I am new to autocad map3D. The work I have to carry out is to create 3D models from a shapefile which has some co-ordinate system. i have connected the shape file but unable to work on it. When i import it i am able extrude it but one by one. Is there any option where the extrude command works for all the polygons that are there in the shape file taking the height of extrusion as the height value given as the attribute in the shapefile. Also let me know how to model the roof. Typically a inclined or a tilled roof.
Thank u very much in this regard.
