Screenshot exemples of a complete building i’ve modelled in 3DS Max, For this one there were no autocad files and I had to work with multiple cross-sections drawings for reference.
Walls where first built using an editable spline layered directly on the blueprint images, the roofs where especially tricky since they were not aligned on a specific axis but had to be extrapoled from different views of the cross-sections.
I used extensively groups and instances for all of the windows and associated shutters, interior walls were also modeled and I put each floor in a different layer.
With this modelling work done, I passed it to a collegue who finished the render.
