My line segment tool

[need answer]

My line segment tool no longer (using shift) draws 45-degree lines but makes them 315-degrees. Why?

Also will not draw 90-degree vertically but will draw horizontally. Why?

Can you check if the artboard is rotated?

Or the angle in Preferences > General is set to something else than 0 ?

Artboard is not rotated.

Also Preferences > General --- constrain angle is at zero.

Also, if I double click on line segment and change if from 315 degrees, it goes back to 315 degrees ---- I JUST FIGUED IT OUT. The perspective grid is on...remembering I had this problem quite a while ago. I turned off perspective grid and now do not have the problem. Pass this on if anyone else ever has this problem. Thanks for input.
