240 | Chapter 11 Using Design Variables
In addition to the method used in the following exercises, you can create
design variables in the Equation Assistant dialog box while you are in the
modeling process. In the Equation Assistant dialog box, you right-click in the
variables list area and choose New. A space for the new variable is provided
at the end of the list, and your cursor is positioned in the Name column.
There you enter a name for the new variable, and then you define it in the
Equation column.
In this lesson, you create variables and parametric equations to control the
number of revolutions, height, and diameter of the sweep. You also assign a
variable to control the radius of the profile that is swept along the helical
path. Because you are working with a single part, you create these variables
as active part design variables.
To create an active part design variable
1 Use
AMVARS to create a design variable.
Desktop Menu Part ➤ Design Variables
2 In the Design Variables dialog box, make sure the Active Part tab is selected
and choose New.
3 In the New Part Variable dialog box, specify:
Name: Enter rev
Equation: Enter 8
Press
ENTER.
