STL Diff Documentation

Learn how to share STEP files, collaborate on 3D model revisions, compare changes and convert STEP to STL in Projects.

A place to develop models together

STL Diff connects the editable source, the next revision and a visual comparison. Edit in your CAD tool, then bring the new version back so collaborators can see what changed. You can start with a free Project or use the standalone comparison without an account.

Today you bring your own collaborators through invitations and explicit links. There is no public community catalogue yet, and uploading a Project does not automatically publish its originals.

GUIDE 01

Share STEP files and editable originals

Keep the source with each revision and choose who can download it.

GUIDE 03

Convert STEP to STL for free in Projects

Automatically generate a printable mesh while retaining the editable STEP with its revision.

Browser agents & API

Experimental WebMCP

In a browser with experimental WebMCP support enabled, an agent can inspect comparison state, select Project revisions, read review status and start existing exports. Creating a Project review link still requires confirmation in Share for review. Project permissions and plan limits apply. Names and comparison statistics may be visible to your chosen agent; model bytes and management tokens are not included in tool results. Browsers without this support keep the normal interface.
