Surface
Result outlines of boolean union
After creating a node, to the first port, connect the first surface with which we want to union other surfaces, connect the second surface to the second port with which we want to union the first surface connected to the first port. For more than two surfaces, you need to add ports using the "add port" function in the port menu and connect other surfaces to these ports. On the output port, we will get the result of the union.
