange hole's center by selecting the line and clicking CONSTRAIN VERTICAL DISTANCE (Fix the vertical distance between two points or line ends) - INSERT VERTICAL LENGTHS
17:35
To only represent the sketch of the model, click SKETCH - SKETCH GEOMETRIES - TOGGLE CONSTRUCTION GEOMETRY, after selecting the lines that should not appear on the model
18:40
To create the rounded vertices of the flange click,
ARC - CENTER AND END POINT (center point of flange hole as reference, drag out the arc-circle to match the image boundary, click on the where the ARC should begin and end as two points that match the image
19:24
Make the ARC points symmetrical by selecting both then selecting the reference point to which they should align and click '>
Wow, thank you for taking your time and adding this index. Much appreciated.👍👍👍👍👍
Grazie, sei bravissimo, complimenti.
Just discovered this excellent series, have previously tried FreeCad trying to follow others but gave up ! Wish I have discovered this channel a couple of years ago. Well done and keep adding to the channel.
i must say that I'm picking up on this very fast, thanks to your simple explanations and breaking things down. i can't wait to move to the next video.
Great to hear you're progressing. And thank you for the feedback, it's always good to hear how people are finding the videos. Happy freecading
FYI for anyone who has an issue with your outer lines appearing a different color (light blue in my case) and not showing up in the 3D view (almost like they are invisible). I realized later on that the newly created lines were set to "Geometry Construction Mode" (as mentioned @ 17:16). This button is a global toggle instead of a one-time action (which MangoJelly mentioned to at 18:00, but I didn't realize I necessarily had to untoggle it in the moment). Just select all your outer lines and toggle the "Geometry Construction Mode", and your lines should come back to life! Using version 0.21.2.
This channel has to got to be one of the best ones I've found for learning freecad. I appreciate you! Thank you
Wow, thank you! It's been a pleasure to help everyone by doing these videos. There is a new feature coming soon to the channel so keep an eye out for that. I think it's going to help everyone even further.
One of the most useful Freecad videos that I have seen.
Thank you very much.
Great tutorial. Thanks for your efforts. I´m hooked on this series.
Just want to thank you for this vid. Referenced it a few times now. I dont work with images often, so I have sometimes forgotten how to do it, so youve been a great help! Tyvm
Glad your finding them useful 😊👍
Very nice, now I know how to make a gasket to be able to export to make my part.
Looking forward to the next lesson. Thank you!
Great fun to rebuild. Thank you :)
This was fun, easy and super cool. I actually did it. I feel like an engineer.
Nice to hear :) Welcome to the journey :) :)
Thanks. This was good and clear tutorial.
Thank you so much for such an amazing tutorial.
Mr. Jelly, It would be a real shame for folks to miss this lesson because they are using the newer version and did not see your answers below in the comments to your update video on Image import. When I look at the comments section it is default sorted on Top Comments not newest, once I resorted and got clued to the update video, I was able to complete the lesson. Perhaps you can add a note and reference in the show notes, as folks need to go there to get the link to the images anyway.
Just saying. PS, I have joined your Patreon group.
Thank you so much for pointing this out and sharing your experience. I thought I added it to the show notes but obviously not. I have now added and also added a popup comment in the video. Really appreciate the heads up and thank you for becoming a patreon :).
thank you sir...easy step by step tutorial..👍
I found the best way to draw the outline was to add circles and then lines with tangent constraints and then trim away the unwanted parts of the circle
My word Tony, I definitely second that. Plus, there is another sweet little bit that I haven't noticed mentioned yet, in this series: *construction geometry*! Allows you to draw lines that you can constrain on (such as those 120degree angles, together with the equidistant centers of circles and arcs) and those helper lines get ignored when padding into 3D, and therefore during the padding operation, FreeCAD doesn't bitch about the helper lines ruining the continuity of the surface ("wire is not closed"). Construction geometry is very useful for "scaffolding" constraints that you cannot stick directly onto the "production outline" geometry.
Ehh not sure if maybe I just didn't listen close enough. I'm watching this "on the back burner" at work and at home, often while doing some mundane manual chores.
To me as a hobbyist, after past experience with Sketchup and LibreCAD, today FreeCAD and parametric solid modeling is a shiny new mental toy. I love this, the meshed constraints set my mind racing. Thanks @MangoJelly for this tutorial series!
Your explanation and detail is perfect! Love this series
Thank you, glad your enjoying 😊
Great Work!
All the nuances of the design are explained very well. Thanks!
You are welcome! Glad it was if use.
These are super helpful mate, thanks for the time and effort
No problems, glad your enjoying.
Awesome, really explained in detail, thanks.
Thank you
One tip that I can share about the use of reference images. if you use a scanner and scan it in at 72 DPI. then it should have the right scale when you import it in freecad. but it can't hurt to check this is still true in later versions
Thanks for adding that, great to get more hints and tips from others as it really enriches the learning experience.
and thank you for doing the tutorial series, it's very well explained. back when I started it were mostly silent videos that did help but where at the same time confusing at times. so it's time now to learn some more about freecad after my (mostly) self thought work flow is running a bit to his limit with some more complex twisting shapes.@@MangoJellySolutions
really great videos that actually teach you things in a way that you can use them in your own projects! I love it.
Glad to hear, that's exactly what I was aiming for 😊😊😊😊 thank you
Really great tutorials. Thank you 👌
Thanks 😁👍
These are some fantastic tutorial videos, very precise, step by step instructions, clearly explained, and demonstrated.
My only issue is, occasionally, I can't seem to find certain options to select. Not sure if this is because I am currently running Ver. 0.21.2 and most of these tutorials are Ver. 0.20, or because I am on an iMac (M3, Sonoma 14.4.1 OS), or perhaps it's because I am a blind newbie. (Most likely a combination of the three)
Anyway, great videos, I really am learning a lot.
✌🏻from🇦🇺
Thank you for these excellent tutorials. At the end I got the impression that the last constraints missing were the tangents between the bottom right arc and its adjacent lines. Maybe if you had those, the length of the lines would be consequence of all the rest being constrained.
Great tutorial! Thank you!
Glad you enjoyed 👍😁
I absolutely like and enjoy your videos.. you take the time to explain the basics before moving on...Thanks so much. (I am a beginner but not for long as I follow your vids...)
Thank you so much for sharing your kind comments. I am blown away with how supportive the community has been with these videos. So glad to see your improving 😊
Thanks! Your series made me appreciate how much better the UX of FreeCAD is compared to Fusion which i have been trying to learn
Great to hear! Thank you so much for the donation :)
The Image workbench is removed from 0.21. I used Import to import the image, unfortunately the Image Scaling tool is gone as well. I just copied your dimensions from the video, but how does one do this procedure in 0.21? Thank you in advance and also thank you for these videos!
Check out the following video. I created this a while back to help with the new way that this is done in 0.21 th-cam.com/video/WhxDAgskcHA/w-d-xo.html
@@MangoJellySolutionsthanks, will do! I also found the solution, you just double-click on the image entry in the Combo View and on the following requester that opens you select 'Calibrate'. From there you can measure and input known dimensions.
this guy deserves more credit
Thank you so much 😊😊😊
i love how you intentionally got wrong so you could show how to correct it!. you're a great teacher, have a nice day!
Thank you so much, part of the learning is to know how to get out of a problematic situation so I tried to include whenever I can.
Thank you very much was exactly the info i needed Thumbs up
Great to hear :)
Finding you videos much easier to follow than others I tried. I did have trouble towards the end setting symmetrical constraint on the corner arcs. It would mark them as 2 over-constraints. Rotating the sketch slightly would remove one over-constraint and rotating it back would put it back again. It would then break the sketch with some points no longer coincident. I was about to give up but saw @moonlyr's comment about putting a chord across the arcs, constraining it as perpendicular, then marking the chords as construction geometry. That worked a treat. Not sure what caused this. I also can't find how to get circle centre marks, crosshairs. like you have. To be honest I am struggling to get all the dimensions to format consistently, number of decimal places, units etc. Thanks for efforts I will continue to watch and learn.
needed : links to your image files - so that we can do the same same "homework" step b, y step while you are presenting the work. thereby we can duplicate your steps to learn better.
Hi, thanks for the comment, the link to the image is in the video description. Follow the link and you will need to right click and save as.
I've been watching several videos in English ( because in Spanish they're empty and they're made for experts that already work speed fast) and ...... since the workflow and detailed instructions with patience? your channel is my preferred . Also have to congratulate you for being the most viewed tutorial on the web, and......there's a great reason for that. also I'm also subscribed already.
Wow, thank you for such kind words. It's great to have you on the journey enjoying these videos and there's plenty more to come.
very good video, very good techniqs
I was curious to see how you would go about reproducing the uniformity of these curves (the outline).
So I'm not surprised to find that with you as a teacher, everything that may seem difficult, suddenly becomes easy to accomplish.
Thanks again.
Thank you for such kind words 😊😊
Great, Fun, Educational - You could also teach other teachers about learning flow, getting the point across, making the student understand.
Thank you, and thank you for comments on my teaching style. I was studying to be a teacher but that was many years ago, the company I was with basically went bust at the time I sat my exams so never got the results and lost a lot of money and all my course work. This channel is part of that dream for me 😁
I’ve recently starting learning free cad. I already knew how to do 2d drafting from working on cnc machines so, it’s come to me easier than I thought but I am enjoying going through your videos, even the simple ones because I’ve noticed you have lots of different little tricks I would never have even thought of. Like the geometry construction, that’s going to come to some use for me. Thank you for taking the time to make these videos, they are a massive help for me and easy to follow.
Thank you so much for the feedback always appreciated, and the kind words. It's great to get comments from people who have worked and experienced in the industry as I can get an idea of what everyone likes across the board. Glad it's all helping. 😊
Thank you for these tutorials. I have about 600 hours experience using OnShape and I am moving to FreeCad. These videos have been extremely helpful. Thank you. I respect the pace you are presenting the tools and techniques as well. You give them something new then let them repeat it a few times to help it sink in. I would like to see a follow up video that shows how to accomplish the same sketch but using Mirrors and Symmetry instead of repeating the same tasks to create the rest of the sketch. Just an idea but once I learned that in OnShape my design time was cut by about a third. Since the FreeCad "Symmetry" tool doesn't automatically add the Symmetric Constraint to the Points it takes a bit longer but it is still a faster approach that requires less brain power.
EDIT: I see the next video is using polar pattern. I like that. However, I still think that using Symmetric tools in the Sketch is also worth knowing. (My opinion.) Great job. Love your work.
Thanks for the feedback, I always appreciate the time taken by viewers to explain how they are finding the videos and what they like and don't, it's all taken on board. Great idea about the mirror, I do have tutorials with mirroring in my understanding freecad series but it's something that I should include in this series. Thank you so much for your time and the constructive comments.
Great tutorial style. Thank you for your efforts. I am excited about your next video.
Pretty slick
Thank you for this nice tutorial. Although I don't want to trace a photo right now, it made me understand some things about the constraints. By the way, nice trick to add a real measurement as a scale, which is actually what those measurement tools for the SmartPhones do.
Glad it was helpful! Always good to learn something from the video even if your not going to use it just yet. 😊 It's worth experimenting with different ways to constrain this one especially with utilising the construction geometry.
Thankyou dear teacher i must try to make drawing as you teach us.
thank you!!!
In version 0.21 and up the option "Avoid redundant auto constraints" is hidden in the constraints box on the right top in the settings dropdown.
I am very tempted to reshoot these earlier videos for 0.21. I change over to 0.21 part way through the course. Thanks for adding that information. Always welcome.
Great series! I had quite a bit of trouble with the final set of constraints (took me a few tries). I am running version 0.21 and a few things seemed a little different as far as constraints go - maybe that threw me. Otherwise I did make it through and actually printed the flange. good stuff!
Great to hear 😊😊👍👍
These videos have proven to be a game changer for me. Great narrative and a pace that even I can follow. I can't access the shape on the patreon page to enable me to work through this one. Am I missing something obvious?
Glad your enjoying the videos. Regarding the image you should be able to right click and save as on the image from this address www.patreon.com/posts/beginners-lesson-67672255
👍Great job so far. I'll have to do some binge-watching though.😂
Lol, thank you. Think you need to get some popcorn in.
Thank you for these tutorials, These are very clear and definitly helpful.
The image transparency did not work for me in version .20, I tried in version .19 and it works.
Hi, wasn't working for me either, but I found you can use the Shape Color control to apply a different color. Which worked well
Once again thank you so much for your hard work. I'm beginning to understand the underlying logic of the software. This is a far more accurate way of designing. I was watching a youtuber doing almost exactly the same as this tutorial. He was replicating a broken plate for a laser engraver in Fusion360 and while his process was quicker it was obvious that he wasn't as accurate as this lesson. He had to iterate a number of times because of hole placement. It seems that Freecad forces you to think cleanly. As a treat to myself I printed out this gasket in TPU. I can state unequivocally your channel is the best there is for training Freecad. I am both terrified and looking forward to Episode 4.
BTW just a tiny thing, maybe because the update to 0.20.2 but right at the end when I created a body in Part Design the sketch jumped into the correct place automatically. No dragging needed.
Thanks for taking the time to reply. Fusion 360 is quite forgiving it will allow you to carry on when if there is an error but, as you say, freecad forces you to do it correctly, a bit like a old school teacher waiting for you to do something wrong ready to hit you with a ruler lol. Glad your enjoying the videos and finding them useful.
Thank you for your very informative tutorials. I am a novice with FreeCAD and they help me a lot to get to know how to use it. I just wonder if a polyline for the outside edge wouldn't have been faster? Having said that I haven't tried to do that yet.
Glad it was helpful! Yes you can use the polyline tools and use the M key to switch between line and arc modes to make the workflow quicker. This can be a little tricky when your first coming to freecad but it's a great tool to get to grips with as it will save a lot of time.
This was great lesson. Can you help me find image workbench? I have ver 0.21.0 I looked in ad on manger and don't see it
Glad you enjoyed. So the image workbench has been removed in newer versions and bite the import option on file takes care of it all. Check out this video which explains how th-cam.com/video/WhxDAgskcHA/w-d-xo.html
Thank you
For those who wondering where the avoid redundant and autoconstraints option is in FreeCAD 0.21.2 they moved it in to Combo view (Sketch chosen) under property -> view.
Thank you for highlighting this for everyone. I appreciate that. I am very tempted to redo this video for the new version.
@@MangoJellySolutions let us know if you do with notifications, maybe there's more to change for the new +.21 version in the following vids on the playlist?
Awesome tutorial !! I recently downaloaded the newest version of freecad(version 0.21.0), the Image option is removed and I couldn't find the option to scale image and had to scale it manually, is there still an option to scale image as shown in the video?
Ah yes, so you will need to have a look at this video, it explains the way images are imported now. th-cam.com/video/WhxDAgskcHA/w-d-xo.html. Glad you enjoyed the video.
@@MangoJellySolutions Put this in the description. Annotate the video at the relevant part. Thank You.
Hi! I’m loving your tutorials but I’m using V21 now and they’ve removed the Image Tools. I’ve figured out how to import the image but I’m stuck on how to Scale Image Plane in this newer version. Any advice would be appreciated! Thank you!
Hi, glad your enjoying. Take a look at th-cam.com/video/WhxDAgskcHA/w-d-xo.html which shows how to import and scale the image in 0.21
Thank you!
Amazing tutorial. I am so glad I found it.
But I am experiencing some glitches with Freecad 0.20.2. Whenever I try to use the measuring tool it, it would crush the app. Tried it in different workbenches with simple object. It's all the same. Any thoughts?
Do you have any idea why my screen goes completely black after trying to drop the sketch into the body? I've never had that happen before on any other program. The process itself works but it's like I have to navigate while blind, but in this case it's a black screen.
21:40, when applying the symmetric constraint to the second arc about the construction geometry, the symmetric constraint is flagged as redundant. I'm unsure how to fix it. FreeCAD 0.21.0
Further operations on the sketch show the message "Recompute Failed!"
Thanks!
Thank you so much 😁😁👍👍👍👍👍
I am trying to learn this software, but it appears this is an older version, the Image Toolbox is no longer available. Can you point me to a more updated training video to import a photo to build from it?
Freecad in later versions have drooped the image workbench and you can use the import instead but there are differences in scaling. I put together a video to cover this th-cam.com/video/WhxDAgskcHA/w-d-xo.html
sorry for the translation made by google from PT-BR ->Ing
Wonderful channel with a lot of didactics and perfection in the sequence of showing the possible mistakes and then correcting them during the class... Congratulations.
but in this video I noticed a single ERROR.
I think that when fixing the radius of 180 in the rounding of the middle arc there was a design error.... I believe that the center of this radius must be the same as the central hole.
I believe that this can be proved by maintaining the equality of the straight tangent arcs and segments...
this measurement ends up coming out naturally moving the center of the arc and adjusting the image.... I believe it should hit the center of the larger hole
Thank you so much! I have tried twice but somewhere It lost constrains? All the lines did not become green but it still allowed me to add pad and export to stl file! More practice needed I think. Also as someone mentioned. I am using 0.21 and did not have image feature. But You have explained in other video. It looks so simple to make but difficult to create 3D file! Thanks you .
You don't have to have a fully constrained sketch, it's just best practices. You will find it's one little constraint that you are missing. Yep, 3D is hard but once you get the basics down it will get easier :) Glad you enjoyed
Great tutorial’s but I think that is an exhaust flange gasket.
newbie here! was wondering what the workflow should be for creating a cylinder construction consisting of two different sized cylinders connected with one having an extrusion with a square end to it. Its for a drill bit at one end and a connection to a drill at the other end, Its a specialised tool hence the requirement for an adapter. Not sure if im using part design or sketcher and the workflow.?
By the sounds of it this is actually quite simple. Look at the part design and use a loft between the two sketches profiles. One of a circle and ove of a square.
THX for your videos. I have a trouble to open picture on FreeCad 021.1 . I try to add a tool but I can not find this "Image" tools.
I found it in your recent video , it must be done trough: file-->import
I have a video that will help you as the image workbench has been removed in 0.21 and the is a different method via import. th-cam.com/video/WhxDAgskcHA/w-d-xo.html
Finding my way around this series of videos on TH-cam is a real challenge. Can you post some kind of list of links to the series?????
No problems, in the description you should find a playlist which has all the videos listed in order. If the link isn't there then it can be found at th-cam.com/play/PLWuyJLVUNtc0UszswD0oD5q4VeWTrK7JC.html
I am going to go through and check all descriptions to make sure the link is available and also add to the video as a end of video link.
@@MangoJellySolutions Wow, that was quick. Thanks.
@@MangoJellySolutions would you ever consider adding a dissection of each video like time stamps of what sections go over what?
a suggestion for your consideration, for the next instruction vids, is to have a circle for your cursor, why? when you click on a function, the circle would direct my attention to the item your describing.
Thank you for that. Because of your comment I have now on my other channel for blender 3d have changed the cursor as working in windows. Much easier to follow especially on dark theme. I need to find the equivalent in ubuntu. This has just reminded me to do that.
Great video! Just curious, how would I define a constraint of a "rounded square" if I only know the max width between two sides?
You can use the points. Find a red point at the end or beginning of say the left edge and the same on the right and make a length constraint. Your probably clicking on the line and adding a length but you can also do this between two points.
@@MangoJellySolutions Thanks! Do you offer any instructor led virtual courses? Something interactive where you train and shadow beginners to use FreeCAD to model objects? 😎👍🏼
07:34 [noob issue] In version 0.21.1 it seems not possible to move the image until the sketch is closed, but then the "crosshair" disappear.
[edit] Ok, found a workaround - In the sketch, draw two lines on the axis and then close. Those lines will be visible also when moving the image.
If your using 0.21 then you will be wondering where the image workbench is. Take a look at this video (Where has the Image Workbench gone in 0.21) and then you can resume the tutorial using the new way of referencing an image. Hope that helps. th-cam.com/video/WhxDAgskcHA/w-d-xo.html
Sir, i dont know whats going wrong,
I tried following you step by step
But at 22:17 it gets overconstraint
I dont know what to do,
Even i dont have “avoid auto redundant constraints” option there.
Version 0.21.0
Symmetry constraint on that 2nd arc
Causing over constraints
What to do?
sorry for the translation made by google from PT-BR ->Ing
Wonderful channel with a lot of didactics and perfection in the sequence of showing the possible mistakes and then correcting them during the class... Congratulations.
but in this video I noticed a single ERROR.
I think that when fixing the radius of 180 in the rounding of the middle arc there was a design error.... I believe that the center of this radius must be the same as the central hole.
I believe that this can be proved by maintaining the equality of the straight tangent arcs and segments...
this measurement ends up coming out naturally moving the center of the arc and adjusting the image.... I believe it should hit the center of the larger hole
@@abidhasanonib9032 in the sketcher when you are editing a sketch on the left hand side panel you will see a little drop down. The options for avoid redundant constraints has moved into that drop down for 0.21. That should help you fix the issue
"Take a look at this video and then you can resume the tutorial using the new way of referencing an image"what vidoe are you talking about, because the one Im watching above shows the image workbench. Where did freecad move the image workbench in 0.21? Did you forget to link the new video? Im so confused.
20:42 - Where are those Edit Controls (Avoid redundant auto-controls) in FreeCAD 21.0? I can see only Solver messages, Constraints & Elements. Thank you!
They have moved to a small drop down on the left hand side in the sketcher. So before they were all visible now you have to drop down the selector. That along with the image workbench moving I think am going to have to redo this video for 21
@@MangoJellySolutions not needed imo. I personally understood it well. :)
Next 5.2 were a bit more difficult (due to different measurements I had :/ (also, in 5.2, adding initial sketch to padded face side - for some strange reason did not work well for me in 21. But I have managed somehow. Getting there slowly. All is nicely logical.)
Thank you very much this great tutorial videos.
👍👏
Hi.. grrrrrrrrrreat vid as always. Question. Is it possible too use freecad but having the files saved in my onedrive (cloud storage)?
I don't know, I remember with Google drive you used to be able to download another program that allows you to set it up so it acted like a shared drive. But that was a couple of years back.
@@MangoJellySolutions i think that this subject could make a very good video since nobody seems to have donne any tutorial on this. Would like to donate to the chanel and also i read you message the other day. I may have two opportunities for you.
Yes. It is fairly easy to setup as well. Make sure you have the OneDrive app running in windows and that you are logged in. Then simply save your FreeCad files into the OneDrive Folder on your computer. The app will sync everything to the cloud drive in the background.
@21:52 when I tried this for the vertical line, I used the vertical axis (not the vertical construction line) as the reference and the symmetrical constraint was redundant , after deleting a constraint it worked, but for the other two arcs when I try to use the symmetric constraint with the other two construction lines as reference it pulls out the same redundant constrain error and asks me to delete the symmetric constraint....
At about 30:40 where you are looking for what isn't constrained, could you expand upon that please? You mention that these two have an equality but these don't but I was having trouble follwing
Hello, your video is great. I have a small problem; the image workshop is not in my list. How can I add it to this list? I'm running Windows 10. I'm new to FREECAD and I'm a novice. I am french. Thank you
Sorry for the delay, playing catch up. This video here will help you as the image workbench has been removed from 0.22 th-cam.com/video/WhxDAgskcHA/w-d-xo.html
Désolé pour le temps qu'il a fallu pour vous répondre. Je rattrape les messages. Le workbench a été supprimé dans la version 0.21 et remplacé via une importation standard. C'est quelque peu différent et j'ai créé une vidéo ici. th-cam.com/video/WhxDAgskcHA/w-d-xo.html
I didnt understand the part with orange highlight and constrains and my options at Part Design work bench are not active, I can embody my outline of curves and lines though it is all green.
Also, when I press Sketch the lines do not become yellow though the Option Sketch itself is highlighted yellow.
Then I found this orange - after clicking on those restrains and now I have "Error build geometry(10): Both points are equal" everywhere.
Print it and throw it down on the original. That would be pretty cool
Now that's a good idea 👍👍👍
This file is incompletable freecad 021.2. I spent 2 days trying to, I get about 3/4 the way through then things won't constrain. I even have a near perfect flange picture. this needs to be redone in 0.21.2. I love the series. I wonder how many others videos don't work right in 0.21+
At the 22:35 mark when I add the tangent constraint it gets overconstraint with 7,21,22 around the symmetrical constraint. Why does it do that after following everything step by step ?
I have a newer version. I watched the video that showed how to import image. I cant figure out how to center the object on the x-y intercept. The way it is done in the video does not seem to exist in my newer version. Any tips? version 0.21.2
Add new sketch, exit out of sketch double click on image, then a window pops up but no axis shows. Guess how many mm adjustment needed and click back and forth between sketch and image until it is centered. This is the best I could come up with.
Did you use tangent constraints on the bottom right arc?? I didn't see it.
The target constraint may of kicked in with automatic substitute. But yes they would be tangent
Any chance you could do a newer tutorial since the image plane position stuff is all different in 0.21.2 ?
Sorry for the late reply. I have a video for the new way the images are imported Here is the link. th-cam.com/video/WhxDAgskcHA/w-d-xo.html I am looking at a refresh of some of these videos.
I am using mac so in Add on manager I searched for Image to install image workbench but I don't seem to find it. Search for image filters out to Render workbench which I install but still image workbench I couldn't see in the drop down menu of workbenches.
okay it has been removed found your video explaining on it. :)
In the later versions of freecad the workbench has been removed and there is a new way of importing and dealing with reference images. I have created a video to help you th-cam.com/video/WhxDAgskcHA/w-d-xo.html
22:30 - I have followed the instructions at least 8 times and every time i apply the Tangent constraint I get "Over-Constrained: (6,21,22)", 6 and 21 both are regarding the constraints applied to the bottom right circle, i have tried redoing this 8 times and even tried deleting those constraints which then everything goes out of whack, I'm not sure if its just something I'm missing or something which is different in version 0.21.1, any guidance would be helpful TIA
Same im getting wrong arch radiuses and over tangents, and everytime i add tan constraints everything gets messed up. maybe its the version differences idk.
