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.\*abccollects 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 abc.\*abc,\*xyz\*abc \*xyzcollects all required entities with a name ending with abc or xyz. A comma or a space representsOR.
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")
