BRL-CAD uses STEPcode, and FreeCAD is investigating using it for higher-level data along with the OCC translator for geometric shapes. (FYI, I have been in contact with the OCC team, and they would be interested in using STEPcode if it provided them improvements with large files. Paviot from OCE sa...

Ok, thats a very special niche you have there. Besides high energy particle physics, radar perception and nuclear explosions I know no use-case for engineering? I work in the automotive field and our main simulation instrument nowadays are FEA. Astute observation. There actually are many other use-...

Does that mean that you also support importing files in 3DM format? Yes, in fact our in-memory representation is actually openNURBS format too. A 3DM import is literally "pack this 3DM data into our file". We use their routines to read/write the data and their API for interpreting/creatin...

One of our long-term objectives is to create a stand-alone geometry kernel that is viable replacement for acis, granite, parasolid, cnext, etc. Raw capability-wise, we're actually almost there. Ok, I am listening! Any pointers for exploring the brep geometric capabilities of the brl-cad api? Apprec...

Is there any chance you could elaborate? I am interested for myself, but it would also be good to know if BRL can do something that FreeCAD can't, so we could direct anyone asking for that functionality to BRL. :) Jim, there are two areas in particular where we're fairly unparalleled. Geometry repr...

Sean, what you said about BRL-CAD is very intriguing. Did I understand correctly, 10 man-years are put into developing BRL-CAD every year? :shock: I assume some companies (or government agencies?) are financing BRL-CAD's development? Yes. Development was initiated and has continued uninterrupted si...

Apologies in advance on the length! I'm in awe at the amount of incorrect misinformation attributed to BRL-CAD, but this is very educational as it is an outsider CAx group perspective. Thanks to everyone that responded thus far. As jreinhardt noted, this is interesting albeit somewhat off-topic to t...

I know most everyone here is probably at least peripherally familiar with BRL-CAD, so I'll skip an elaborate introduction. I'm the project lead and I'm hoping to collaborate more than we've done in the past. Towards that end I'm wondering if there's any interest amongst FreeCAD core developers to pa...
