Topic: FreeCAD OEM Version

[GeorgeStevens]

Hello everybody
I am a trained building technology planner with a higher degree. Since I've been working in this industry for a long time, I've made various experiences with various CAD programs. In Switzerland, where I come from, the guidelines for building technology such as the Drinking Water Act, energy use, drainage, etc. are particularly tightened. With all the experience I would like to extend the FreeCAD with my own "applications". I find the CAD super easy to use, but would like to expand it specifically for building technology.

Is there such a thing as an OEM version that I can tinker with a bit?

Thank you in advance

Is it this FreeCAD?

if so it's open source and it has an extension interface/s
