Version Control
Every file upload is stored as a numbered version with a commit message, timestamp, and author. Scroll back through your entire history and restore any previous version with one click. No more overwriting critical work.
When you're actively editing a file, lock it so teammates know not to upload conflicting changes. Locks are visible across your whole team and can be released when you're done.
A complete, immutable log of every action taken on every file and repository. Know exactly who uploaded what, when they did it, and what they changed. Essential for regulated industries.
Collaboration
Structure your workspace the way your organization actually works. Create an organization, build teams within it, and assign repositories to specific teams with granular access control.
Request a formal review from a teammate before a design is considered approved. Reviewers can approve, request changes, or leave detailed feedback — all tracked within the platform.
Leave comments directly on a specific file version or on a saved 3D view. Have threaded conversations, resolve comments when addressed, and keep all feedback alongside the file it relates to.
Viewing & Sharing
Open any STL file and view a fully interactive 3D model right in your browser. No plugins, no downloads, no software licenses required. Rotate, zoom, and inspect geometry from any device.
Generate a public link for any file version and share it with clients, vendors, or stakeholders — even if they don't have a Lummicron account. Revoke access at any time.
Organize files in repositories just like you would in a project folder — but with structure. Group related files, set privacy levels, and manage access from one central place.
