I have been wondering as I think moving the bounding box is a little clunky... could there be a way to make this a little easier... for example you could click on the model or point and make that the center of the bounding box. As well a numeric value for the bounding box could help a lot with such a click function where you assign how far on each axis it will go from the click you just did.
The box could as well be used to change rotation and orientation of the bounding box, say you want to flip the bounding box 180° or make it more accurate for height field reconstruction.
I hope I make myself clear on this. And I do think this would be a very helpful function.
Little extra, the numeric window could also have a function where you tell it to move x far from its current position, for example if you want to reconstruct a planar model in passes, you can simply move the box numerically instead of manually.
