Creating Extremum Elements

You can create extremum elements (points, edges, or faces), that is elements at the minimum or maximum distance on a curve, a surface, or a pad, according to the given directions.

This task shows you how to:

Before you begin: Create a 3D shape containing a curve or a surface.

Create an Extremum Point on a Curve

You can create extremum point on a curve according to the given directions.

  1. From the Wireframe section of the action bar, click . Extremum
  2. In the Element box, select a curve.
  3. In the Direction 1 box, select the direction into which the extremum point must be identified.


  4. Click OK.


Create an Extremum Point on a Surface

You can create extremum point on a surface according to the given directions.

  1. Click Extremum .
  2. In the Element box, select a surface.


  3. In the Direction 1 box, select the direction into which the extremum must be identified.
  4. Click OK to create the extremum face.


    Important: Giving only one direction is not always enough. You need to give a second, and possibly a third direction depending on the expected result (face, edge or point) to indicate to the system in which direction you want to create the extremum element. These directions must not be identical.
  5. In the Direction 2 box, select the second direction.


  6. Click OK to create the extremum edge.


  7. In the Direction 3 box, select the third direction.


  8. Click OK.


Note: About the Min and Max options:
  • Max : according to a given direction the highest point on the curve is created.
  • Min : according to the same direction the lowest point on the curve is created.
