I'm working with objects with multiple paths in Illustrator. I selected all my paths in one object, moved them slightly, and most of the paths went invisible. They still exist: I can select them, but not see them except for the selected outlines.
Command Z reverts the last step, but does not reverse the invizibility
I reverted to my most recent saved version, tried manipulating those paths - no problem. Then I transform>reflected the whole object, and whoosh, most of the paths are gone again.
Reverted and tried again, could manipulate for a while, and then was changing one path's shape, and it disappeared.
Start by turninmg off GPU acceleration in the preferences and then take the usual steps - updating the graphics driver etc..
No dice. I'm on a Mac and have the latest OS, so the graphics drivers should be up to date. I've tried turning off GPU acceleration, and the problem still happens whenever I reflect the object - always the same lines going invisible. So I don't think it's the graphics driver.
Please show a screenshot of layers and appearance panel with thw objects selected.
Also it will help to see a screenshot of the whole artwork with selected invisible objects.
Can you also try and copy them to a new file and do the reflection there? Does that work?
Do you know how to use the layers panel to inspect your file?
