There are two options for creating a Control Points node.

  • The first way to create a Control Points 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.
    • controlPoints , cp
  • The second way is to select a Control Points node from the menu that opens from the top left.
    • Menu > Tool > Curve Analysis > Control Points

Steps

  • Create a Control Points node.
  • Connect the curve whose control points we want to find to the port.

After creating a node, connect the curve whose control points we want to find to the port. On the output port you will receive control points, knots and weights.
