v0.6.1

Added

• OBJ export writes per-vertex colours, so soft colour borders survive in other renderers.

Fixed

• Release build: Cargo.lock now locks egui_bench from crates.io.

v0.5.3

Fixed

• Copy and paste work again and links open in the browser, which the egui 0.37 bump had broken.

v0.5.2

Fixed

• The web build compiles again on egui 0.37, and dropping a file on it reads the file asynchronously.

v0.5.1

Added

• gcad nest packs flat parts onto stock sheets with guillotine cuts, with mixed stock sizes, edged stock and a waste report, and a .gdwg operation for it.

Changed

• egui and eframe 0.37, which keeps the window running on Wayland when its workspace is hidden.

v0.5.0

Added

• Drawings: label points at faces, holes, edges or points and gcad places the text in a column
  beside the view where it overlaps nothing; hole labels write their own size, count and tap.

Changed

• Drawing PDFs are written with lopdf and their content streams are compressed.
• Drawing notes keep off the views.

v0.3.1

Added

• Heat transfer in flow simulations, and ducts.
• Early stop for flow runs that have settled.
• OpenFOAM heatsink comparison.
• Wind example, with CFD pictures in the README.

Changed

• Flow results are read asynchronously and stored as f16.
• Finer meshes for clash checks.

Fixed

• Release artifact path.

v0.2.0

Added

• Modelled ISO metric threads that run out into chamfers and countersinks.

Changed

• Fillets at corners and hole rims are built together, with exact end arcs and
  finer round fillets.
• Shells follow fillets.
• Exact lines and circles on boolean edges, and smooth STEP intersection curves.

Fixed

• Inside corners where three edges meet are rounded.
• Fillets that leave the solid unchanged fail instead of passing silently.
• Edge gaps are checked in STEP output.

v0.1.0

First release.

Added

• Line-per-operation part files (.gcad) with sketches, constraints, extrudes,
  revolves, sweeps, lofts, shells, drafts, ribs, holes, fillets, chamfers,
  patterns, mirrors, booleans, include, if and --set.
• Involute spur and internal gears.
• Assemblies (.gasm) with mates, joints, closed joint loops, couples,
  patterns, poses, exploded views and interference checks.
• Materials, mass and bills of materials.
• Export to STEP (with colours and assembly structure), STL, 3MF, OBJ and SVG
  drawings with section views, dimensions, parts lists and balloons.
• DXF and SVG import.
• egui viewer with a view cube, measuring, section plane, orthographic camera
  and joint sliders.
• Release builds, install script and agent skill.
