When I load SCS files using `Model.loadSubtreeFromScsXmlBuffer` , I get duplicate nodes in the tree. How can I fix this?

Any insights or suggestions would be appreciated!

Hello @18234083588,

It looks like you are following a shattered workflow. In which case, the hierarchy will include separate nodes representing _instances_ (such as `NodeType.PartInstance` and `NodeType.BodyInstance`). This is normal in shattered workflow.

If you want to have a flatter tree hierarchy, a monolithic workflow would probably work better.

Thanks,  
Tino
