Ondsel Lens Documentation

What is Ondsel Lens?

Ondsel Lens is an online vaulting and product data management (PDM) service for mechanical engineers and industrial designers. Lens will help you collaborate and iterate on your product designs, as well as showcase and share your personal work.

This documentation covers the administration of your own Ondsel Lens instance, managing projects, and using the FreeCAD addon.

What is Ondsel?

Ondsel was a company built around the free and open-source FreeCAD project. The company maintained three products: the Lens PDM, a FreeCAD flavour called Ondsel Engineering Service, and Lens Addon for connecting FreeCAD to Ondsel Lens.

The company shut down in November 2024 and transferred most of its intellectual property to the FreeCAD community.
