Subtract?
 

Hello :)
I just wanted to know how do i subtract from an object?
say ive got a square on 1 layer and i want to cut a smaller
square out of tha object which is on another layer. How do i
do it?

thanks for the help

Construct tab, Boolean operation, click subtract. Make sure you have the object you want to act as the knife in the background layer. I'm assuming you know how to setup a foreground and background layer.
