When adding a 3D Model to a Page in Documoto, Publishers must define a Part Number Regex during the Map to Model BOM step.
This article outlines what a Part Number Regex is, why it is currently required, and how to define one for your 3D CAD format.

What is a Part Number Regex?
A Part Number Regex is a search pattern that informs Documoto how to retrieve part numbers from CAD PMI properties (e.g. CAD files generated from SolidWorks, Inventor, etc.) in the 3D model.
Why is a Part Number Regex Required?
For the initial release of 3D Illustrations, defining the Part Number Regex is required so Documoto can match the correct part number to your BOM.
The Part Number Regex is temporary, early access requirement for 3D Illustrations.
