Commenting post 37: I am working currently on a project where we generate an IFC file to represent the infrastructure of railways - not only the rails, of course - Although i know that IFC cannot precisely describe railway objects as it could, we would like to use the IFC generic structuring capacities above STEP-21 geometry to perform some tests. I have downloaded FreeCAD on my PC (Windows 7 64 bits), but it seems that IfcOpenShell is a mandatory part to import an IFC file into FreeCAD. I do not have the capability and the knowledge to "compute" things, as you write, to update my environment. Is there a solution to get a "beta" release of FreeCAD + IfcOpenShell that could be installed (easily) on a Windows 7 PC ? Thanks.
