my part of the project was to design the layout of the mast and to do the static calculation.
Thats my job since 25 years. Sometimes I draw in freecad for checking complex geometries.
And I can submit monitor snapshots to the CAD-technicians for better explaining them
what I want do build. Then they produce the detailed technical drawings. In Autocad.
The Telekom (like the Deutsche Bahn, see link below) wants all drawing-files in the "original"
Autodesk dwg/rvt-format. The sub-contractors are fully responsible for ensuring 100% data-compatibility
between the cad-systems. They want to avoid stress with the Telekom, so everybody works with
products from autodesk.
