Not sure - better import it into your real world location and then shift it around therein. > but how do > you assign known location co-ordinates to the base of a wind turbine > (without a copy of AutoCAD).

Then get it into the right position with v.transform (scale x, y, and z). > I might also need to set the height of the turbine but again not sure which > is the best action. The z scale of v.transform will do that. I got the water tower in http://grasswiki.osgeo.org/wiki/Help_with_3D#Vector_3D_polygons like that into the right position.
