Measuring Distance Between Spot Fasteners  

• Measuring linear distance between two spot fasteners,
• Measuring curvilinear distance between two spot fasteners on a curve.

Measuring Linear Distance Between Two Spot Fasteners

1. Click Formula in the Knowledge toolbar.

   The Formulas dialog box is displayed.

2. Select Length as parameter type.

3. Click New Parameter of type, and edit the new parameter name as Distance.

4. Click Add Formula button or double-click Distance in the Parameter column.

   The Formula Editor : Distance dialog box is displayed.

5. Select Measures from the Dictionary column and double-click distance (BiW Spot, BiW Spot): Length from Members of Measures column.
   The selection field gets activated. In this case you can see distance(,) is displayed in the selection field.

6. Double-click the first fastener from the specification tree or the 3D geometry.

7. Similarly select the second fastener.

   Here select Joint Element.1 and Joint Element.3.

8. Click OK.
   The distance between the two spot fasteners is updated in the Distance parameter of the Formulas dialog box.

Measuring Curvilinear Distance Between Two Spot Fasteners on a Curve

1. Click Formula in the Knowledge toolbar.

   The Formulas dialog box is displayed.

2. Select Length as the parameter type.

3. Click New Parameter of type button, and edit the new parameter name as Curve Distance.

4. Click Add Formula or double-click Distance in the Parameter column.

   The Formula Editor : Curve Distance dialog box is displayed.

5. Select Measures from the Dictionary column and double-click LengthOnCurve (BiW Spot, BiW Spot): Length from Members of Measures column.
   The selection field gets activated. In this case you can see LengthOnCurve(,) is displayed in the selection field.

   To measure the length on a curve, the Spot Fasteners should be created using the Along Curve or From Curve on Surface options. If one of the spot fasteners is not created using these options an error message is displayed. Spot fasteners used in the LengthOnCurve formula must be defined on the same support curve. An error message is displayed if you try to measure the distance between two spot fasteners on two different curves.

6. Double-click the first spot fastener from specification tree or in the 3D view. Similarly select the second spot fastener.

   Here select Joint Element.8 and Joint Element.11.

7. Click OK.

   The distance between the two spot fasteners is updated in the Curve Distance parameter of the Formulas dialog box.
