SketchUp 2018 to Layout not responding

I’m having trouble sending a SketchUp scene to Layout. My total size of my SketchUp model is 560Mb. Could the size of my model causing SketchUp not to respond to sending a scene to Layout?

Yes. That’s very likely the problem. Have you purged unused stuff from the SketchUp model? Have you already sent this SketchUp file to LayOut?

I restarted the software and got SU to LO to work. I don’t know how to purge, but will look in the software. Should be able to see the purge function. Thanks, DH

I found purge. Thanks! DH

Window>Model Info>Statistics>Purge Unused.

Did it reduce the file size by much?
