Thread Dimensions

[Anonymous]

I am wanting to model a 4 1/16 -12 thread on a part I am working on, however no matter what size I model my ID hole it will not give me an option past 4.0 diameter.  I know I am being picky as it is not needed for me to do the actual part.  I just am wondering if there is a way to override the default max of 4.0.  I do a few custom threads that are non standard and wondering if I can model them.

Hi,

You can scale the thread after applying it

If you can share a picture of what you're after, I'll show you how to do it

Its a 4 & 1/16th -12 thread.  I have the minor set to my drawing dimension of 3.977.

One thing you can do is create a custom thread .xml file.

It was posted before:

There is a way to accomplish your purpose:

1. go to thread data folder--> [Fusion install path]\Fusion\Server\Fusion\Configuration\ThreadData

2. make a copy of the thread family that you want to customize, for instance: "ACMEScrewThreads.xml" copy to "MyThread.xml"

3. open the "MyThread.xml", change the "<Name>ACME Screw Threads</Name>" to "<Name>My Customize Threads</Name>"(any name is ok, just make sure it is unique)

4. define thread shape for your customize thread: add "<ThreadForm>0</ThreadForm>" under the <ThreadType>, 

        0----trapezoid; 1----sharp; 5----square; 7-----withworth

     if you don't add this, default shape is trapezoid

5. now you can customize anything, including the pitch/diameters...

Please note:

•  If you create a thread by your customize file, and save the f3d document, and open it on other machine, when other people try edit the thread, he will get an error message "...the current thread family has no suitble type..."
• If you directly change a standard thread type, and create a thread save to f3d document, when other people open it on their machine, recompue or edit the thread will get back to standard shape.

Not the greatest coder, where do I add that in? anywhere or at the top, or bottom?

Copy this file into your ThreadData folder and it should show up in your list after restarting Fusion.

Here it is showing internal threads.

Double check my numbers as I did this really quickly and could have missed something....

Awesome, thank you.  This will allow me to model my weird custom threads I get.  Thank you much. I appreciate it

Make sure you keep a copy of that file and any changes you make to it in a safe place other then the ThreadData folder for 2 reasons...

1) In case anyone else wants to open your file they will need it...

2) Because if I remember correctly you will need to copy it back into the ThreadData folder if you reinstall Fusion or if it is updated.
