What's the best way to bring a 3D surface into Revit and have it maintain it's correct elevation? I've tried importing (via data shortcut) the surface into a blank drawing, promoting it, exploding it with the triangles on. Okay so far. Now, since the scales are different - I.E. civil scale is 1/12 that of an architectural - when I scale the exploded surface by a factor of 12, my finished grade elevations are now 12x's higher than they should be. Does anyone have any suggestions?
