I’m in need of a bit of help and advice. SU 2021 Pro crashes when I’m exporting to DWG, for some but not all files I try to export. The successful exports were for files of a 1.2MB and smaller. The unsuccessful exports were for files: 15.8MB and 16.2MB I reinstalled SU Version 21.1.331, but I get the same result. I’m on a rather new MacBook Pro: Model Identifier: MacBookPro18,3 Chip: Apple M1 Pro Total Number of Cores: 8 (6 performance and 2 efficiency) Memory: 16 GB System Firmware Version: 7459.141.1 OS

The info in log and crash files at the very beginning or at the end usually holds the most important lines. VM - Fault hit memory cashes probably means it ran out of (Virtual) memory. Might wanna try to split up the model in smaller ‘component’ pieces and export individually, or, shut down any other application running and dettach extra monitors if possible. ---

I’ve no idea as I’m not mac, but isn’t there something about compatibility of 2021 and the M1 chip. My vague memory tells me 2022 is the first to work natively with the M1. ---

Hi Box, I’ll look into that compatibility issue. Seems like MikeWayzovski could be onto something. The Bug Splat seems to indicate the process ran out of Virtual Memory. - Thanks, Fred ---

Hi Mike, I’ve done what you suggested and broken it into smaller parts and it seems to be working. Thanks for your help. Do you have any information on how to compress or clean up SketchUp files? I’ve got a huge one and it’s quite old as well. Thanks, Fred
