Multi-Value parameters paired with a simple select case in an iLogic rule can be a very powerful tool for simple configurations inside parts. Below are steps to switch from different shapes of holes at a click of a button. This can be expanded upon to create more complex and adaptive parts.
Step 1
The first step is to make a multi-value parameter. Simply make a user parameter (in this case a text parameter), right click and select “Make Multi-Value”. This will launch a dialog where you can add all the values you want selectable in your multi-value parameter then click the add button to add them.
Step 2
With your Multi-Value parameters set up you can now change which value is selected. Now to use this parameter, make some features in your part and then suppress them. Below we’ll write some very simple code to unsuppress one of them based on your multi-value selection.
Step 3
This code is what is called a select case. It checks one parameter’s value and runs some code based on that value. Here we are just looking at the value of HoleType and then setting features as active or inactive. You’ll want to name your features that will be suppressed or unsuppressed so that you can refer to them easily here.
Select Case HoleType Case "Circle" Feature.IsActive("CircleHoles") = True Feature.IsActive("SquareHoles") = False Feature.IsActive("TriangleHoles") = False Case "Square" Feature.IsActive("CircleHoles") = False Feature.IsActive("SquareHoles") = True Feature.IsActive("TriangleHoles") = False Case "Triangle" Feature.IsActive("SquareHoles") = False Feature.IsActive("CircleHoles") = False Feature.IsActive("TriangleHoles") = True End Select
In Conclusion
With that done, you can switch between your multi-value parameter’s values and see your model switch between your designs.
