I have a noob script i created doing this! Basicly what i did was use the offset edge tool then i just deleted the original loop. Use the same offset value to get all 4 loops the same offset (duh). I Dont have My computer nearby right now but ill send the super basic script when i get home if i remember



polyDuplicateEdge -ch on -of 0.03;
dR_movePress;
doDelete;


change the value for how you like it. very simple yet useful

if anyone can pimp my script so that i can middle mouse the offset like the modelling tools that would be awesome
