Dear Ken, just use File>save as>*.ers while only your vector file is open in the Algorithm window. It is best solution if you want drape filled poligons on topo. You can drape vector lines with the same method but then you can not show vector on 3D image (image + DEM). Unfortunately, I could not find a easy solution that prevents topography from "cuts thru" the vector polygons in 3D views.
I hope this helps Best regards Yucel --------------- Yucel Erbay NIK Insaat Ticaret Ltd. Co. Softwares & Satellite Imagery Distribution Construction & Restoration http://www.nik.com.tr Ortaklar Cad.

When I try, the topography "cuts thru" the vector polygons in 3D views. I though maybe I have to save the polygons as raster regions to get them to drape correctly, but when I use the "save as" option in the "tools" dialog box I get an error saying "dataset header file for region output doesn't exist". What does this mean? How do I convert a set of vector polygons intot raster regions?
