straight line angles

Murrayb

while using poly line or a straight line, holding shift provides the ability for the line to stay straight in 45 degree increments. In piping construction we do the majority of our drawing in isometric views. the option to switch the 45 degree increments to 30 degree increments would be very useful for a roll as a mechanical designer and anyone else dealing with isometrics or 3D views

It would be nice to set the increments in the preferences. Maybe a standard increment and then holding down the "alt" key would switch to a secondary increment for those who have multiple preferred angles.
