before moving on to the next Project in A's list 8 . The search for a particular Entity ends when M2 is either found or
there are no more Projects to be searched.
Assuming that MODEL M2 has been found, it is entirely possible that it, in turn, refers to lower-level Entities such as
other MODELs, or variable or stream types. The search for these Entities will follow exactly the same rules as that
for M2 itself. It is worth noting that the search will always commence from the current Project A and not from the
Project in which M2 was found. This is designed to allow, for example, a user's Project to make use of a standard
library MODEL (e.g. “Reactor”) while overriding the library definition of a variable type (e.g. “Temperature”) or indeed
of a sub-model (e.g. “KineticMechanism”) by providing its own Entity of the same name.
2.3.2.3 Temporary suspension of Project cross-referencing
At any point during a ModelBuilder session, the user may instruct ModelBuilder not to search other Projects for any
missing Entities until further notice. This can be done by checking the “Disable cross-references” check-box in the
cross-references tab of the Project's Properties dialog (see Figure 2.6).
2.3.2.4 Creating a self-contained Project
It is sometimes desirable to create a completely self-contained Project that contains physical copies of all necessary
Entities, including any that may reside in cross-referenced Projects.
The creation of a self-contained Project may be performed automatically using the “Copy X-referenced Entities into
Project” utility under the ModelBuilder's Tools menu. This operation cannot be reversed automatically.

gPROMS ModelBuilder will automatically detect and deal with any circular references. In particular, no Project is
searched more than once while searching for a particular Entity
