How to get the elevation of a multipatch draped on a DEM?

Question

How to get the elevation of a multipatch draped on a DEM?
Is it a average of elevations of the extent?
Sometimes it seems to be an integer sometimes it seems not.

Please help me.

I have some pylons draped on a dem.
I want to connect powerlines among them, so I need elevations of all the pylons.
If there is no dem, elevations are all zero.

Use the interpolate shape tool to convert the polygons to 3D. The tool takes the surface and the features as input. Assuming you run version 10. The tool is called covert features to 3D in legacy versions.
