Summary
Form controls limit the shape of individual features without reference to datums.
Scope
Use form controls when you need to control shape only, independent of orientation or location.
Controls in this category
When to use it
Use form controls to ensure a feature is straight, flat, round, or cylindrical within a defined tolerance zone.
Common mistakes
- Referencing datums for form-only requirements.
- Using a location or orientation control when only form is needed.
