A circular arc that starts at Point 1, passes through Point 2 and ends at Point 3. Three points in a line give a straight polyline instead.
Start point, from a wire; replaces the typed value.
Middle point, from a wire; replaces the typed value.
End point, from a wire; replaces the typed value.
Values the block gives besides its output. The editor lists them under Properties, and an input can read one by reference.
Where the curve begins.
Where the curve ends.
The curve's unit direction at its start.
The curve's unit direction at its end.
Unit vector along the straight chord from start to end.
Length measured along the curve.
The center of the curve's bounding box.
The axis-aligned extent of the curve.
Distance to the curve as a field, zero on the curve.
At each point, how far along the curve its nearest curve point lies (computed on the CPU only).
The display name of the node that made the curve.
The same curve, running from end to start.
How far the arc sweeps around its center, in degrees.
Center of the circle the arc lies on.
Unit normal of the plane the arc lies in.
Radius of the circle the arc lies on.
True when the arc sweeps a full circle.
