I am working on a ‘real-life scene’ of the fields around Zonnebeke and Passendale (world war I), with this I mean that all the data was gathered on the terrain itself and processed with ArcGIS (Arcmap, arcscene). Here we made different layers of buildings, trenches, roads, … and we want to paste it in our blendermodel.
I allready made a 3D model in blender from the surface using a heightmap in black and white (very easy: Import - Images as planes - edit mode - subdivide - modifier - displace!)
But now I want to align my buildings ( I can import them as .dwg, .dae, …) with this surface and this does not work.
I allready tried to extrude all the buildings and do a boolean but this doesn’t give the right result.
At the end of the process, the model will be milled in one material and used in a museum with a scale 1/1350.
Can somebody please help me? (the buildings is the first big jump, then I have to cut out trenches!)
