Solidly

Third-Party Notices

Effective October 9, 2026

This page lists the third-party software included in the Solidly application for macOS, and carries the notices those licenses require. The Acknowledgements document inside the application bundle, which you can open from About Solidly, carries the same notices for the application.

This page also credits the 3D models shown in the videos on this website and in the App Store preview video, which are not part of the application and so are not in the bundled document. Credits for the website itself, including its typography and the software it is built with, are on the Attribution page.

Autodesk FBX

Such code is provided “as is” and Autodesk, Inc. disclaims any and all warranties, whether express or implied, including without limitation the implied warranties of merchantability, fitness for a particular purpose or non-infringement of third party rights.

OpenVDB

Solidly includes OpenVDB 10.1.0, which is licensed under the Mozilla Public License, version 2.0. A copy of that license is included in the Acknowledgements document in the application bundle. Solidly uses OpenVDB unmodified and links it as a separate library.

As the MPL requires, the source code for the version of OpenVDB included in Solidly is available on request. Write to support@getadversaria.com and we will send it to you, or point you at an identical copy, at no charge.

Open CASCADE Technology

Solidly makes use of facilities provided by the Open CASCADE Technology software (OCCT) 8.0.1, Copyright OPEN CASCADE SAS and Matra Datavision, to open STEP and IGES files. OCCT is licensed under the GNU Lesser General Public License, version 2.1, with the Open CASCADE exception, version 1.0. Both texts are included in the Acknowledgements document in the application bundle. Solidly uses OCCT unmodified and links it as separate, dynamically linked libraries.

The complete source code for the version of OCCT included in Solidly can be downloaded as occt-8.0.1.tar.gz, together with the script used to build it. We will also send both to you on request, at no charge, for at least three years after we last distribute a version of Solidly that contains OCCT. Write to support@getadversaria.com.

OCCT incorporates Delabella (Copyright GUMIX – Marcin Sokalski), MIT License; floating-point conversion code by David M. Gay (Copyright Lucent Technologies); Unicode conversion code (Copyright Unicode, Inc.); and the FlexLexer interface (Copyright The Regents of the University of California), BSD License.
