How do I find the intersection of two circles in XyzPilot?

Use Point/Intof,C,C with a direction selector. Two circles intersect at two points — the selector specifies which one to create.

Full Answer

Use the Point/Intof,C,C operator. Two circles can intersect at two points — the direction selector specifies which one. The result is computed using the radical axis method — exact analytic, no iteration.

XyzPilot Example

C0 = Centre (50,50), radius 40
C1 = Centre (90,50), radius 40

Point/YSmall, Intof, C0, C1
→ P0 = (70, 15.359)  [lower intersection]

Point/YLarge, Intof, C0, C1
→ P1 = (70, 84.641)  [upper intersection]
