Pass or Fail Results — 2D
If the edges/curves fail any of these checks, Creo Simulate does not create a contact.
If the edges/curves pass, Creo Simulate places a contact icon at the point where the edges/curves are closest to each other, oriented along the vector between the points of closest approach.
