Failure (Boolean) error when bool one object

Hi, I’m using 1.90 on iPad M4, I have done many Boolean/trim/split operations on this current project, all of a sudden one of my objects

has started showing up this error. I’ve tried creating clones, creating new projects, restarted the app but it seems the issue won’t go away and this item remains impossible to either trim or bool with other objects…thoughts?

I get this from time to time. It’s typically my geometry that is messed up. It either has holes or hidden artifacts. I would try to isolate the problematic geometry by doing one at a time (it looks like you’re doing a good bit at once). They you can try to remesh the problematic one and see if that solves it. You can also click the 3 dots to the right of the selected object and click separate (this will expose any hidden artifacts). If it’s unsalvageable then hopefully you can recreate one of the pieces easy. Hope this helps.

Thank you, I will give it a go!
