Construction axes, points and planes from model geometry (SOLID ▸ CONSTRUCT): axes through a cylinder/cone/torus, perpendicular to a face at a point, through two planes, two points or an edge; points at a vertex, through two edges, three planes, at the centre of a circle/sphere/torus, at an edge and a plane, along a path; midplane, planes through two edges or three points, tangent to a face, along a path. References (doc::construct::GeoRef) keep picked faces and edges by persistent name and resolve on each evaluation (they follow the model); results live in ModelState.construct, in the component's frame; view::construction_axes/points/planes for the viewport; kernel::face_surface for a face's analytic surface
