Creation method#

There are two options for creating a Point In Curve node.#

  • The first way to create a Point In Curve 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.
    • pntInCrv
  • The second way is to select a Point In Curve node from the menu that opens from the top left.
    • Menu > Tool > Curve Analysis > Point In Curve

Steps#

  • Create a Point In Curve node.
  • Connect the closed curve with which you want to test containment to the first port.
  • Connect a point to the second port for the inclusion test.

After creating a node, connect the closed curve with which you want to test containment to the first port. Connect a point to the second port for the inclusion test. On the output port, you will get a number 0 = outside, 1 = coincident, 2 = inside, and a projected point on curve plane.
