FAQ

How do I create a line perpendicular to one line and tangent to a circle in XyzPilot?

Use Line/Perpto,L,Tanto,C with the reference line, circle, and direction selector.

Full Answer

Use Line/Perpto,L,Tanto,C. The line is simultaneously perpendicular to the reference line and tangent to the circle. Two solutions exist — the direction selector specifies which one.

XyzPilot Example

L0 = Horizontal line at Y=0
C0 = Centre (50,40), radius 20
Perpendicular to L0 = vertical lines
Tangent to C0: X=30 or X=70

Line/Perpto, L0, XSmall, C0
→ L1: vertical line X=30 (left tangent)

Line/Perpto, L0, XLarge, C0
→ L2: vertical line X=70 (right tangent)
