Using an Internal Component ID in Assembly Relations
When creating a relation in Assembly mode, you may need to know a Component internal ID. Every component in an assembly has a unique Component ID, even if two components have the same component name and therefore the same Session ID.
Use the following syntax when referencing a Component ID:
d#:cid_(component ID #)
To determine the Component internal ID:
1. Click Info > Component. The Component Constraints dialog box opens.
2. Select a component.
3. Click Apply on the Component Constraints dialog box. The Information window displays the component information including the Component ID.
The Model Tree in Assembly mode displays the Feature ID (the same as the Component ID) of each assembly component.
