Good morning Claus,

your suggestion fits to something I have in mind for a future release.

For CAM functionality I think about a "verify" menu with several tools to improve a drawing:

• show endpoints of entities
• show vector of entities
• show intersections
• show none tangent connections
• show gaps in continuity
• show small entities

All these tools may highlight positions in a drawing for a manual improvement.

I think your request fits in this menu as "show overlapping entities" or could be included in the intersections tool.
Deleting identical entities should be easy, but what if one or more entities have different attributes? If you have changed the colour or line style of an entity, how should the tool know, which one has to stay in the drawing?
Another case are overlapping lines which have no common endpoints. Two short lines which look like one longer line, but the second one starts somewhere inside the first one, not at the endpoint. Or a short line which is totally overlapped by a longer one.
Sometimes this is intended by design and should be kept, but for CAM features this could be horror.

So I see the problem in deleting entities automatically. What I can imaging is a semiautomatic way by listing the shady entities and select the ones to delete.

Regards
Armin
