Repeating Spot Fasteners

You can repeat spots along a selected curve using a created spot point as the reference.

Before you begin:

  • A Creating a Spot has been created.

  • This capability is only available with the On Curve and Point On Parallel Curve On Surface location methods.

  1. Double-click the spot in the specification tree to display the Spot Fastener Definition dialog box.

  2. Select the Location Method in drop-down list.

    Here, select On curve.

  3. Select the Repeat object after OK check box.



  4. In the On Curve Location dialog box, select the Curve and the Reference Point.

  5. Click OK.

    The BiW Fastener Repetition dialog box appears:



    It shows:


    • the Reference Fastener referring to the currently created spot.

    • the

      Ref. End Point being the extremity of the curve by default. You can choose the other extremity by clicking Extremity as well as selecting a point or a spot point.

  6. Define the Parameters:


    • Instance(s): number of instances to be created. The distance between two successive points is automatically computed, spots are equidistant and the last repeated spot is positioned on the curve end point. The spacing between two successive spots is computed.


      • Define the number of instances to be created in the Instances field.
      • You can specify a Spacing To Ref. End Point to define the working curve length: enter a spacing value to specify the end of the working curve length. The pitch is automatically updated.
      • Clear the With end point option if you do not want the last created spot to be located on the end point. It is not mandatory that the end point be located on the curve end.



        Instances = 4 Spacing To Ref. End Point = 10mm With end point option selected

    • Pitch: spacing value between two consecutive spots. The number of instances created do not exceed the working curve length.


      • Define the number of spacing value in the Pitch field.
      • You can specify a Spacing To Ref. End Point to define the working curve length: enter a spacing value to specify the end of the working curve length.
      • Select the Best Fit Pitch And Instance(s) option to automatically compute the best pitch and the corresponding spot instances. It lets you optimize the distribution of the created spots on the working curve length. A new pitch is computed to comply with both Spacing To Ref. End Point and Best Fit Pitch And Instance(s) defined values. The With end point option appears and is selected by default. It is not mandatory that the end point be located on the curve.


      • Clear the With end point option if you do not want the last created spot to be located on the end point.

        Pitch = 50mm Spacing To Ref. End Point = 80mm With Best Fit Pitch And Instance(s) options cleared

    • Instances & Pitch: number of instances and spacing value. Spots are created towards the end point and can be created after the end point.




      • Define the number of instances to be created in the Instances field.
      • Define the number of spacing value in the Pitch field.

        Instances = 6 Pitch = 30mm

  7. Click OK to validate the repetition.
