Creating a Dart Function

You can create an intersection fillet and add a stiffener to a given shape. This shape is a surface and can be used as a contact zone.

Before you begin: Insert a surfacic functional set.

Defining Functional Properties
  1. From the Design section of the action bar, click Dart Function .
    The Dart Function Definition dialog box is displayed.
    Tip: This dialog box is interactive: it is dynamically updated each time you modify an option to represent how the chosen options will influence the result. The blue star near the option name means that it is a mandatory input.
  2. Select the Localization Point, i.e. the reference point where to create the dart. It is not mandatory that the localization point lies on the surface.
  3. Select the Guide Element to shape the dart such as to follow the guide surfaces. It can be a surface or a plane.


  4. Select the Dart Radius, i.e. the radius of the curved surface of the dart.
  5. Select the the Draft Angle, i.e. the angle between a lateral face and the Guide Surface. Draft angle governs the width of the dart feature. This angle is measured in a cross sectional plane to the curved (top) face of the dart. Following picture illustrates the section of the dart with the plane of dart angle measurement


  6. Select the Start Length and the End Length for the top and bottom lengths of the dart feature. These lengths are geodesic lengths, i.e. they are measured along the curve.


  7. Optional: Select the Intersection Fillet


  8. Click OK to create the dart.
    The element (identified as Dart Function) is added to the tree.
