Here are references to how draughting is currently implemented in STEP. However, Normand is right to point out that STEP translator implementations cover only select portions of a schema. STEP AP201 and AP202 draughting capabilities were incorporated into AP203 edition 2, which is superceded by AP242. I don't suppose FreeCAD can edit and display that component? Moreover, the STEP files produced are readable in FreeCAD, albeit without the 2D drawing file component. I am currently trialling a budget 3D CAD modeller called ZWCAD, (the value of our local currency here in South Africa prohibits the purchase of Autodesk and similar licenses) and it seems to be capable of generating the required file. This worked after a fashion, but I was asked to produce STEP files which incorporated the 2D drawings in the same file as the model. I had used Freestyle to produce (imperfect) svg vector files which I wrote a simple python script to convert to DXF, which I then imported to ProgeCAD (an IntelliCAD clone) where I added Drawing border blocks, dimensions, plans, elevations, sections, details, etc.

I had a requirement to provide 2D drawings of a plant I had generated in Blender.

Forgive me for cross posting, but I'd started a thread on converting DXF files to STEP and, although this post is a continuation of that topic, the subject matter has altered enough (in my view) to start a new thread.
