Draping a 2d polyline onto a 3d surface

Hi.  I am wanting to digitize a geology map using AC Map 3d.  When I draw 2d polylines of geology units, I would like to be able to drap these onto a DTM suface so I can have them in 3d.  How do I do this?  Thank you.

I believe you have to have your polylines set up as an FDO along with your DEM.  PLace the polyline layer over the DEM layer and click the 3D button on the bottom left of your screen.  You should see your DEM and the polylines drapped over it.

Unfortunately this is only a "visual" effect, because no physical 3Dpoly is created...
