Crate geop_core_sketch 

2-D constraint sketches: points, lines, arcs, circles and splines, the typical CAD constraints between them, a BFGS solver, and conversion of the solved sketch into closed profiles for extrude and revolve.

• sketch: the entities and constraints (plain f64 design data).
• solve: Sketch::solve / Sketch::solve_with_drag.
• profile: Sketch::regions and ProfileLoop::to_nurbs.

Modules

bfgs

A dense BFGS minimizer with a backtracking (Armijo) line search.

dual

Forward-mode automatic differentiation for constraint residuals.

geometry

The geometry of sketch entities, generic over Scalar so every formula serves both the residuals (differentiated with crate::dual::Dual) and plain evaluation (profiles, rendering).

profile

Turning a solved sketch into profiles: closed loops of curves grouped into regions (an outer loop with its holes), and those loops into the NURBS curves that extrude and revolve consume.

sketch

Sketch entities and constraints: plain f64 design data.

solve

Solving a sketch: every constraint contributes residuals that are zero exactly when it holds, and crate::bfgs::minimize drives the sum of their squares to zero.
