How to select polygons created by drape?

[mstoddard]

I draped a polygon roads layer onto my terrain (Tools > Sandbox > Drape). The terrain is a TIN exported from ArcGIS. Is there a way to select all the polygons created by the drape? I want to select them, group them, and color them dark grey.

I know I can manually select the polygons and add them to a group, but this would take some time.

Thanks for your assistance.

If you smooth the TIN completely before draping, then the draped lines are left unsmoothed. Then you can just select the road face, and it will select all faces within the road. Double clicking should select the road and its edges if you would like. Then group those.

If the shape you drawp is closed, then this method generalyl works very well for me. Did that make any sense? It might need some images to help explain easier.

Thanks Chris! Your tip worked. Just what I needed.

The edges Drape creates will end up on the current layer. So if you create a temp layer for the drape and set it as active, then you can afterwards select one of the draped edges and Right-Click -> Select -> All On Same Layer.

That way you can be 100% sure you get all draped edges.
