Associative links are automatically created in a model when referencing other components within an assembly to define geometry, dimensions, or constraints. Once established, these links enable adaptivity by default.
A prime example of adaptivity is the multibody design approach introduced in the Essentials course. In this method, new parts are generated by referencing a shared body and incorporating additional geometry into an existing part. These parts remain adaptive, ensuring they automatically update whenever the referenced geometry changes.
Controlling Adaptivity in a Model
To prevent a part from being adaptive, simply locate the adaptive reference in the Browser and disable the Adaptive selection. This ensures that modifications can be made without automatically updating the original component.
While adaptive parts can be useful, they are generally not recommended within the main assembly due to potential complications. However, they are beneficial in specific scenarios, such as:
- Early design stages when certain aspects are still evolving.
- Situations where the position of a subassembly remains undefined.
- Cases where a feature’s size depends on another part.
Breaking Associative Links
Associative links can be broken within the sketch feature and reference geometry. Once a link is broken:
- The reference no longer appears in the Model Browser.
- Editing the feature will be required.
- Missing dimensions and constraints must be redefined.
Important: Breaking associative links does not fully disable adaptivity. Even after removing the links, the model remains adaptive. To completely disable adaptivity, right-click on the component and manually disable it.
Adaptive Parts in an Assembly
Recommended Use of Adaptive Parts
Adaptive parts are particularly useful in the following scenarios:
- Early design stages – When aspects of the design are still evolving, adaptive parts allow for seamless updates.
- Undefined part or subassembly position – Adaptivity helps accommodate positional adjustments as the design progresses.
- Feature size dependency – When a feature’s size is determined by another part, adaptivity ensures automatic adjustments to maintain design intent.
Disabling Adaptivity
Breaking associative links does not automatically disable adaptivity. To fully disable it:
- Right-click on the component’s name in the Model Browser.
- Uncheck Adaptive to remove the selection.
