Draping Aerial Images on Existing Ground Triangles

I was previously able to drap an aerial image on existing ground triangles in xm using Descartes and the dcdrape.pal. It appears that this is now built in to V8i without the use of Descartes. I am using V8i SS2, and using what is shown in MicroStation help I am attempting to do the same without any real success. I am using the dcdrape.pal and have the draping option toggled on in raster manager, but cant quite get it to work. Seems like it should be relatively simple, so I am thinking that I am just missing something simple.Could someone please point me in the right direction to get this done? Possibly a list of steps with screen captures etc. I can provide my data if needed.

Thanks so much!!!

  • Hi Dan,

    probably the most simple steps are:

    • Create your DEM, check they are closed traingles or mesh, not just lines.
    • Place a raster, so it is correctly positioned over the DEM in the top view.
    • Set draping switch in Raster Manager on.
    • Assign dcdrape material from dcdrape.pal palette to the DEM elements. I use assignement by level/color as DEM is usually in one level, not attachement to a particular element.
    • Render a view.

    It is all you need.

    BTW What is the result if you render a view or use Smooth display style?
