   Construct nodes

The Construct category of the node palette.

Add these from Construct in the node menu. Each links to its own page.

  Midpoint - the point halfway between two points (pairs lists index-for-index).

  Divide - the n-1 points that split each A->B span into n equal pieces (Parts is editable; pairs lists index-for-index).

  Point on Curve - a point that rides along a curve; t is a fraction on a segment, an angle on a circle/arc, a distance along a ray/line.

  Point on Ellipse - a point on an ellipse (center + major + minor axis points) at a parametric angle.

  Nearest Point - the point in a set nearest a target location; picks the crossing you mean.

  Perpendicular Offset - a point offset perpendicular to an edge from a base point (a directed-rect / square corner).

  Vertices - the corner points of a region or curve, as points; wire to Preview to inspect corners or spot duplicates.

  Control Points - the Bézier control points of any cubic edges, as points (empty for line/arc edges).

  Perpendicular - an infinite line through a point, perpendicular to a line's direction.

  Parallel - an infinite line through a point, parallel to a line's direction.

  Perpendicular Bisector - the line perpendicular to segment AB through its midpoint.

  Angle Bisector - bisects an angle: vertex + two arms (points, or segments/rays/lines).

  Tangent - the tangent line from a point to a circle; the Side toggle picks which of the two.

  Tick - a tick mark on a line (short segment) or circle (short arc), centered on an anchor point.

  Select Outer Edges - the perimeter of the input: every edge with only one neighbor (interior/shared edges have two).

  Dimension: Linear - a linear dimension between two points (aligned / horizontal / vertical); the offset comes from a point, number, or field.

  Dimension: Angle - an angular dimension from a vertex and two arms; a Reflex toggle for the > 180 degrees angle.

  Dimension: Radial - a radius (or diameter) dimension from a center point and a rim point.

  Arrow Style - put arrowheads on a dimension, or bake them onto any open curve's ends; the dimension twin of Style.

  Explode - take a shape apart into the inputs of whatever made it; the sockets follow what is wired in.
