I'd like to add a thread callout for a Helicoil tapped hole. For anyone thats used them you know they are different than a standard tap. I thought I could add a sub type in the threaded hole selection, but the excel file limits oyu to only the 1,2, or 3 option for thread types. How can we add a 4th type to this? After a bit of googleing it appears SW has a "STI" thread option. (STI = screw thread insert) Can we get one?
I also thought maybe I could just copy the 1/2-13 (size I'm using) size and adjust the drill size, add a STI suffix to the name and use that, but when you go to use it there's an error stating there's two duplicate sizes.
So is work around to make my nominal hole size larger, say .5001, and go from there?
Solved! Go to Solution.
just implement a new standard, let's say "Craigs Standard" using another excel sheet (copy an appropriate existing one)
Modify the entries according to Your needs and You can use it similar like DIN or ISO or ANSI
I was able to add the STI version to the standard "ANSI inch" but changed the nominal to .5001 to fix what I thought was this error, but it still pops up. I copied the excel sheet to a "Craigs ansi inch" it does the same.
What exactly is the "thread family identifier"? and what diameters ar duplicates? the tinted row is my STI tap.
Thought i would play with this a bit so I could be sure I understand it.
I was able to copy and paste a line with all the same values as long as I changed the ThreadFamily from UNC to UNC_STI.
So I believe that within UNC or UNC_STI family there can be no duplicate values.
