CPU Mode in Illustrator

Hello @Moonpepe,

Thanks for reaching out and sharing the details with our experts. Regarding the error message "Can't finish previewing. Could not complete the requested operation," this issue commonly occurs when there is a problem with the layers or objects within your Illustrator file. It's possible that a specific layer, clip group, compound clipping path, object, or group has become corrupted, causing the entire file to have issues.

To troubleshoot this problem and identify the problematic element, you can follow these steps:

• Isolate Layers: Start by isolating layers one by one. Delete all layers in your document except one, and then attempt to switch to GPU mode or preview your artwork. Continue this process for each layer, checking if the issue persists with each one.

• Delete Problematic Elements: Once you identify the problematic layer, group, or object, try deleting or recreating it. This might involve recreating the content from scratch or finding a backup if available.

• Save a Copy: Before making any changes, it's a good practice to save a copy of your file as a backup. This ensures you can revert to the original state if needed.

Remember to save your work regularly during this process and create backups to avoid any potential data loss. By isolating and addressing the problematic elements, you'll be able to resolve the issue and continue working on your Illustrator file without disruptions.

I hope these suggestions help you resolve the issue and improve the performance of your specific Illustrator file.

Best,

How much RAM (memory) do you have on your machine?

Does copy and paste (with Paste Remembers Layers checked in the Layers menu) parts into new document(s) work?
