Cull/Cut by Low-Density tool.

[JMR]

Hi all:
Thanks Alexey, that was a very good feature addition
I have a more ambitious suggestion. I'd call it Advanced Selection Tool dilalog
On top three Radio buttons for Selection mode: "select" "deselect" "toggle"
Main select box for: Islands, Triangles
Options for "Islands" aka "shells":

• With poly count >= than X
• with poly count <= than Y
• with poly count between X and Y

Options for Triangles: by area, by aspect(Lmax/Lmin), by diedral angle, by longest edge lenght

• value >=X
• value <=Y
• value between X and Y

This would help to clean meshes by deleting "spikes", noisy areas, and the so-called low density areas

Apply button should run selection over existing selection set if existed according to selection mode: "Select" will add new elements to current selection set, "deselect" will do the opposite and "toggle" would alternate current status for selected and non selected elements. A similar selection mode behaviour should also be available for all already existing selection tools in addition to the hopefully comming very requested irregular fence/laso selection.
Very best Regards!
