We really need an "uncrop-box" to restore only pieces of a point cloud that have been removed.
We'd also love to have a way to separate each box-crop into it's own object so they can be switched on and off selectively.
In addition, some way to use a lasso tool, or a solid body, to selectively crop out odd geometry.
Lastly, some way of auto-generating a solid body that follows the approximate surface of the point clouds would be extremely helpful. Right now I just use cloud points with 3 point planes to make surfaces for measurement and constriants.
