Family Table with varying external threads

[JustinSauber]

I have a family of parts that I need to create. Each part has an external thread that varies in size up to 3/8-20. My company has an internal document that governs the undercut length (from pitch of thread) and undercut diameter (from minor diameter). Can anyone offer up some advice as to how to setup the family table and the relations? I am thinking that I am going to have to create a custom table that will be referenced. Does that table need to be internal or external to the part? Is an external reference even possible? Any help will be appreciated.

Regards,

Justin

You can either add the dimensions for the feature to the family table or add references to a UDF that has a family table.

Justin,



The approach that you are thinking of is GOOD. Most companies take a very careful look at how their fastener files are managed. Sometimes these fastener files become a burden in the database because too much is put into them.



Personally I like the idea of being able to swap out fasteners that are patterned. A well-managed family table will allow your users to do that. IN FACT I even considered having different heads (IE socket head and hex head) in the same file.



Whatever the case for you, Pro/E has the answer.
