The radius of a circle or arc (exact), or a segment's length, pulled out as a number.
Category: Data | Add menu: Data > Radius
- Geometry (any): the circle, arc, segment, or points to measure.
- Radius (number): the radius (or segment length) as a number, in mm.
Radius pulls a length out of whatever geometry you feed it, using the same rule as a Circle's Radius input:
- A circle or arc: its exact radius.
- A segment, or two points: the distance between the ends.
- Three or more points: their average distance from the centroid.
