Hi, I am prepping an Architectural model for prototyping and have run into a problem with the windows, currently they have been extruded out from the surface, I need to inset them all from the surface. I have resigned myself to making a selection of all the windows ( several hundred ) , but i can't for the life of me work out how to set them all back locally. Essentially i need the functionality you would get if you were to Extrude the selected faces but without adding any faces. I am using Maya 2009 Please help, need to get this finished ASAP. Thanks in advance!
