Is there a way to lock the angles of lines?
I would like to be able to set a line’s angle and then resize it by grabbing one end and dragging it around, without concern of changing the line’s angle.
The "Rotation" box here appears to not be relevant.
It's possible to lock the rotation of a two-dimensional object, but not of one-dimensional object which is the line.
You would be better off by changing the line's length via the Size & Position window, rather than by dragging the end-point.
