Rule Expressions

In setting classification and Tag Rules, you are using expressions to extract 3D model elements.

It is perfectly legitimate to use the syntax:

ALL WITH (PURP EQ ‘ABC’)

However, although it produces the required result, it is time consuming since all the databases in the whole MDB are scanned if opened in read mode.

It is better to include a qualifier in the command:

ALL EQUI WITH (PURP EQ ‘ABC’)
