Creation method#

There are two options for creating a Curve Proximity node.#

  • The first way to create a Curve Proximity 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.
    • px, proximity, distance
  • The second way is to select a Curve Proximity node from the menu that opens from the top left.
    • Menu > Tool > Curve Analysis > Curve Proximity

Steps#

  • Create a Curve Proximity node.
  • Connect the first curve to the "CrvA" input.
  • Connect the second curve to the "CrvB" input.

It is a node that finds the closest point between two input curves, and it outputs the closest point on the first curve, the closest point on the second curve and the distance between the two closest points.
