Drape Surface


BG

Recommended Posts

I Can't get the drape surface command to work on a DTM.

The dialogue box doesn't appear, just says drape surface failed.

The file is attached - any help appreciated.

On another DTM, the drape surface command runs, but the surface created has no height?

Thanks

BG - The Drape command works for me if I set the DTM 3d display to 3D Triangle. Drape fails if the DTM is set to 3d Contours (that's condition of the file when downloaded)

Also, the DTM is many mm above the ground plane, causing the drape to be very long. The drape dialog z value can be set quite high - I used 321500.
