That depends on the PCBlib has 3D model or not.

Before updating all components had 3D models but after updating the models are loading randomly and not fully.

please export your PCB and send to [support@easyeda.com](mailto:support@easyeda.com) that seems some 3D models loading fail, when you waiting it few second does it will loading all?

Hi, I have the same behaviour: trying to generate the 3D model with the same PCB (there are all the models), the componets appear and disappear randomly at aevery round. BR antogar

Hi, I've got the same issue.

Hi, so on my board always random component is showing 

@UserSupport hi all i have a same problem. just some 3d models are displayed. this problem was appeared two days ago (this show on the screenshot) 

Same problem here . My own board. After Updating the PCB most of the comonents are loosing 3D Mapping

Also the same problem appears when I clone my own PCB in the same project. Some componets loosing the 3D mapping and do not appear in the 3D Simulation
