Hi can I throw a similar question in here?
I have always designed my 3Ds on a flat surface for simplicity and as such have never needed to send plants to surface of a 3D site model.
I now have to do the dreaded contour 3D design! I created a site model and added it to my design. But all the plants are still sitting at Z=0 elevation and the site model starts at 6m. How do I tell the plants to conform to the site model elevation?
To clarify, I created a site model on a new layer and dropped it into my finished 2D design. Any new plants I create are sitting at correct elevation but the existing planting is all at Z=0.
