What is the difference between CW and CCW in XyzPilot?

CW means clockwise arc direction. CCW means counter-clockwise. The same start and end angles with different directions produce complementary arcs.

Full Answer

When creating arcs, XyzPilot requires you to specify the sweep direction:

SelectorMeaningExample
CCWCounter-clockwise — positive angular direction0° to 90° CCW = quarter circle upper-right
CWClockwise — negative angular direction0° to 90° CW = three-quarter circle going downward
The same start and end angles with CW vs CCW produce complementary arcs that together form a full circle.

XyzPilot Example

Centre (0,0), radius 50, start=0°, end=90° Arc/CCW → quarter circle (90° sweep) Start: (50,0) End: (0,50) sweeps upward-left Arc/CW → three-quarter circle (270° sweep) Start: (50,0) End: (0,50) sweeps downward-right
