Hello,
So, the problem is the following.
I have to put complex form pad on my PCB

The pad boundaries are: Board OUTLINE and the 3 sides of the black rectangle.
I am going to put the just SQUARE PAD on the top of this black rectangle and suppose that after cutting the PCB on Board Outline I will get just what I need.
Am I right? Can somebody confirm this logic.?
Thank YOU in advance
P.S. If could not explain which form I need for my PAD, below is the clarification. YELLOW should be the PAD
