Everything you need to get your team up and running with Lummicron. Start with the quick-start guide or jump to a specific topic.
Lummicron requires no software installation. Everything runs in your browser. Create an account, make a repository, and upload your first file — it takes under two minutes.
The dashboard shows all your repositories at a glance. Each card displays the repo name, privacy level, last updated time, and a quick link to upload a new file.
Sign up with your email address to get started.
Think of a repository as a project folder. Name it after your project or part — e.g., "Engine Bracket" or "Frame Assembly". Set it to Private or Public.
Drag and drop a DWG, DXF, or STL file into your new repository. Add a version message (like "Initial design") to describe what this version represents.
Go to Settings → Members and invite teammates by email. Assign roles to control who can upload, who can review, and who has admin access.
A repository is the top-level container for a design project. It holds all related files, their version histories, comments, and activity logs.
The repository view shows all files in a folder structure on the left, with a version sidebar on the right. Click any file to see its full version history and open the 3D viewer.
Anyone with the link can view files. Good for sharing work with clients or vendors.
Only invited members of your organization can access. Default for internal work.
Files can be organized in folders within a repository. Use folders to group assemblies or design stages.
Change privacy, rename, manage member access, or delete a repository from the Settings tab.
Every time you upload a file, Lummicron stores it as a new version. Versions are numbered sequentially (v1, v2, v3…) and each one is permanent — you can never accidentally overwrite history.
The version panel shows each upload with its version number, the message you wrote, who uploaded it, and when. Click any version to switch the viewer and file preview to that point in time.
Lummicron includes a full WebGL-powered 3D viewer for STL files. No software installation needed — models render directly in your browser on any device.
The 3D viewer gives you orbit, pan, and zoom controls. Toggle wireframe mode to inspect geometry. Save named views to bookmark specific camera angles for review.
Saved views preserve the exact camera position, rotation, and zoom level. Share a specific view with a teammate to make sure everyone is looking at the same part of the model.
Organizations are the top-level workspace for a company or group. Within an organization, you can create teams — each with their own set of members and repository access permissions.
The organization settings page shows every member, their role, and which teams they belong to. Invite new members by email. Admins can update roles or remove access at any time.
Full control. Can manage billing, delete the organization, and promote others to Owner.
Manage members and teams. Grant and revoke repository access. Cannot delete the organization.
Access to repositories they are explicitly granted. Standard upload and review capabilities.
Read-only access to specific repositories. Cannot upload files or leave comments by default.
When you're actively editing a file, lock it to signal to your team that a new version is in progress. Locked files show a visible indicator to all members of the repository.
Locked files display who locked them and when, so teammates know to wait or coordinate. When you finish editing and upload the new version, the lock is released automatically.
Organization Owners and Admins can release a lock held by another user. Use this if a teammate is unavailable and the file needs to be updated urgently.
Use review requests to formally ask a teammate to review a specific version of a file. This creates a trackable approval workflow — similar to a pull request in software engineering.
The review panel shows the reviewer, the version under review, the current status (pending, approved, or changes requested), and any comments left during the review.
Review has been requested. The reviewer has been notified.
Reviewer approved this version. The design is cleared to proceed.
Reviewer left feedback. Uploader should address comments and re-upload.
Every action in Lummicron is logged — uploads, downloads, comments, reviews, share link creation, and membership changes. The audit trail is append-only and cannot be edited.
Filter the audit log by user, action type, or date range. Each entry shows the actor, the action, the affected file or resource, and the exact timestamp.
The audit trail supports regulatory and quality management requirements by providing a complete, timestamped record of who changed what and when. Export data is available on Team and Enterprise plans.
Our team is happy to answer questions, walk you through anything, or hear your feedback.

Comments
Leave comments on any file version or on a saved 3D view. Comments support threaded replies, so conversations stay organized and in context.
Each comment is anchored to a specific version. Mark a comment as resolved once it's been addressed — resolved comments are collapsed but never deleted, preserving the full history of feedback.
