Greetings node gurus :thumbsup:

I got a bit of a dilemma of whether or not I should do this the long way - a painstaking move on about 400+ buildings one by one to a correct height, or if I should even attempt to do this some other way.

Basically I have all these buildings that were constructed externally, to their correct respective footprints but for some reason they are all over the place in terms of their respective heights.

I managed to obtain some aerial survey data (ladar scan of non ground as well as ground points ) which I brought into LW & triangulated, & from that one can pluck out quite easily a point/poly on the roof's surface of the buildings in question & then raise their respective externally constructed counterpart to the correct height. Ok for 1-50 of those, but I'm a slacker & want to automate as much of this as possible.

I can kind of get close to achieving this by using KO-Pointfit & the zoom-polygon option but that also involves a bit more manual labour that I'm willing to sacrifice at this stage so I'm here seeing if anyone has done something similar or if this is even remotely possible with DPont's part/poly move node.

One thing I can think of is that one can rig a surface node to shoot a ray and evaluate the distance between two surfaces .... refer to 1st pic below, and I'm wondering if that discrete distance could somehow be translated and plugged into a part/poly move node in order to accomplish something like the animated gif below?

Any help / ideas would be greatly appreciated. In the meantime I'll continue to tinker away. Cheers a bunch :thumbsup:
