If the main building operations take place on the sides/facade/roof of the structure, can we define those attributes on specific tesselations in the editor once an obj is imported? Can we write any of the data files with attributes from other 3D programs, is there a complete list , OSM,GDB,IMG...
You have this posted in the rather vague category of 'Developers', you might be advised to move it to a specific location to solicit targeted responses. GeoNet Community Structure like is this for the web? arcmap? city engine?
