Missing parts while importing CREO project in SOLIDWORKS

[imaks]

Hello

Could you help me?

I'm trying to import a customer assembly in SOLIDWORKS, but some parts are missing.

I tried to duplicate/mirror/pattern those parts, and then, those instances appears on SOLIDWORKS, but the original does not.

I've deleted all references and shown all layers.

Are there other options I should check to solve this problem?

Sorry, I can't share the assembly

Thank you in advance for your help.

Best Regards

Raúl
