Module sketch 

Sketch entities and constraints: plain f64 design data.

Points are the only entities with positions of their own; lines, arcs and splines reference points by PointId, so two curves that share an endpoint share the same point and stay connected by construction. Separately drawn points are joined with Constraint::Coincident, which the solver treats the same way (the two points become one set of variables), so connectivity is always structural — never inferred from two positions happening to be close.

Structs

ConstraintId

Key of Sketch::constraints.

Curve

CurveId

Key of Sketch::curves.

Point

PointId

Key of Sketch::points.

Sketch

A constraint sketch.

Enums

Constraint

The typical CAD sketch constraints. Distances and lengths are in sketch units, angles in radians.

CurveKind

Type Aliases

Positions

Every point’s [x, y], by PointId: the sketch’s own positions (Sketch::positions) or a rigid motion of them (see crate::ProfileLoop::to_nurbs).
