- เผยแพร่เมื่อ 21 มิ.ย. 2022
- Welcome to the total beginners course to FreeCAD 0.20. This is a two part lesson where will practice our tracing skill in the form of a mini project. Using reference photos we will create a more complex part which will consist of repeating features that we will utilise symmetry tool to ease construction in both FreeCAD sketcher and Part Design workbench.
This project work will help teach the fundamentals of freeCAD understanding the basics but delivering via teaching you different workflows.

Wow. I am unreasonably lucky to be learning FreeCAD AFTER these videos were created. Your lessons are incredibly useful. Thank you for the time and work you put into this!
You're very welcome! Glad there helping with the steep learning curve to make that learning a little bit more easier.
The pad button is the most satisfying button in free cad
I prefer boolean operations
Luckily I followed this video, and I can see that you don't leave out any important details!
I was desperate because sometimes I couldn't finish a piece of work, now I know what I did wrong and I can get back to work with new courage
thanks
Started learning ins and outs of FreeCAD, inspired by this channel. My end goal is to design unique canoe/tiny boats and eventually build them.
Great to hear, lofts with cross section profiles will be your friend when coming to boat making
Patience and generosity. There are no words to thank your work.
Greetings and thank you
Thank you 👍😊
Thanks! I've greatly enjoyed this series and learned a lot.
Thank you so much, glad your enjoying 😊👍
I gotta confess to doing a 3d print of your gasket.(A guilty pleasure!)😜
Your previous video on sketch tracing helped me create a Latchkum that I uploaded to grabcad. Next is to create the inner workings so it can be use in a real game of Latchkum but less dramatic. Thanks for these videos.
I'm using these videos in two ways: First, I try to create the finished drawing myself, just working things out. Next, I go back and follow along as closely as possible to how you're doing it. I believe I'm learning quite a bit by doing it both ways. I'm enjoying these tutorials. Getting closer to visiting your Patreon page.
Great to hear your learning style. Just remember that you may end up doing it in a different way to myself but please don't think what your doing is wrong. It may differ to mine but there is a hundred and one ways to create the same model. Great to hear that your learning
True: If just watch a tutorial, it looks so easy and intuitive that we do not feel the need to practice the lesson. But if we are asked to do it on our own, the mind goes blank!
So practice is the key.
While we are doing it, we also come across new doubts and new possibilities.
If we watch these tutorials passively, it will never happen!
These lessons are invaluable and I certainly plan to start supporting the channel. Thank you so much for your efforts; your approach to teaching is perfectly suited to my learning style.
Thank you for such kind comments and I'm pleased that you're enjoying these teachings. It's great to have such a supportive community.
Version 0.21.1 got rid of the Image Workbench, the new way to add an image to the XY plane is File>Import>Select your file>Open. Once it's imported you select the image in the tree and under tasks you can change the plane, etc.
I haven't, however, been able to figure out how to scale the image.
It takes some time, but you can use the ruler tool to measure across the image, resize the image, delete the measurement, re-measure, etc until you can get pretty close to the size you are looking for.
Thanks for adding that. I am trying to add a sticky comment to all the videos that have tracing but it keeps getting removed. It may be because of the video link. If you double click the image in the treeview you will see a calibrate so you can scale the image. th-cam.com/video/WhxDAgskcHA/w-d-xo.html
In the tree view of you double click the image you will see a number of tools within a panel. You will see the scaling told within. Hope that helps. Also I have done a video on it th-cam.com/video/WhxDAgskcHA/w-d-xo.html
Can´t hit like often enough! thank you for your work!
Thank you, Glad you enjoy it!
That moment of relief when you find the 'Constrain Tangent' after you get to 18:00 and you still have 2DoF.
I was obviously dicking around with the image too much trying to get it perfectly aligned when my sketch disappeared. I was at about 12 minutes into the video so I tried to delete the sketch but Freecad was misbehaving. So, I dumped the entire project reloaded Freecad and started again. This time I didn't worry so much as to alignment but focused on the constraints. Got the all green in the sketch and moved on. I loved this video, there was a real sense of accomplishment getting the polar pattern at the end. As usual a brilliant tutorial perfectly paced. Thank you so much.
Loving this some really powerful techniques 😀
Massively valuable!
Thanks for these videos. I had been using DesignSpark Mechanical until a week ago. I liked using DesignSpark but, when I last tried to use it, it locked me out of all of my models - it demanded that I update my account and download DesignSpark 6. Although this wasn't too difficult, I realised that DesignSpark could terminate my account at any time (or implement a paywall) and I would lose access to all of my models. It makes much more sense for me to use FreeCAD which will always be free since it's open source.
Your videos are really useful. I think I have a much greater understanding of FreeCAD after watching the first 5 videos. I was a little wary of using FreeCAD since everyone says that it's difficult, but I understand everything I have seen so far.
I'll watch the other videos in the playlist!
Really good job teaching this, thank you.
Thank you very much for your work. I enjoyed learning very much so far. And I learned a lot especially using FreeCAD with help of your videos. I had technical drawing back in university, but that was some time ago 🤪. I like also the approach of using photos vey much as I think this is very useful when you want to modify an existing part to your liking and later maybe print it on a 3D printer.
Great to hear you enjoy videos. The ability of freecad to add photos and scale then to a known scale is a great tool to have. I am not sure if I covered it in that video but a little tip is you can change the transparency of the image from freecad by clicking on it and going to the View tab. This makes life a lot easier when sketching with lighter backgrounds. I did the same at school learnt technical drawing and product design which got me into learning 3D from books and loved every minute of it. Great to have you on board and hope these videos and all the new stuff that's coming up helps you on your journey.
@@MangoJellySolutions yes, you covered the change of transparency and I agree, it's very handy.
Basically I started learning 3D CAD because I bought a 3D printer (well, currently waiting for arrival 🙂) and I want to create my own stuff and/or replace broken parts at home 😀
Thank you😊😊😊
I am not gonna lie, I tried avoiding watching your videos because they're so damn long but there is a reason they're long, because they're thorough. All the other shorter tutorials I've watched ended up skipping a lot of things or only showing one workflow. I would have saved myself a lot of time and heartache if I had just watched these to begin with
I totally appreciate your feedback and understand your point. Some people just want the top level information and others want to take their time to get a fuller understanding. I did try at one point to create TLDR videos but they seemed to become to confusing and raised questions that a longer video would cover. CAD is a difficult subject to teach without going into the detail .
@@MangoJellySolutions Lol I assure you it's not a criticism, I've been making my way through these videos and I am definitely now having to stop and go back to go over things, I'd much rather things be too detailed than not detailed enough, my ADHD on the other hand doesn't appreciate the detail as much :P
Thanks!
Thank you so much :) :)
¡Gracias!
Thank you so much 😊😊😊👍👍👍👍👍
Thanks
Oh wow!! Thank you so much for your generosity :) :) :)
were engineers in different domains.. need to marry them up more is my vision, and being able to "envisage" it kinda makes it more understandable..
can you please explain more in depth how to read the DoF (degree of freedom) when you click on the number and they auto select, and how to fix them. i get them and dont know what to do with the information given by the application. great videos by the way
Yes no problems. If you had a single line without any constraints it will have 4 degrees of freedom. Clicking dof will highlight both points. One point can move on the x and y so 2 degrees. The other can do the same. Equalling 4 degrees. If you add a horizontal constraint you lock the points to be in line with the edge that connects them. So you have removed 1 degree of freedom. Point 1 can move in the x direction, but moving it in y will keep the two points in line so point 2 moves at the same time. So you now have 3 degrees. Clicking dof will still highlight the two point as they can move. Clicking on point 1 and locking it to the center point of the sketch now results in 1 degree as point 2 can only move along the x axis. Clicking dof now will only highlight point 2. Remember that being fully constrained is recommended but not necessary. Glad your enjoying the videos 😊
i love this product. puzzled that its free. Can anyone help me?? I'm having trouble with constraints an arc to a curve in freecad 21.2.. the project goes green, when i can validate Sketch and click highlight troublesome vertices. Zoom in and i see the tangent doesn't quite join. in exhausted trying to crack this ,,, HELP
Your model looks very easily but very tricky
Great vid as usual!, thanks..FYI I was having trouble with the "Trim Edge" tool to replicate your action in 19:25 as it was not deleting the edge. Looked it up on the freecad forum (Great resource for Troubleshooting) and found that I had the "Grid Snap" option checked; it worked after I unchecked it.
Thanks for sharing that information!
This is not obvious at all.
BTW, @MangoJellySolutions this is a perfect candidate for a "FreeCAD tips" short. 🙂
muito bom
Your lessons are great however, I am using Freecad 0.21.1 and there is no image workbench on this new updated version. Is there a walk around.
So it has been removed and it is now on the import but works in a slightly different way. I have created a video to explain how the new features works, I hope it helps. Here is the link th-cam.com/video/WhxDAgskcHA/w-d-xo.html. Glad your enjoying the videos
Hello MangoJelly,
I wonder if I can have your help about this lecture: FreeCAD 0.20 For Beginners | 5.1 |
At the time 18:41 to 18:50, in your video, there is orange alarm (the entire screen became orange). However, in my side, there is no orange. Seems good. In my area of 'Solver messages', it shows: 7 DoF(s). I clicked it and four points of the two lines became green. Now, what should I do?
Thanks for your attention.
Best regards!
Youfang
If you want a fully constrained sketch then it sounds like you have one of those highlighted geometry not connected. Pull some of the geometry and see what moves and use control Z to undo. From there you can constrain those geometries down. Hope that helps
Found this channel few hours ago and seem pretty useful.
Im Blender artist over eight years and seems like some kind od mechanical conponent modeling is way more easier to do in FreeCAD using sketcher.
But for more organic shapes sketcher is nightmate. Is there way how to get desired shape without sketcher?
Curves are not super intuitive as well.
Is there way similar to subsurfacw modeling to get desired shapes? I know there is somethink like this in Fusion360, but can't find anything like this in FreeCAD.
Also I would like to see your way how to create sibmarone, airplane or that kind of models woth smooth shapes.
Thanks for your work. I like the way you teaching. I finally deside to seriously learn FeeCAD.
I know exactly what you mean about organic shapes. I have been involved in a project with one of my Patreons where we are creating an ergonomic grip. I have been using the Curves workbench and I have to say it's been a challenge to get the grip shaped. It requires palm and thumb swells that are moulded to the users hand. I have been using a loft through a series of freehand curves and getting the lateral shape using the mixed curve of the curves workbench. Lofts are your friend when you come to these kind of objects. Thanks for the comments, I have a project in mind that involves a submarine, I have a flooded quarry where I live and I want to build a remote control submarine to explor it and then thinking about building one in freecad then rigging it with the necessary mechanics and electronics, again lofts would be used for this kind of shape. Looks like I need to make some videos 😁
@@MangoJellySolutions Exactly, These shapes are hard to create in FreeCAD. Anyway, looking forward for upcoming videos
FreeCad can't seem to distinguish between .JPG and .jpg files. .JPG does not appear properly. Could not change file extension by replacing .JPG with .jpg. Had to export .jpg again from GIMP 2. Great videos so far! Not too fast and not too slow for me!
Glad you enjoyed the video. And thank you for the feedback. Interesting regarding the jpeg issue. I will have a look and report to the Developers.
this is such a great series. Are you against updating / refreshing to use the new 0.21.1 image import/scaling/transforming approach? It seems very different between the new version and the 0.20 and as a beginner this is the part I really struggle - especially as its the first thing to figure out in these exercises.
Hi, glad your enjoying the series. In regards to the new image scalling and redoing the series. There wasn't much of a shift feature wise (except for the image workbench) to warrant a full redo but as 0.22 is around the corner (which is a game changer) I have a lot of work redoing the whole series ahead and already planning (I have a video that I am releasing soon to show the new features of. 22). I have a video regarding the image workbench changes and trying to find all the videos where I use the image workbench so I can add the reference video th-cam.com/video/WhxDAgskcHA/w-d-xo.html
Hi friend. I can only create patterns on the Part Design? Can't I do patterns on the Sketcher?
Why not just use the perpendicular constraint when defining the angle?
Trying to follow along only to find there is no image workbench in 0.21.1. am i missing something?
No don't worry your not doing anything wrong, so in 0.21 they have removed the image workbench and you are now able to this is with a straight import. When you import the image it comes into the treeview. Double click on the image in the treeview and you will see a panel with similar tools pop up. I made a video of this to help guide through the changes. th-cam.com/video/WhxDAgskcHA/w-d-xo.html
I really wish you had show how to fix lines that are not connected. I come across these points that are not connected and it's almost impossible to find anywhere to show how to fix it. I haven't yet watched the entire series, but it's such a common issue. It would be great to see it get fixed earlier in the course.
When lines are not connected it means that you haven't constrained geometry together within a sketch correctly. And left them open. This is normally none by say clicking close to rather than on the end points when laying down connecting geometry. There is a tool in the sketcher called validate sketch which can highlight these troublesome areas. Thank you for the suggestion I am not sure if I have created a video but I am thinking of doing one which details how to deal with a number of errors that could occur.
@@MangoJellySolutions I'm really just started learning and I couldn't have gotten anywhere without your videos. For that I thank you. There's still much for me to learn, so will continue through your course.
Funny thing. I installed FreeCAD almost 2 years ago and had open it up only once before finding your tutorials. lol.
I really enjoy your tutorials. IMO the best out there. FYI, I can't find the image to download via the link provided. Very weird and unfortunate since it would be nice to have in order to follow along.
Figured it out, each image has to be selected then 'saved'. There's no 'download' link. Looking forward to completing this video. Excuse my ignorance.
No problems but you have highlighted the problem that some people are having. I was just moving them to my blog at mangojellysolutions.blogspot.com/2022/09/reference-images-for-beginners-freecad.html but now realise why some people are having problems. I will add that instruction to the page. Thanks for letting me know.
@@MangoJellySolutions Thanks so much for the quick reply. What I really appreciate in your videos is the fact that you show examples of what 'not to do' and what happens when you do. Having watched many hours of tuts on using FC and still have questions. Hopefully, I'll find the answers as I finish viewing this series. Your efforts in producing these videos in such detail are very much appreciated by this viewer.
Just wondering: At 3:55, we change the position of the image manually. But it requires a good judgment about where the center is. That is error-prone.
Instead, can we snap it accurately?
For example, I can draw a three-point circle that matches the tubular part fairly accurately. FC automatically creates the center of this circle. If I can constrain this center point of the circle to the origin, and make the image move along with the circle, I can achieve the centering perfectly.
Is that possible?
Good question and I am wondering if the techniques of position in this video will work with images. I have never tried selecting the image in the draft workbench and using the move and snapping tools. It's worth a try and if it works then it may be the answer th-cam.com/video/GG0OB7taJUw/w-d-xo.html
@@MangoJellySolutions I posted this question at the forum, and got a solution (one user even posted a macro for that!).
I had shared that information here, but TH-cam holds such comments in your inbox labeled ‘Held for Review’.
(It is awaiting your approval there).
Till then, readers can find that discussion by googling for "[SOLVED] How to snap an image to origin" (including the double quotes).
In CAD when you measure a part do you have to commit to that measuremet or can you say....meh instead of 38mm I'll make it 40mm?
Depends on the end result your looking for and any tollerances you want to incoperate for example 5mm holes are going to be dead on 5mm. So if you have something that fits exactly in those holes then you need to add remove a little so, say the pin will fit. Or if your replicating something exactly.
I tried a different approach to create this geometry:
1. Created three concentric circles.
(The inner two circles are to create the wall of the cylindrical body, and the outer circle is to construct the ribs.)
2. Drew 2 lines parallel to the x axis, on either side of it.
3. Drew 2 lines parallel to the y axis, on either side of it.
My idea was to join the intersection points between the circles and the lines to create the four ribs.
(I would have trimmed off the rest of the outer circle.)
But I am unable to make the circle intersect with the lines.
I tried to add a point on the circle and tried to add "coincident" constraint to create an intersection between the circle and the line.
But that also does not work.
Why is this happening? What should I do?
How you hide the top plane at 6:41
Press the space bar key on the keyboard. Or right click, hide.
had to skip all these, the latest freecad doesnt have the image workbench. it says theres a way around it bt i cant see it
If you look at the following video it explains the process that you have to follow now. This is using the import and scaling within there th-cam.com/video/WhxDAgskcHA/w-d-xo.html
Reference image not public nothing to open/download
Just had a look at www.patreon.com/posts/68032339 and it's public let me know if your still having issues
This is probably good teaching but is it really a good program? My gut instinct is this program has so many long winded ways of creating what is really a very simple object. I'm 5 videos in and I question whether I should look for something better. Is there something better? Please be honest.
Where is the beginning of this series? The starting point?
There is a play list that holds all the parts. I thought I put a link to it in the description of each part, I will check the description in this video as I'm not sure if it's there.

im finding this impossible to follow. basically nothing is working for me. i find myself here for days now and I cant get around it. sorry. I need a diferent method I guess
Watching this for free feels illegal
I struggled with this damn sketch it literally fumed me
