Text dotazu:
Hello,

When I access the RootParameterSet object of a ProfuctDocument.Product it does not contain any parameters.

The ProductDocument.Product.Parameters. RootParameterSet.AllParameters.Count returns 0 (zero) when there are default 5 Parameters in every ProductDocument.

What am I doing wrong?

I have explored for any Option / Setting and searched the net also without any success.

Thank you for any help.

Hi,

I did a quick test and it seems this is normally working. Have a look at the attached image with a small example. The script always returns what is expected.

A tip for you. Try to use object Document.Product.ReferenceProduct.. instead of Document.Product, maybe it helps....

Appreciate your prompt response.
I am trying to access the parameters of the Top ProductDocument.
I was expecting that the default parameters like 'Part Number' could be accessed through RootParameterSet which I now understand was wrong.
When I added a user parameter to the top assembly, then count showed 1.
Since I am accessing Top Assembly Document, there is no need to use ReferenceProduct property.
Also, it now seems that the RootParameterSet can contain only User Defined parameter. (DirectParameters property). So, I am just wondering what additional parameters can AllParameters collection contain.

The RootParameterSet represents the "container" where users parameters are strored (and also located in tree).
PartNumber (and Description, Revision etc) are properties of a Product object (but also can be accesed like parameters), and the last group of parameters is UserRefProperties.

The best approach how to access the specific parameter is via Item method. I am not 100% sure at the moment but I think that the collection Part / Product.Parameters contains all in Part / Product existing parameters.

Only when you want to list parameters of specific set you can play with ParametersSet. There is also a method Sublist which returns nested (or maybe better said added) user parameters e.g. in a Sketch etc.
