You might have found yourself struggling with the selections in maya
specially during the process of unwrapping . You make selection and it just disappears and you don't know how to bring it back without using undo command.
Heres a quick way to do it.
Make the desired Selection
Go to Create-> sets-> quick select set
A pop up will appear asking you to name your selection set.
Now don't bother if you lose your section. Whenever you lose it you can go to
Edit-> Quick select set-> The name which you have given(In my case its Faces)
Thats all for now. i'll be back next time with much more tricks of MAYA
see you soon ;)
