If there is music in this video, it is legally used.
I really appreciate that your videos take an approach that shows how you would construct geometry for the body you're trying to create, rather than demonstrating a particular FreeCAD tool and working from there.
Thank you! It can be helpful to see a part made from zero
I second that!

17:40 - don't remember values, name them! All constraints can be named, and then referred to by paths like Sketch001.Constraints.StrideX. And that applies to all sorts of fields; for example, (Occurrences - 1) * Sketch001.Constraints.StrideX is a perfectly valid formula for the LinearPattern.Length field.
Two little flaws of FreeCAD's UI though; the formula isn't properly recalculated inside the MultiTransform editor (that's why we have mark to recompute and recompute commands, to sort such misses out), and the constraint value editor turns reference mode off for constraints.
Another tiny tip: if you select a point before hitting Shift+H or Shift+V to constrain it, you don't need to also select the origin, it's done by default.
Looks great! Thanks for mentioning the shortcut keys when you're explaining. It's very useful.
I know this is a few years old now, but this video was a life saver. Thank you for teaching me how to use multitransform / cut. Making individual hexagons doesn't work out very well...
Finally someone has come away from Solidworks and is back using a real man's software!
Indeed! I have to use SolidWorks in my job, I guess to keep me in touch with my feminine side
Love to know what dress down day is like?
@@MrCoffeypaul It's pretty scary!
Nice statement! Feel my balls grow already :) (Although i was using Catia 4, 5, NX 11
and a little Wildfire Pro Engineer 2, 3)
This is a great surfacing tutorial! Nice to hear about DesignSpark Mechanical in the comments too.
Mad skills! Thank you for sharing this. Subscribed.
Fantastic video, so many things to learn.
Thanks a lot!
I just wanted to say that you are amazing! Thanks a lot for all that you have shared on this channel. You make CAD fun to learn in a pedagogical way. A lot of love from Sweden!
Many thanks!
Thank you so much for these videos. My goal for the next 12 months is to really learn FreeCAD and your videos are a huge step in that direction.
Your tutorials are super amazing
Learned a lot! Thank you!
That was awesome, thanks!
Crazy skills. Thank you. Subscribed
Nice tutorial! Just a tip, there is a symmetry tool in sketcher! No need to draw things twice ;)
Really good tutorial, I love your channel
Thank you! I'm trying to make the switch from DSM. Very well done sir. Clean. No superfluous jabbering on. Just the kind of presentations we need to learn this program's intricacies.
Thanks! DSM is something I'd like to learn more and eventually add to this channel. Enjoy FreeCAD!
DSM = DesignSpark Mechanical? What made you decide to switch away from it?
It's great! Thank you!
I learn a lot from you. Some steps are very tricky, e.g. sweep works in part wb and not in part design wb. Think about copy and scale basis sketch - it is possible in many ways.
These videos are awesome. Curious: @1:50 the Edge Import Tool isn't working per your instruction. My previous sketch appears as a dotted line and the end points aren't selectable. What does a a dotted line mean?
Btw, would you mind sharing how you customized your UI? I started with with the dark theme but can't locate how to change the font colors. You have legible white fonts, as where mine reflects the dark soul of the unspoken one. Even with my reading glasses on.
What a magnificent tutorial! Thank you.
Do you use any special FreeCAD version?
Because at my computer multitransform feature is so slow, it's painful to use. Whenever I add second axis it requires 30-50 seconds to recalculate every time I change a thing.
I've searched internet and I found that I'm not only one with this issue but I see yours working very fast. I do have quite fast computer (Ryzen 5 3600 + 32 GB RAM) with Ubuntu 18.04LTS + FreeCAD 0.18.4.
Very informative
Your tutorials are fantastic! For some reason freecad complains when I try to apply a horizontal or vertical constraints to 2 points as you are doing in several of your tutorials. It says that it needs a line segment for this constraint or something like that. Do you have an idea why?
I'm using freecad version 0.18 on Windows.
Thanks
Roland
thank you
Shapebinder! to import feature from another body!
great stuff... is there a ready to use hardware workbench in inches for bolts and NPT pipe fittings? because our machine shop has both brass and steel rod material 3/4" 1" 2" etc and in 25mm 50mm etc? seems like freecad has lots of mm units bolts and nuts, however many projects still require inches... thanks a lot...:)
Thanks
I wonder if (at 7:02) it would be possible to select all lines and arcs, then duplicate and scale down, in order to avoid drawing it all manually ?
Another question - do you think it's possible to draw a gear, say with 40 teeth, then change the number of teeth easily (by just specifying one number), so you get a 64 teeth or 36 teeth gear ?
(I know it's possible in something like OpenSCAD where you're writing a program to create the actual model, but it looks to me like FreeCAD might be sophisticated enough to enable you to do this).
For comparison, I can use the rotation-tool in SketchUp with a component and then use the 'divide' feature, but this means you'll have to start from a single tooth each time, plus the teeth won't automatically 'resize'.
Hey 68HC060; I am not aware of offsetting a sketch being a thing in FreeCAD yet (always learning) but that would be a fantastic tool. For the gear teeth, I recommend making a solid and extruding one tooth. Then do a circular pattern to determine the number of teeth. You could even link spreadsheet equations to the dimensions so the diameter of the gear updates with the number of teeth. Good luck!
Spreadsheet equations, that's pretty cool. Thanks. =)
Question: Can a surface be made from two NURBS curves? Also is there a way to import NURBS curves from Excel, or .csv 3d curve vectors?
There must be an easier way to apply a bump / texture map surely ?
I want to thank you, I'm really learning fast with your tutorials. When you scaled the larger body by 0.95 at time stamp 26:09 you said that this gives a consistent thickness. I think that's not the case, for example if you have a long and narrow prism the 0.95 factor will result in a thicker wall on the end walls and thinner on the sides. So this workaround is not parametric as you said but also is not the same as a consistent thickness shell. Right?
Yeah I wasn't very clear. You're right, and that's one reason why I don't like doing it. Bosses off axis wont be aligned, etc. If you look at my grabCAD you can download a version where the thickness command worked, but it didn't work doing the video which was also frustrating.
@@JokoEngineeringhelp It would be nice to know the reason why the procedure crashes, perhaps acute angles, or less than thickness radii?
Hi I'm trying to follow your tutorial but I'm in .18. I don't know if that's the problem but I can't edge import to a single point to connect the b-spline to. What version are you running in this video? Thanks in advance.
Running version 0.18. Points won't import if you're importing from a foreign body. Could that be the issue?
Can you show how to make an aerodynamic model rocket fin? One which has a blade-like edge, and is thicker towards the base for better strength. It would be easy for me to just make it out of straight lines, but I would like one made from curved shapes. What you did in this video looks like what you would have to do for a fin. To be clear, I'm taking about a highly advanced fin, one which has a unique curved silhouette from every axis plane, if that makes sense.
Can you post a link to an image?
@@JokoEngineeringhelp I was trying to find a good image but no luck. I found this one, which illustrates the shape on the XZ plane. "Version 1" is what I mean. cdn.instructables.com/FHO/ZXZV/HE07PPOU/FHOZXZVHE07PPOU.LARGE.jpg
Then, in addition to that shape, not just a bevel along the edge, but a _sharp_ edge.
THEN, on the XY plane, the base looks like an isosceles triangle, the sides of which curve inward, with a sharper angle towards the base (so it's wider where it attaches to the rocket) for light-weight, aerodynamic structural integrity.
I guess you probably have already covered a lot of this just in other videos so could you maybe point me in the direction of something that could teach me how to do this? Thanks :)
@@JokoEngineeringhelp OK, if you can make a simple curved wing, such as in this photo, i.pinimg.com/736x/fd/7f/fd/fd7ffd4d0b59a5e98446f9ecec095ee3.jpg that would teach me what I need to know. Is it possible in FreeCad?
@@JokoEngineeringhelp I assume you know what wings and airfoils are shaped like.
@@tristunalekzander5608 I think I get what you're referring to. I'll make a video on this
