In Windchill, Design Reference and Assembly Design Reference are the two types of references. The references shown in Windchill are the same as those shown in SOLIDWORKS. A Context Reference in SOLIDWORKS is designated as an Assembly Design Reference in Windchill.

The following graphic is an example of external references showing an assembly structure.

Use Case — The following graphic shows the List External Reference window for Part 46–1P_2.

Part 46-1P_2 has a context reference with Assembly 46-3A_2, as well as a reference with assembly 46-4A_2 (shown in Referenced Entity column). The References window for part 46-1P_2 displays references as shown:

The following graphic shows the List External Reference window for Assembly 46–4A_2.

The References and Referenced By windows for Assembly 46-4A_2 displays references as shown:

The Referenced By window for Assembly 46-3A_2 appears as shown:

SOLIDWORKS allows multiple context references. To assign multiple context references in SOLIDWORKS, click Tools > Options > External References and enable the Allow multiple contexts for parts when editing in assembly check box as shown below:

You can define multiple context relations in different sketches of a part.
