Retrieve information about a subtool's geometry and also a way to check if two subtools overlap?

[spirosm]

Hello,

1. Is it possible to retrieve information about a subtool’s geometry (e.g. points faces, and their coordinates - position) and manipulate them programmatically (e.g. move a point +1 on the z axis)
2. Can i check if two subtools overlap in space?

many thanks!
