Importing 3dm file

Hi this may be a silly question but I’m new to Rhino and I imported a 3dm file with multiple layers and I can’t get them to display on the layout. I tried looking at user guides but I couldn’t find what was wrong. Thanks for your help.

Layers are used to organize the objects in a 3dm file.
Layouts are used to created print sheets of they model.
They are very different things.

Can you please describe the specific problem you’re trying to solve?

Sorry I guess I didn’t mean layouts I meant the grid screen. I imported the objects and they don’t show up on the grid. I can see the layers on the side bar and they are all on but the objects aren’t visible.

Hi - please run the Rhino SystemInfo command and post the result here.
