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.
Step 1
We create the model below as an example. We will use the cut to create a Circular Pattern around the center of the disk.
Step 2
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.
Step 3
Create a Circular Pattern, and select the cut as the feature. Select the axis or the revolved face as the pattern center.
Step 4
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.
Step 5
Accept the Pattern and rebuild the model. Notice that the EQUATIONS folder is now available in the Feature Manager Design Tree.
Step 6
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.
