Check these when you upgrade

• Breaking: three body classes. Make bodies with new Wire(kind, params), new Solid(kind, params) and new Sheet(OG_OPERATION_SWEEP, params). The 2.0 classes such as Cuboid, Polygon, Sweep and AnalyticSolid are gone.
• Breaking: arrays, not Vector3. Points and vectors are [x, y, z].
• Breaking: move with transform. Setting position, rotation or scale is reverted.
• Breaking: start the kernel first. Await OpenGeometry.create(input, options) once. workerURL goes in the second argument.
• Breaking: 2D calls are statics. Use OpenGeometry.booleanRegions2D, OpenGeometry.offsetRingVariable and the others. Offsets return line and arc edges.
• Breaking: OpenGeometry.exportIfcBody(solid) replaces solid.prepareIfcExchange().
• Breaking: OGError. Catch it and branch on code.
• Breaking: the shell hollows in place. Use solid.operate(OG_OPERATION_SHELL, { thickness }).
• Breaking: display follows drawing. A body gets its mesh when it is drawn or walked. Its surface and outline meshes are static: call updateMatrix() after you move them yourself.
• Smooth edges. Outlines leave out smooth edges, and faceted curves shade smooth. Set appearance.smoothAngle to 0 for the 2.0 look.
• Removed: IFC file text, STL and PDF export, projection, loft, public triangulation, and curves other than lines, circles, arcs and polylines, such as the elliptical arc. 3.0 has no spline, no ellipse and no elliptical arc. The wedge and the 2.0 Curve class are gone too. Build a wedge as a five-face OG_PRIMITIVE_POLYHEDRON, and a 2.0 Curve as an OG_PRIMITIVE_POLYLINE wire through its points.

​

Added

• Solid primitives: cuboid, cylinder, cylinder sector, sphere, cone, torus and polyhedron. Wire primitives: rectangle, circle, polyline, profile and arc. See Primitives.
• Extrude, sweep and revolve, with exact arcs.
• Booleans with up to a hundred tools, and shell.
• Rebuild and mirror, assemblies, copies and instances, and marks and transactions.
• Queries: bounds, B-rep, face normals, point classification, measured volume and area, validity.
• Display for Three.js, picking and host-drawn layers.
• STEP export and the IFC exchange body.
• Exact curved insets: OpenGeometry.insetCurvedRegion2D and OpenGeometry.offsetCurvedRingVariable. See Regions and offsets.
• Solid primitives: slot prism, rounded box and pipe segment. See Primitives.
• Polysolid. OG_PRIMITIVE_POLYSOLID makes a solid wall of constant width and height along a path of straight legs and tangent arcs, justified 'centre', 'left' or 'right', with mitred corners. A joint where an arc meets a segment at an angle throws InvalidParameter that names the joint. See Primitives.
• Wire primitives: regular polygon, slot and rounded rectangle. See Primitives.

​

Fixed

• A circular hole away from the profile centre extrudes.
• Offset corners are exact arcs.
• A point inside one of two touching solids of a body is Inside.
