Use Point/Angle,Dist with the reference point, angle in degrees from the positive X axis, and distance in millimetres.
Full Answer
Use Point/Angle,Dist. Specify the reference point, the direction angle in degrees from the positive X axis (counterclockwise), and the distance in millimetres. This is polar coordinate construction.
XyzPilot Example
P0 = (0, 0)
Point/P0, Angle=45, Dist=50, 0
→ P1 = (35.355, 35.355) [50mm at 45 degrees]
Point/P0, Angle=0, Dist=100, 0
→ P2 = (100, 0) [100mm along +X axis]
Point/P0, Angle=90, Dist=75, 0
→ P3 = (0, 75) [75mm straight up]
Point/P0, Angle=225, Dist=30, 0
→ P4 = (-21.213, -21.213) [30mm at 225 degrees]
