Sometimes you need to drive a dimension or value using a Global Variable. In this case, we will control the instances of a hole in a Circular Pattern using a Global Variable.
We create the model below as an example. We will use the cut to create a Circular Pattern around the center of the disk.
Next we will create a Global Variable called “NUMBER” and give it a value of 4. Select TOOLS/EQUATIONS to access the menu.
In the Global Variables section, enter the name” NUMBER”, and the VALUE as “4”. Select OK to accept.
Create a Circular Pattern, and select the cut as the feature. Select the axis or the revolved face as the pattern center.
In the “Number of Instances” box, enter the equal sign “=” to access the Global Variables that are available. Select the variable called “NUMBER” that we created before.
Accept the Pattern and rebuild the model. Notice that the EQUATIONS folder is now available in the Feature Manager Design Tree.
Change the Global Variable and see how the model reacts. Right-click EQUATIONS and select Manage Equations.
Change from 4 to 6, and press REBUILD.
Your model should now have 6 holes.
