SymTrz

Mirror And Symmetrize tools for 3D View.
Add-on by Berun

SymTrz is a real-time symmetrize preview tool designed to make directional symmetry faster and more intuitive. It helps artists instantly see which side will be mirrored, especially when working with rotated objects where the correct symmetrize direction can be unclear. Inspired by the symmetrize workflow of MeshMachine, SymTrz brings a smoother and more confident modeling experience.

This is a thing of beauty. Coming from other tools doing this, I like this implementation more. I only wish it could symmetrize in the direction you're flicking, which I feel is more intuitive. Also, the Mirror modifier should arguably have Clipping turned on by default as I think there's more times you want to clip vertices on the mirrored side.

Thanks for the suggestion, really appreciate it. The current direction was inspired by MeshMachine, but I’ll try to add an option in the preferences so you can choose to symmetrize based on the flick direction.

And yeah, I totally forgot about turning Clipping on by default for the Mirror modifier. Thanks for catching that.

[Your suggestion has been implemented , Thank you.]
