Hello,
I am trying to use Civil 3D VBA to get some specific contour lines in a surface built from points.
I can get the surface by the AeccSurface class.
But I don't know how to get its contours.
There is a way to change the display style to let the surface
display contours. But I can get the whole surface only.
There is a class named AeccSurfaceContours.
But it seems that it has nothing to do with AeccSurface.
Hope to explode the surface is not the only way to do it.
