[Manifold-l] 3D object

[CDollfus]

Hello,
i'm using Manifold since version 5. I really like it. I use it in my 
windturbin project (locating and calculating visibility area)
i suppose developpers will soon add function to overlay 3D object. 
Before this date, i wish an advice to make possible this little work:
- i have a windturbin layer containing 3 points with height (100m)
- another layer contain the DTM,
i would like to make a 3D view from a point view representing the 
windturbin correctly. Of course i have Manifold surface and a flat image 
of the winturbin.
thank you for any help,
