Put arrowheads on whatever flows through - the dimension twin of the Style node.

Inputs

  • Geometry (any): what to put heads on. A dimension gets its arrowhead set; any open curve gets heads baked onto its endpoints. Closed shapes (regions, circles) and points have no ends, so they pass straight through.
  • Head: the head style: Triangle (filled), Open (a plain V), or Tick (an architectural slash). A wired integer overrides by index.
  • Start (boolean) / End (boolean): turn the head on or off at each end.
  • Length (number, editable) / Width (number, editable): the head size, in millimeters. What you set is what draws and exports.

Outputs

  • Geometry (any): the same geometry, passed through with its heads set (on a dimension) or baked on (on an open curve). It's an inline modifier - it never alters the source geometry itself.

How it works

Like Style, Arrow Style sits inline in the wire. For a dimension it stamps the head onto the dimension, which the dimension's own draw and export then honor. For any other open curve it bakes the head as a real filled contour on the endpoint, oriented along the end's tangent - so exported arrows survive the trip into Illustrator, DXF, and whatever reads the file next.
