Creating Design Variables

You now create design variables to represent the design points in your model, except for POINT_4, the handle end point. You do not modify POINT_4, because doing so would not meet envelope requirements for the mechanism. In subsequent chapters you will use design variables to run design studies and optimization.

To create design variables:

1.	Right-click the design point POINT_1 (0, 0, 0), point to Point: POINT_1, and then select Modify.

The Table Editor appears.

2.	To set the display of the Table Editor, click any cell other than the top left cell.

3.	Now, double-click the Loc_X cell for POINT_1.

4.	Right-click the input box at the top of the Table Editor, point to Parameterize, point to Create Design Variable, and then select Real.

This creates a design variable named .Latch.DV_1 with the value of 0.

5.	Select the Loc_Y cell for POINT_1.

6.	Repeat Step 4.

7.	Repeat the above procedure for the x and y locations of POINT_2, POINT_3, POINT_8, and POINT_9. Your Table Editor dialog box should look like the one shown here:

Note:

Make sure your design variable names map to the design point locations, as shown above. This becomes important later on as you perform your design study and optimization.

 

8.	Select Apply.

Design variables now control the locations of your design points, with the exception of the POINT_4 location.
