Creation method#

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

  • The first way to create a Solid 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 , crv , ru
  • The second way is to select a Solid Union node from the menu that opens from the top left.
    • Menu > Tool > Boolean Operation > Solid Union

Steps#

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

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