Hi all,
I'm not sure even how to phrase this question without making it sound to long winded,but here goes:
I have a utility survey (gas mains, watermains, telecoms etc.) which is made up of 3D polylines.
The problem I have is that they are relating to a datum of 0, so that the Z value of each vertice
is really only the depth below ground at that particular point.
What I need to do is raise each polyline so that it is draped onto the surface and then lower
each line to the correct depth below the surface (its current Z value)
While I can get a list of all the coordinates of each 3DPolyline,
I don't know how to interact with the Civil 3D surface.
Any directions, advice would be most welcome.
John
