# Attribution

Every non-code asset in this repository (images, icons, fonts, example parts) is listed here with
its author, source and licence. `cargo xtask assets` (part of `cargo xtask ci`) fails if an asset
file is missing from this table.

**Policy (mandatory):** SolveCraft contains **no Autodesk iconography, images, artwork, fonts,
templates, materials or help text.** Every asset is original work by SolveCraft contributors or
third-party material under an open licence. Screenshots of Autodesk software are never committed.

Generated-in-code assets are original and have no file to list:
- the UI icon set (`crates/ui-egui/src/icons.rs`);
- the view cube, navigation bar and timeline glyphs (`crates/ui-egui/src/viewport.rs`,
  `crates/ui-egui/src/timeline.rs`).
