Arc
Arc polyline on the XY plane — open Path between startDeg and endDeg. Use it for partial circles, fillets, and curve-stitching with Join Curves.
Node
Interactive preview is available in the interactive reader.
Sockets
center (in)- Vector3. Arc centre (default [0, 0, 0]).
radius (in)- Float. Arc radius (default 10).
path (out)- Path — arc polyline on the XY plane, Z = center.z.
Parameters
Start °- Start angle in degrees (measured counter-clockwise from +X). Default: 0.
End °- End angle. Default: 180.
Segments- Number of polyline segments. Default: 32.
How It Works
The arc is sampled at segments + 1 positions between startDeg and endDeg. A full 360° arc produces an open polyline where the first and last points coincide; if you want a closed loop, use the Circle node instead — it skips the duplicate endpoint.
