Creation method#

There are two options for creating a Surface Union node.#

  • The first way to create a Surface Union node using the search list, which is opened by double left-clicking in the workspace. You can write the name of the node you need, or words associated with this node.
    • union , boolean , su
  • The second way is to select a Surface Union node from the menu that opens from the top left.
    • Menu > Tool > Boolean Operation > Surface Union

Steps#

  • Create a Surface Union node.
  • Connect the first surface with which we want to union to the first port.
  • Connect the second surface that we want to union with the first surface.
  • Add a port for additional surfaces using the "add port" function in the port menu and connect other surfaces to the added ports.

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.
