FreeCAD: Understanding The Part Design Multi Solid Support | Single Sketch Multiple Profiles
ฝัง
- เผยแพร่เมื่อ 31 พ.ค. 2024
- Part Design workflows in FreeCAD don't support multiple solids in one body but the part workbench does. We explain in simple terms what a multi solid object is and how it can be created, learn about intersecting profiles and venture into using multi solids as base feature in the part design. All of this to help beginners understand and to give examples of this challenge in FreeCAD.

I swear, this guys channel is the only reason FreeCad even still exists. I wouldn't have made it past the Start page without this channel.
Glad these tutorials are helping out and I am able to get people up and running. Thank you so much :)
These kind of fundamental concept videos are important to people understanding how FreeCAD works and avoiding frustration. Well done.
Everytime I watch I walk away smarter. Thanks
Just recently started learning FreeCAD through you videos and kept having this issue when trying to make things outside of your videos. Very helpful, thanks!
Thank you Darren! for another detailed explanation of why certain things in FreeCAD break. Love your videos brother! Keep the excellent content flowing!
Thank you so much :) Do glad I can help out.
multi solid problem can sometimes be very limiting. In these cases I use FreeCad Link version which supports multi solid in Part Design.
That's interesting. I am a beginner and have been using realthunder's fork of FreeCAD because it overcomes the topological naming problem. This video shows me that realthunder's version also has multisolid support!
Yes real thunder allows for that. I know freeCAD 1.0 is taking the topo naming fixes from real thunder. I don't know about multi body solids though. Be interesting to find out.
Should someone make a fork with a little button next to each function that links to the appropriate mangojelly vid? Thanks for your efforts mate
Glad to help out :). Now that would be pretty cool :)
Wow, press control-H when you click an icon and get a tutorial video...that would be somthing... gotta love open source stuff... like Arduino.
This is huge for me. This helps clarify and give me the ability to make better designs. Thank you. Great job.
Glad it was helpful!, I am trying to cover more basics in bite sized videos. Thabk you for the kind words.
Great video gave you a like. Only day 3 on FreeCad. One issue I can't seem to fix:
Part design.
Created a body and sketch.
Created a rectangle in sketch, constrained it totally.
Created a pad for it.
Selected the top surface of the pad.
Created another sketch on that surface.
Created a circle on that 2nd sketch, (I can see the rectangle from the 1st sketch in this sketch).
I brought in a reference from the rectangle from the other sketch and
Constrained the circle to that reference.
Did a whole bunch of things including many sketches, pads, and pockets.
I get no warnings or errors... all looks good.
I go back to look things over.
But in my learning I hit keys that I may not suppose to hit (not knowing I did so).
I go back to that 2nd sketch with the circle I constrained to one point from the 1st sketch rectangle - BUT THIS SKETCH IS NO LONGER SHOWING THE RECTANGLE... my circle and constraints are there but the rectangle is missing from the view (it must be there but not shown).
I played with pressing space, but that does not change anything inside a sketch.
I did find a pull down that turns everything back to visible - but now the 3 planes are visible with the rectangle - but too much now to look at.
All I want to see is the rectangle from the other sketch with the circle and constraints I made to it just like when I started that sketch.
What did I do wrong?
How do I get it back.
This tool has TONS of features but its hard to find things because there are like 20 workbenches and each one does different things, sometimes things subtly.
Thanks.
Thank you, thank you, thank you! I have been fighting with this for weeks. ❤
Glad it helped :)
Can you make a tutorial on the Freecad FEM workbench ? all the current tutorials out there are not very informative or is severely lacking in showing how to use it correctly.
oh neat, now I know how to get extruded text where each letter is separated. I always default to the Part Design wb, I need to branch out more I guess!
Glad it was of help 😊👍
Another great explanation.
Great videos on the maddening idiosyncracies of FC. Superb resource. Thank you.
Thank you. Great explination.
Thanks for sharing 👍
When it says "not supported at this time", that makes it look like it may be supported in a future version?
Hopefully, real thunder supports it and they are taking the topo naming issue fixes from real thunder into freeCAD 1.0. I wonder if they will take the multi solid support as well.
@@MangoJellySolutions Would be great if they could take multi solid support from real thunder too.
Thanks for your excellent videos. I have experience in using Ansys to do FEA analysis where it is rather easy to split faces in Space claim for solid bodies that is sometimes required to identify contact areas or load distribution on solid bodies for FEA analysis. I am new to FreeCad and I'm battling to split faces on solid bodies in FreeCad in order to do FEA analysis in Prepromax. Is there a video of you that you can recommend for the splitting of faces of solid bodies for analysis in Prepromax or is there a function available in FreeCad for this?
you can use boolean fragments. check the tutorial series of FEAnalyst, there he shows in one or two videos how to do it
You can make a sketch on that face and make a pocket to the other direction so that it will not affect the thickness.
For example if you want to make two separate rectangles from one rectangular face you can make sketch on the face you want to split and draw one rectangle and make a pocket to the other direction and make sure the refinement property is set to false

Thanks. This helps alot and works 100%. Can you maybe advise on how to split a face on a roundbar or any face that is not flat? Your help is highly appreciated
You can draw a rectangle that just touch the round surface and then revolve it around the round face and chane the angle to what you need.
Or you can use the a tool called sketch on a surface I am not sure what was the name of it but it's available on the curves workbench which can be installed from the addon manager
@@muezabdalla2852
Thankyou once again. This makes sense to revolve. I will test this. Shalom
Hi. Do you have an update about PLM functionnalities in freecad ? Merci :)
What's PLM in this context?
@@SpaceMarshalGyorni PLM stands for product lifecycle management. Its a very important aspect of product devloppement. It aloud the users to track what is in work , frozen, released or obsolete.
I think the Onsdel layer may be tackling this area as it adds that business layer on top along with their Lens offering.
@@MangoJellySolutions oh interesting. I am a bit confused when it comes to onsdel. Its running on freecad but its different? Would you recommend using it? I will watch your videos about this. Do you have a recommendation to design in work frozen release and obsolete with freecad? Merci
For a free tool it is awesome but a bit expert friendly. Like one would think you can draw a rectangle, constrain it's height and width, then select it. Then try to copy it (control c) and paste it (control v) but... nope! Day 3 and I still can't figure out how to copy things on a sketch/part/part design or how to cut from one sketch to another and such. It has about 20 very powerful workbenches, but intuitive features like control-c and control-v (cut and paste) are not there. I have done 3 designs in 3 days but I have to redraw things a LOT because when you get 3 or more sketches in the same body, all with constraints to each other, and you simply want to delete or move something and... it's easy to "break" the design... and what a mess it is to fix... but this tool does the job and doesn't seem to crash. It just takes becoming and expert on it to do designs efficiently without having to redraw and fix things many times during a design.
Is this topology renaming thing still a thing in freeCAD?
Yes, it should be fixed in freecad 1.0
It's a thing in *any* CAD package. It's not solvable, just hide-able and workaround-able. If you understand what the topological naming problem is, you can easily break models in Fusion360 or whatever commercial package you use. Likewise, if you understand the TPN you can easily create stable models in FreeCAD.
@@SpaceMarshalGyorni I admire your background knowledge but a simple "yes, it's not crashing itself anymore if you want to do basic parametric stuff!" Would have been enough :)
