Move along a Line
Command - PrB_LineMove
This tool allows you to move a part in the same direction as another part's edge.
So in the below case the orange line is selected, and this allows us to move the plate along the inclination of the profile.
The advantage of this tool is that it replaces 2 handlings if we wanted to do the same thing with a standard move command : First set the ucs according to the profile, and then do the move command.
