#23 Cleaning / Saving

[Bernie]

Hi all, I am looking for help with two issues: First, is there a way to delete points in a point cloud by their distance (low density), or is this just possible for meshes (select...edges longer than...)?
And second, is there a way to save the point cloud after the application of the "align to principal axis" filter? I can see the correct rotation on screen, but I can not save the point cloud with these new coordinates. Is that possible?
Thanks a lot for the help

Bernie
