MeshLab is an open source system for processing and editing 3D triangular meshes. It provides a set of tools for editing, cleaning, healing, inspecting, rendering, texturing and converting meshes. It offers features for processing raw data produced by 3D digitization tools/devices and for preparing models for 3D printing.
When your mesh is ready to upload, go to Filters → Smoothing, Fairing and Deformation → Export to Sketchfab. A pop-up will appear for you. You'll want to enter your API Token in the Sketch Fab Code field, as well as a title, description, and appropriate tags.
You can also mark this export as Private (if you have Pro membership on Sketchfab) or Publish if you want to skip Draft Mode and share your model with the Sketchfab community.
In most cases, we would recommend you keep Auto Rotate enabled.
Then, click Apply and your model will be uploaded to your account.
