occt-import-js and the Open CASCADE Technology build inside it are both used unmodified, unlinked from our own code, and reached only through the interface occt-import-js publishes. We changed no source file in either project, and the WebAssembly binary we serve is the published one byte for byte. The LGPL-2.1 notices for both are served next to that binary, as license.occt-import-js.txt and license.occt.txt, and their source is available from github.com/kovacsv/occt-import-js and dev.opencascade.org. If you want the exact build we serve, or the build compiled into the viewer, ask us at 3dp@seabrightmechanical.com and we will send it.
One thing we cannot state cleanly. Open CASCADE publishes its own releases under LGPL-2.1 with the Open CASCADE Exception 1.0, but the license file shipped inside occt-import-js is the plain LGPL-2.1 text with no exception attached. This page used to claim the exception applied. We do not know that it does, so we have stopped saying so and treat the code as plain LGPL-2.1, which is the stricter reading. If you need this settled for your own compliance work, ask upstream rather than relying on this page.
