How to make the mirror and actual mesh switch places I am working on a model from a video from Daniel Kreuter and I made a mistake and but the head outline and eye outline on the opposite side.
i want to know how i can make the mesh and the mirror side switch places
You can mirror a mesh or a part of it with the interactive mirror


set the pivot point to 3D cursor and place it correctly.
select the geometry you want to mirror
press CtrlM and one of the axis (x,y,z )
then press enter to commit
