  1. Click the I_FormulaP2.gif (164 bytes) icon. The Formulas dialog box is displayed.

  2. In the parameter list, select the PartBody\Sketch.1\Radius.1\Radius item, then click Add Formula. The Formula editor displays.

The icon located on the right is simply a rubber you can use to erase the formula.

 

  1. Enter the 2 * PartBody\Hole.1\Diameter relation.

  2. Click OK in the Formula Editor once you have typed your relation. The Formula.1 relation is added to the specification tree.
    In the parameter list of the dialog box, a formula is now associated with the pad radius.

  3. In the parameter list, select the PadLength item, click Add Formula to create the formula below:

    PadLength = PartBody\Pad.1\FirstLimit\Length  + PartBody\Pad.1\SecondLimit\Length

    In the parameter list, the Formula.2 relation is now associated with the PadLength user parameter. In the specification tree, PadLength is also displayed with the value resulting from Formula.2. This is now what you should see in the specification tree under "Relations":

  4. Click OK in the Formulas dialog box to terminate this task. Keep your document open and proceed to the next task.
