Just an ease-of-use suggestion. If the user changes the guide line location within a beam, the beam doesn't move (good!). On the other hand, the user cannot change the location of the guide line location within a wall without moving the wall.
It would be nice to be able to do both for both types of objects:
- Flip orientation (guideline location stays the same, object is moved)
- Change guideline orientation (doesn't affect position of object, guideline location stays the same)
It might be worth considering implementing this ease-of-use feature for slabs, stairs, roofs, and other objects which use guide lines/planes.
