Part Family Thread Call-Out
Part Family Thread Call-Out
(OP)
Hello Everyone,
Is it possible to link thread size/callout with a part family table, i.e if the diameter increases and pitch is specified will the thread call-out change automatically? For eg. if my body diameter changes from 0.25 (pitch=20) to .312 (pitch=18), then can I change the call-out from "1/4-20" to "3/8-18" automatically. Is this possible?
Thanks in advance.

RE: Part Family Thread Call-Out
Attached is an example family table, a simply block with a threaded-hole. As you will see from the Family Table spreadsheet, in order to control the size of the threaded-hole you need to only change a SINGLE expression, the 'string' expression which calls-out the 'Thread Size', such as "1/4-20". There is NO need to mess with the other expressions for the size of the hole since they are controlled by the 'Thread Size' expression. Note that for this to work you must make sure that the thread sizes used in the table are valid sizes found in the threaded hole tables. Also note that if you wish to change from say a 'Course' to a 'Fine' thread, then you will also need to include the expression for the 'Thread Standard', but as long as you stay in the same standard, then all you need is the 'Thread Size' expression.

Great Example, This works with any number of Threaded hole on your component.
You just need to make sure, you denote Thread Size expression for different Threads correctly.
For ex. Thread_Size_Frame_End && Thread_size_Outer_End etc.

RE: Part Family Thread Call-Out
I am finding difficulties when I try the above said thing for external threads as it is not taking "Thread Callout" as a parameter. Could you please help me out with external threads with the help of an example.
Thanks in advance.

It might be possible to create a workaround. Do a hole in a solid corresponding to the dimensions for your male thread, and subtract it from the shaft. With later versions of NX that support threads with boolean operations, this should work.
Could anyone try it?
