Hi,
the easiest solution is instead of projecting the shapes to the terrain, use the translate option in the same tool.
otherwise, you can also use
Shape -->
alignScopeToAxes(y)
s('1,0,'1)
to flatten the footprint before extruding.
and / or make sure you use extrude(world.y, height) instead of extrude(height) in such cases.
Cheers!
