HarmonyWare provides NURBS-based geometry translator tools handling the STEP, IGES, VDAFS, STL, SAT (Acis (TM)), Parasolid XT, and openNURBS (Rhino (TM)) file formats. We have libraries to provide interfaces for these formats to the NLib, TSLib, POPLib, SOLIDS++, TSNLib, and SMLib geometry engines. We also offer an interface to DATAKIT's CrossCAD/Ware SDK which allows you to import from CATIA v4-v6, UG, Parasolid, SolidWorks, SolidEdge, JUT, ProE, and more.

(Finally starting the major revamp this web page has needed for at least a decade!)

• October 2nd, 2026: Anticipated HWLibs 2.9.3 release week of October 5th.
• July 18th, 2026: Beginning to roll out the HWLibs 2.9.2 release. If you think you should be getting a copy of this release and you haven't by July 24th, please contact us. For an overview of what is in this new release, please see the README.
• January 24th, 2026: Well, HWLibs 3.0 is taking much longer than expected. However, it's much closer to done now, and we hope to have the IGES and STEP translators up and running on the new system sometime in the next couple of months.
• July 25th, 2024: The sale of NLib and SMLib to NVIDIA created a number of legal and logistical challenges that have prevented us from releasing a new version of HWLibs since 2022. We are hard at work on HWLibs 3.0, with the goal of eliminating the low-level code and translators from any dependence on NLib or SMLib, as well as updating the source code to work well with C++14 and beyond. The current goal is to have an "alpha" version of this ready for release in the fall.
• November 8th, 2022: 2.1.9 release. E-mails announcing this went out yesterday and today, if you think you should get one and did not, please check your spam mail folder and then contact us. This release includes support for the latest version of SOLIDS++, basic STEP export to APs 214 and 242, and the usual batch of small enhancements and bug fixes. See the changelog for details.
• June 15th, 2022: HarmonyWare now directly handles HWLibs support for the various geometry engines formerly marketed by Solid Modeling Solutions. This page finally starts to get an update.
• December 15th, 2021: 2.1.8 release. Includes support for DATAKIT V2021.4 and SMLib 8.12.0 and the usual batch of small enhancements and bug fixes. See the changelog for details.

• October 2026: 2.9.3 release.
• December 2026: 2.9.4 release.
