Defining Rib Thickness as a Parameter

The thicker the rib, the more resistant the knob is to torsional loading. However, thicker ribs increase the mass of the model. You define the rib thickness as a parameter and use it as a variable to find the optimal dimension.

  1. On the Optimize study tab, in the Variables section, from the Click here to add Variables list, select Add Parameter.
  2. On a blank line in the Parameters table, type Rib_Thickness in the Name column.
  3. For Category, select Model Dimension.
  4. In the graphics window, select the dimension for the thickness of the rib as shown.

  5. In the Parameters dialog box, click OK.
  6. If required, in the Dimension PropertyManager, click .
    You have defined the rib thickness as a parameter. A variable named Rib_Thickness is added to the Design Study.
