I am trying to export a shapefile from ArcGIS 10 into Autodesk Ecotect Analysis 2011 for solar analysis. I have a shapefile with polygons, and the heights of buildings is stored in the attribute table. I tried saving it as a KML file but Ecotect does not import KML files. Instead, Ecotect would accept any DXF or 3D files (such as 3D Metafile and 3D Studio).
Is there a way of saving 3D files from GIS other than KML?
I tried importing KML into Sketchup and Autocad without success.
Any other idea for exporting shapefiles into a software that can extrude them and save as 3D would help too!
