Open Source Licences
Third-party software and fonts used in Dynamic Parts.
Dynamic Parts is built on open-source software. The component and typefaces below carry obligations beyond a simple mention, so their terms are set out individually; the notices for every other package are linked at the end.
Open CASCADE Technology (via opencascade.js)1.1.1
Copyright (c) Open CASCADE SAS
WebAssembly build: Copyright (c) Sebastian Alff and the opencascade.js contributors
GNU Lesser General Public License, version 2.1
We use this library to read STEP files in your browser. It is served unmodified as two static files, /occt/oc.js and /occt/oc.wasm, and loaded at runtime rather than compiled into our own code, so you are free to replace them with your own build. Complete source for the version we serve is on the project page below, and we will send a copy on request: info@dynamicparts.eu.
Fonts
Inter sets the interface, Stardos Stencil the wordmark, and the sketcher turns your label text into cut and engrave geometry using the faces listed below. All are under the SIL Open Font License 1.1; we serve the original files unmodified, with their copyright notices and the licence text alongside them: read the font licence.

Everything else is under permissive licences (MIT, BSD, ISC, Apache 2.0 and similar), which ask that the copyright notice and licence text travel with the software. The one exception, libvips, is LGPL, but it runs only on our servers and is never sent to your browser. We generate the notices from our lockfile on every build, so the list matches what we ship: read the full third-party notices. If we have missed an attribution, write to info@dynamicparts.eu.
