thread561-356777: Expressions NX9: "IF" statements
I am attempting to create several KBE (Knowledge based engineering) models for several products. Utilizing expressions to create features/suppress features I have been able to accomplish many variants of the parts I would like to create, however I just saw a Catia model that used formula based decisions to utilize one sketch or another based on logic of the expressions.
I am looking to find out if anyone is using "Expressions" or "Attributes" to make decisions on selecting one sketch over another. Additionally I would like to use the same technique to select one feature over another. An example of what I am trying to accomplish would be using one surface to trim a part or utilize a different surface in the same part to trim it in a different way for another, all driving off of formulas in my expressions or attributes.
Thank you for your help.
