Creation method#

There are two options for creating a Tangent Lines (Ex) node.#

  • The first way to create a Tangent Lines (Ex) node is 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.
    • ln , tanEx
  • The second way is to select a Tangent Lines (Ex) node from the menu that opens from the top left.
    • Menu > Tool > Primitive curves > Tangent Lines (Ex)

Steps#

  • Create a Tangent Lines (Ex) node.
  • Connect the first base circle to the first port.
  • Connect the second base circle to the second port.

After creating the node, connect the first base circle to the first port, and the second base circle to the second port. On the output ports, you will receive the primary and secondary exterior tangents.
