Introduction
Every solid starts as a flat drawing on a plane. A sketch holds that drawing: lines, arcs, circles and the other primitives, plus the constraints that say how they relate. A solver reads both and moves the geometry until every relationship holds. The solved profile is what Extrude, Revolve and the other 3D operations consume.
