There are three tools:
Properties: Get the properties of the object selected.
Measurement: Get the distance of the two objects selected.
Angle: Get the angle between the two objects selected.
For easier selection, there is a topology filter
There are keybinding shortcuts for the topology filters :
- "v" : vertices
- "e" : edges
- "f" : faces
- "s" : solid
- "n" : none
- In any of the tools pressing "escape" will delete all the selections
- "backspace" or "mouse button right click" will delete the last selection only.
