How do I create a point at the midpoint of an arc in XyzPilot?

Use Point/Midpoint,A with the arc reference. Creates a point at the midpoint of the arc sweep angle.

Full Answer

Use Point/Midpoint,A. Creates a point on the arc circumference at the midpoint of the sweep angle. This is the point equidistant along the arc from both endpoints.

XyzPilot Example

A0 = Arc: centre(0,0), r=50, start=0, end=90 CCW
Midpoint angle = (0 + 90) / 2 = 45 degrees

Point/Midpoint, A0, 0
→ P0 = (35.355, 35.355)  [at 45 degrees on the arc]

A1 = Arc: centre(0,0), r=30, start=30, end=150 CCW
Midpoint angle = (30 + 150) / 2 = 90 degrees

Point/Midpoint, A1, 0
→ P1 = (0, 30)  [at 90 degrees — top of arc]
