Platform: iPad  
NOMAD APP VERSION: 2.8

I was using the trim tool to carve silhouettes and ran across a weird bug where the mesh mostly disappears, instead of following the Bézier curves.

Attempted workarounds (failed)  
Cloning the object  
Close holes & make manifold  
Remesh (voxel)  
Changing projection angle  
Changing the Bézier curves  
Turning off flip did produce the correct results, if that info is useful

I’m including the file in hopes that it will help find the bug.  
[The file](https://drive.google.com/file/d/1x1aG90NtrSV1M_bBBKgP6xvyTAh5IH2b/view?usp=drivesdk)  
To reproduce the bug with the file simply activate the trim tool with flip enabled, and using Bézier, and confirm once you’re happy with the shape.

Cheers

Did you disable symmetry?

I didn’t even think of that, I’m such an idiot. 😅

Don’t sweat it at all, you’re definitely not an idiot! Symmetry trips up literally everyone at some point when using the trim or boolean tools. It tries to calculate the cut on both sides simultaneously, fights with the center line, and just deletes the geometry. Glad you figured it out!
