Thanks. Yes both Topologic and FreeCAD are based on OCCT. Actually, before we even built Topologic, we experimented and built functional prototypes in FreeCAD. It is no surprise that many of Topologic

And the thing which is also fascinating is that both FreeCAD/Part Module and Topologic is built on OpenCascade to my understanding !

@paullee that one I had already find out in FreeCAD. The question here is that we shouldn't do that if we want to work with topologic, right?

However this kind of Reference Sketches, in FreeCAD, can't be used for actual geometry. Somehow it makes sense to me to extrude them outwards as, interior partitions are way thinner and dividing inte

So I might as well show you the original hand sketch (which is not made in FreeCAD of course):

@paullee The workflow I demonstrated does start with FreeCAD objects and returns FreeCAD objects. Anyway this is how it can be done in Topologic, but if someone can hack OCCT that would be impressive

I do not know much about OCC, it is the core of Part WB in FreeCAD to my understanding. I see there are methods (exposed in python too) like childShapes(), isSame(), isEqual() that may help to trace

If you are on Linux, try to follow the instructions on github.com/wassimj/topologicPy and if you have FreeCAD 0.19 daily, it should work. The tricky part is always installing cppyy and all its depende

Hope can use that right in my FreeCAD :D

@paullee This was quite easy for Topologic in FreeCAD. Mainly, first make sure the 8 surfaces are selected and then paste the following python code:

Seems FreeCAD file *.FCStd is not accepted, I just rename the extension to *.zip for uploading - pls rename back to *.FCStd

I am not sure. Topologic can read BREP files. If you send me a sample file, I have FreeCAD and can test it.

I wonder if Topologic will be able to read FreeCAD sketches. They are not actual geometry, they are only geometric rulers/constraints... I might be wrong.

1. Use pure python scripts from the console to read and write BREP objects (100% compatible with FreeCAD)

I do not know Revit, Rhino, GH etc. except AutoCAD probably upto 2008, and recently FreeCAD (on Fedora linux) :D
