Creation method#

There are two options for creating a Planar node.#

  • The first way to create a Planar 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.
    • pln , is , curve plane
  • The second way is to select a Planar node from the menu that opens from the top left.
    • Menu > Tool > Curve Analysis > Planar

Steps#

  • Create a Planar node.
  • Connect the curve for planarity test, to the port.

After creating the node, connect the curve to the port for a coplanarity test. The first output will be a boolean ( True/False) indicating whether the curve is coplanar or not, True if the curve is coplanar. The second output returns the plane if the curve is coplanar. Planar node is useful in situations where you want to check if a curve is coplanar before applying certain operations, or if you want to filter out non-planar curves in a list of inputs.
