Public controls
Lists and choice inputs
List/choice-style parameters restrict or guide a value to known options. They are useful for nominal sizes, standards, component variants and imported parameters that expose an allowed option list.
- Where to find it
- Parameter/Inspector input where the source definition provides allowed options
- When to use it
- Replacing error-prone free typing with a controlled set of valid choices

Step by step
- Define or import the allowed option set for the parameter.
- Expose the choice as a main/public control when users are expected to select it.
- Use Choose Size or downstream graph logic when one selection should drive several dimensions.
- Test every important option before publishing the component.
Validation
Imported/external parameter models can validate that the current value is present in the allowed option list.
Choice → geometry
A choice itself is often only a key. Pair it with Choose Size/table lookup or conditional logic when the selection must drive many numeric dimensions.
Snapshots
Choice values can be part of saved configurations so a tester can move between known design variants without remembering every dependent value.
Keep in mind
- Prefer stable machine-readable choice values while keeping the visible labels understandable to users.
