Model tree naming, Inventor export

I’m trying to show and hide items for a configurator on a model I’ve uploaded from Inventor but the model doesn’t seem to have the same structure, there’s no names and some parts have merged. How do I retain the model tree and naming?

Imported as STL and using importer, neither keep the structure.

Hi @Sjbaileyengineering ,
There is an undocumented API init toggle graph_optimizer. Here’s a link describing it: Searching for a good example of viewer api use: hide/show objects - #7 by mauricesvay
Perhaps that helps.
It’s also possible that sketchfab merges objects because they have the same material. You could try applying different materials to keep objects separate.
