expressions of type 'list'
expressions of type 'list'
(OP)
The expression editor allows to create expressions of type 'list'. The documentation mentions that list-expressions are used to "...streamline NX DesignLogic interactions and provide additional functionality capable of handling a wider variety of design tasks."
Intriguing! Can anybody comment on how to actually use list expressions? Can't figure it out and it sounds so useful...

File -> Properties -> Attributes
...and look for the attribute named 'Handwheel_Size'. You will be able to change this attribute to any of the standard catalog sizes that are available as well as an option to have an add-on 'Handle' or not (just select 'True' or 'False' for the attribute named 'Handle'). I pass the value of 'Handwheel_Size' to the expression system where it's used to determine which set of values to read from the various 'lists' using the 'nth' function and then applying those values to the feature parameters of the model.
Anyway, take a look as this should help you see at least one example of how to use the 'List' Expression.

In this case I used a NESTED 'list' expression as sort of 'truth table' to control which features are suppressed and which ones are not.

RE: expressions of type 'list'
How did you create an attribute with a pull down choice ?
Thanks in advance

...scroll down to my May 5th posting at 10:53 and you'll find a description of how to set-up these sorts of Attributes. Just remember that these 'multiple choice' attributes can be either 'strings', 'floating point numbers', 'integers' etc.
Anyway, there should be enough information there for you to get started.
