dir seems magic to me. I don’t understand how it works, not even how it can be used for drawing not having an origin.
All MP drawings have an origin (0,0). (dir angle) returns a pair on a unit circle surrounding the origin, i.e. (cosd angle,sind angle) where cosd is the cosine function operating on an angle in degrees. Alan
