I am jealous. I ran UG(sorry will always be UG to me) for 15 years and didn't ever experience it in 3D. I did immediately fall in love with the spaceballs/3d controllers. I added the initial 3d controller support in FreeCAD years

Great comment! I think the size and scope of BRep modeling kernels is lost on 99% CAD users. IMHO: I have reached the point where I think there should be a generation of library development before a CAD application is even considered. This

I evolved from pencil and paper, to text files, to minder. I stick to text and it works good for me. It is simple, fast to use, search works good, basic organization is there. Files are local and xml, so data is easy to extract if needed, b

I have been working on an open source MCAD application called cadseer. https://gitlab.com/blobfish/cadseer

Always great to see more people putting in effort toward opensource cad. Good luck!

Anybody building open source tools for c++ is great, so thanks. Most confusion for me happens around dynamic dispatch. I want a good tool to generate and control dynamic call graphs.

I guess we have a disconnect. I am talking about modeling kernel geometric definitions and data structures. Whether NX has or doesn't have the boolean terms (union, intersect ...etc) doesn't change the fact that parasolid is BRep.

Thank you. I definitely could use help on the other platforms(mac, windows). I spent a huge amount of time deploying on those, which makes it great to hear it is running for you. Sure any PRs for bugs are great. If you want to take on somet

brl-cad is CSG modeler with some BRep support. Opencascade is a BRep modeler that supports boolean operations. The industry gave up on CSG and went BRep decades ago.

In what ways is freecad using opencascade incorrectly?

I am always trying to make it better, but I am years away from removing the 'alpha' description. Cadseer is for the early adopters and the CAD curious. Production minded people should look elsewhere for now. This is open source, w

I have never used openscad, but from what I understand there would be 2 major differences. The first is the geometry engine. Openscad uses a mesh modeler, where cadseer uses boundary representation(opencascade). The second is the user inter

Any feedback is welcome. You can import and export step files. There is no support of assemblies, so I am not sure what you will get.

cadseer is using opencascade, so it is BRep instead of CSG.

cadseer uses opencascade, so BRep. Any feedback is welcome.

I am using opencascade and doing solid modeling vs mesh modeling. So cadseer is closer to something like freecad vs blender. A list of advantages and disadvantages should be done by somebody without bias. I will give you an example: I have

No it doesn't have any assembly at this point. I have used the solvespace engine for the sketcher, so I think I can use it for assembly also ... someday.

If you are just starting with 3d modeling, you have a learning curve ahead of you regardless of the software. I am not sure at this point if I should be giving you advice.

I think most will agree open source cad is lacking. At least in the 3d solid modeling world. Philosophy? Tough question! I guess, "Everything Should Be Made as Simple as Possible, But Not Simpler".

I made a screen cast a few days ago. https://vimeo.com/813202571 If you watch that you can see the sketch mode. Sketcher need a lot of love. No I didn't write a geometric kernel and I am using opencascade. I think my f
