I normally dont write much on this blog, but this time I want to write about the mirror tool. most maya users like to model one side of the mesh then delete half. It works fine but very tedious. I found a work around, which is the mirror cut tool.
1) select mesh, run mirror cut option
2) Uncheck the merge with the original and then apply
3)What ever edits you make to one side will be transferred over to the mirror side.
