Improvement of Horizontal / Vertical constraints, edit modes on part and assembly are not consistent

[ReneRepina]

Hello.

Improvement of Horizontal / Vertical constraints is needed, because we know that this logic is connected to local coordinate system orientation and problem arises when this is used in "edit" (from assembly) mode and also display of lines is not consistent with selected fucntion (for example Horizontal constraint) compared to visual line (it shows Vertical lines).
See images below.

Edit (in assembly) mode, horizontal function, horizontal visual, but it throws an error, because program thinks we want to do a vertical constraint:

Part edit, horizontal function, vertical visual, works correct:
