Expressions

Expressions are used to gather named entities needed for various operations.

The special characters used are “*”, “!”, and spaces or commas. These characters can be used within a string as follows:

• “abc*” collects all required entities with a name starting with abc.

• “*abc” collects all required entities with a name ending with abc.

• “*abc*” collects all required entities with a name containing abc.

• “!abc*” collects all required entities with a name that is not starting with ab.

• “*abc,*xyz” “*abc *xyz” (comma/space represents OR) collects all required entities with a name ending with abc or xyz.

The following example uses expressions in the ScopeDefinition class. The part_expression parameter is used to gather part entities to define a scope. You can provide the exact part name or use expressions for more complex entity collections.

>>> part = model.parts[0]
>>> # First part in model
>>> scope = prime.ScopeDefinition(model=model, part_expression=part.name)

>>> # All parts except solid
>>> scope = prime.ScopeDefinition(model=model, part_expression="* !solid")
