Copy the vanilla engine from dwg-dxf-viewer-sample verbatim (#1): - src/engine/viewer2d/* (Viewer2D.js incl. the 2.5D view, parsers, acadrust-dwg WASM, cadSpaces, slugText, linParser/linData, fixDwgKoreanText, ...) - src/engine/{layerPanel,panelUtils,propertyInspector,optionsStore}.ts The relative layout is kept (engine/viewer2d next to the panel files), so not even import paths changed; `diff -r --strip-trailing-cr` against the sample is empty. public/ (NanumGothic, samples, licenses, module map) is copied as is.

# Third-party notices
|
|
|
|
This viewer bundles third-party code. The notices below apply to the source
|
|
tree **and** to the built site (`dist2/`, deployed at
|
|
`https://dwg-dxf-viewer-sample.pages.dev/`), because the build embeds the
|
|
components listed here.
|
|
|
|
Served copies of the license texts live under
|
|
[`public/licenses/`](./public/licenses/) → `/licenses/…` on the deployed site.

## acadrust 0.4.1 — Mozilla Public License 2.0 — **MODIFIED**
|
|
|
|
| | |
|
|
|---|---|
|
|
| Component | `acadrust` (DWG/DXF parser, Rust) |
|
|
| Version | 0.4.1 |
|
|
| License | MPL-2.0 — full text: [`public/licenses/acadrust-MPL-2.0.txt`](./public/licenses/acadrust-MPL-2.0.txt) (`/licenses/acadrust-MPL-2.0.txt`) |
|
|
| Upstream | https://github.com/hakanaktt/acadrust · https://crates.io/crates/acadrust/0.4.1 |
|
|
| Upstream commit | `f249c2f816acf36ee51cd5533716bdd443c2517e` (from the crate's `.cargo_vcs_info.json`) |
|
|
| Author | Hakan AK |
|
|
| Shipped as | compiled into `assets/acadrust_dwg_bg-*.wasm` (Executable Form) |
|
|
|
|
**This copy is modified.** One file differs from the published crate:
|
|
|
|
```
|
|
src/io/dwg/dwg_stream_readers/object_reader/entities.rs (read_mesh array-count bounds)
|
|
```
|
|
|
|
The modification bounds `read_mesh`'s array counts by the bits remaining in the
|
|
object stream instead of the blanket 100 000-item guard, which truncated and
|
|
thereby corrupted large SubD meshes.
|
|
|
|
### How to obtain the Source Code Form (MPL-2.0 §3.2)
|
|
|
|
1. Get the unmodified crate source — `cargo vendor`, or
|
|
`https://crates.io/api/v1/crates/acadrust/0.4.1/download`, or the upstream
|
|
commit above.
|
|
2. Apply [`public/licenses/acadrust-0.4.1-read_mesh.patch`](./public/licenses/acadrust-0.4.1-read_mesh.patch)
|
|
(`/licenses/acadrust-0.4.1-read_mesh.patch` on the deployed site):
|
|
|
|
```bash
|
|
tar xf acadrust-0.4.1.crate && cd acadrust-0.4.1
|
|
patch -p1 < acadrust-0.4.1-read_mesh.patch
|
|
```
|
|
|
|
The result is the exact Source Code Form of the acadrust code compiled into the
|
|
shipped `.wasm`. Both the original and the modified file remain under MPL-2.0.
|

## dwg-wasm — MIT
|
|
|
|
The wasm-bindgen wrapper that turns acadrust output into this viewer's
|
|
`parseResult` (`hmwebviewer/rust/dwg-wasm/`). Our own code, MIT. MPL-2.0 §3.3
|
|
permits distributing this Larger Work under different terms as long as the
|
|
MPL-covered files above keep their license — which they do.
