The Constrain 45 Button: Constrain Angles
When the Constrain 45 button in the Edit Menu is active,
wire and polygon vertices are constrained to form angles of multiples
of 45 degrees. By default, a ``smart'' path generator is employed,
which will construct a valid path to the pointer location from the
previous point during wire or polygon construction. This will often
add two vertices: a 45 degree extension, followed by a Manhattan
extension, in order to connect the points. If the Ctrl key is
held while the new point is defined, the ``smart'' feature is
disabled, and only one new vertex is added. If the Shift key is
held, then the 45 degree constraint is removed entirely.
When active, rotation angles available in the spin command, and
translation angles in the Stretch command, and the vertex
editors for polygons and wires, are constrained to multiples of 45
degrees. However, pressing the Shift key will remove the
constraint in these commands while the key is held. If the Constrain 45 button is not active, holding Shift will impose
the 45 degree angle constraint. Thus, the Shift key inverts the
effective state of the Constrain 45 button in these commands.
