It is now possible to do a cross-drape also. The GT_DRAPEPOLY command has been significantly enhanced. This allows polylines to acquire elevations from underlying DEM data and generate a 3d polyline effortlessly. The GT_DRAPEPOLY command is used to perform interpolation along a polyline and extract elevations from intersecting 3d polylines and 3dfaces along the way. (Enhancement) GT_DRAPEPOLY: Menu: GeoTools -> Build -> Drape a 3D polyline across a set of intersecting linear objects This is handy when you would rather point and click and show the distance rather than actually type it out in the box. In yet another minor but useful enhancement, a Show option has been added in the GT_SPL2PL command to enable users to show the interpolation distance visually on the screen by picking two points.
