Annotate faces with tolerances, threads, and colors directly on the 3D model. Share a link. Your factory sees exactly what you mean, no 2D drawings, no back-and-forth.
Click any surface on the 3D model. Assign a tolerance, thread spec, color, or note. Every annotation is bound to that face's geometry hash, not an index that breaks on re-export.
Three parallel injection strategies embed your annotations into the STEP file structure itself. Open the exported file in SolidWorks, Fusion, or any viewer, the metadata is there.
One link. No account required to view. Your factory, customer, contract reviewer, they click the face, they see the spec. Read-only. Nothing to install.
Drag and drop any STEP file. The geometry processes in seconds, hundreds of faces, automatically fingerprinted and ready to annotate.
Click any surface in the 3D viewer. Set tolerances, thread types, colors. Use the heat map to visualize your tolerance distribution across the whole part.
Export an annotated STEP file with metadata baked in. Or copy a share link, anyone with it can view the annotated model in a browser, no account needed.
For engineers evaluating the workflow. Full functionality, limited scale.
For hardware engineers sending parts to factories weekly.
For companies managing many parts across multiple suppliers.
"Active projects" = STEP files you can work on at the same time. Archive a project to free a slot, share links stay active.
