What does XLarge mean in XyzPilot?

XLarge is a direction selector that picks the solution with the largest X coordinate when two solutions exist.

Full Answer

XLarge selects the solution whose key point has the largest X coordinate. It is used when a geometry operation produces two valid solutions and you want the right-side or largest-X result.

Selector	Picks
`XLarge`	Solution with largest X coordinate
`XSmall`	Solution with smallest X coordinate
`YLarge`	Solution with largest Y coordinate
`YSmall`	Solution with smallest Y coordinate

Rule: Use the selector on the axis where the two solutions differ. For a vertical line intersecting a circle, both intersections have the same X — use YLarge/YSmall instead.

XyzPilot Example

L0 = Horizontal line at Y=50
C0 = Centre (75,50), radius 25

Point/XLarge, Intof, L0, C0
→ P0 = (100, 50)  [right intersection — largest X]

Point/XSmall, Intof, L0, C0
→ P1 = (50, 50)   [left intersection — smallest X]
