Creation method

[comment]: <> ()

There are two options for creating a Region Glue node.

  • The first way to create a Region Glue 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.
    • glue , boolean , crv , assemble
  • The second way is to select a Region Glue node from the menu that opens from the top left.
    • Menu > Tool > Boolean Operation > Region Glue

Steps

  • Create a Region Glue node.
  • Connect the first region with which we want to union to the first port.
  • Connect the second region that we want to union with the first region.
  • Add a port for additional regions using the "add port" function in the port menu and connect other regions to the added ports.
  • Optionally set the Glue Type parameter (GlueShift for touching faces, GlueFull for exact match - fastest).

After creating a node, to the first port, connect the first region with which we want to union other regions, connect the second region to the second port with which we want to union the first region connected to the first port. For more than two regions, you need to add ports using the "add port" function in the port menu and connect other regions to these ports.

The Region Glue operation is optimized for touching/non-penetrating shapes. It uses glue mode to skip heavy intersection calculations when curves only touch each other, making it faster for assembling operations.

  • Glue Type GlueShift: Use when shapes touch and faces might overlap/coincide. It shifts shapes slightly to avoid numerical instability.
  • Glue Type GlueFull: Use when faces match exactly (vertex-to-vertex). This is the fastest mode.

On the output port, we will get the result of the union with glue optimization.
