Flattening a Survey

[jritterw]

Is there a quick way to flatten a survey that has multiple objects with Z values?
I tried the flatten command, but it says that many objects can't be exploded.
There are also proxy entities, topography lines for later rendering I think, are
these causing problems, help I dont know what to do!

Where did you get the file? Are you using the survey portion of C3D? What program and version are you using?
