Error Specifying a Feature in a Relation

[Mostafa_Arafat]

I'm trying to assign a value for a new parameter called "AAA" using feature Name not feature ID.

This code works well

AAA = b:8

But this code doesn't work with me

AAA = b:fid_EXTRUDE

errorInvalid symbol 'b:FID_EXTRUDE' found.

knowing that:

1- the feature which is called "EXTRUDE" has ID=8

2- I'm working inside the part relations
3- I'm using Creo Parametric 8.0.8.0

I suspect that the issue is the feature name "EXTRUDE" is not unique. Try naming this feature with a unique name and follow the syntax shown here to use it in a relation.

If you write a relation in the feature’s parent model (part or assembly) or in another feature, you must use one of the following formats to reference that feature:

XYZ = parameter_name:fid_N

or

XYZ = parameter_name:fid_feature_name

How is a parameter related to a feature? As far as I know a parameter name is global in the context of a part or assembly. You can't have two parameters with the same name in one model.

Is this a method I don't know of for obtaining values from components in an assembly, where you use the name of the component instead of a session ID? Or could this be some multibody stuff?

When I've used this type of thing, it's been to extract a value from a measurement feature, like "AREA:FID_MxAREA".

If I understand what you are asking it relates to model parameters versus feature parameters. See this example of the same parameter name used in a part model. "PAR_TEST1" is defined as a feature parameter for two different extrude features in a model. They are two unique and independent parameters available for use in the model as they are defined in the context of features and not the part. You can see there are two parameters with the same name in the part and they are independent.

This is possible if you create feature parameters using the same parameter name. In this example below A is not equal to B even though the same parameter name is used twice in the model.

There are multiple structures in which parameters can be defined in a part model.

Thank you guys for trying to help.

But something wrong with all types of equations in my relations.

Please see attached photos to try to configure the source of the issue with me.

Thank you again for your efforts.

I think the issue is that in your relations, you are trying to use part Dimensions like you would use feature parameters.

In your last example, PAR_TEST2 is a dimension that is from feature FEATURE_TEST

To assign this dimension a value through relations, you don't tell the system from which feature it comes.

For your example, you simply write:

PAR_TEST2 = 1.234

or if you have a part parameter AAA, then you could assign its value to a dimension:

AAA = 1.234
PAR_TEST2 = AAA

(the value of a parameter that belongs to a feature has be recalled using the special :FID_xxx syntax as described in this thread)
