A couple of things I have noticed and maybe I''m doing them wrong.
1) With DrapeElement set to true, DrapedDensificationDistance has no effect (I try setting it to 1 or 5 for example).
If I create a line from 0, 0, to 40, 40 the line seems to go under the earth until 20, 20 and then pops up again to the surface at 40, 40.
2) With DrapeElement set to true, DrapeZOffset set to any value whether it be 15000 or 1000 or 100000 has no effect.
Am I doing something wrong or are these actual bugs?
