thread information in the IDW drawing

[SofiaGrave4819]

Hej to all

When I am in the drawing and inserting the hole and thread dimensions, I have all the time the pitch for the thread.

ex:

M12x2

How can i remove the thread pitch from the dimension?

Dear Sofia,

Please, try the following.

• Make a backup copy of the original Thread.xls file located in the Design Data folder of Inventor.
• In Excel, open Thread.xls and activate, for instance, the sheet “ISO Metric Profile."
• Remove the pitch information from all the values in the column “Custom Thread Designation."

 

• Save the file.

Now the hole notes will not show the pitch information.

Make sure that you are using <THDCD> in the hole notes.

I hope this answers to your question.

Kind regards,

Alessandro

Hello, 

I am sorry to resurrect this old thread but the steps described by Alessandro don't have any effect on the thread representation for me.

 I don't want Inventor to show the pitch for standard threads. 

As you can see on the screenshot: the thread.xls is modified and is set for the thread but the pitch is still visible. 

(Just a side note: I am using Inv 2015 (german and english languages are installed [both thread.xls are edited], furthermore Inv 2016 is also installed but not used up to now (this problem is also present in Inv 2016, the corresponding thread.xls is also edited)

Is it possible that you edited the wrong thread.xls file?  The one used by Inventor is in the Design Data folder specified in Application Options, or overridden by the active project file (.ipj).

Hello Sam and thanks for replying,

yes I edited the right one. Both application options and the project file point to the default location (%PUBLICDOCUMENTS%\Autodesk\Inventor 2015\Design Data\). And there I edited both thread.xls files (in XLS\de-DE and in XLS\en-US).

Any other ideas?

Well I am going to answer myself 😉

It seems that these changes to the thread.xls files don't affect parts (not drawings) created before the changes.

If I create a new part and a new drawing of this part, the thread note is as it should be.

Creating a (completly new, but same template and thread.xls as in example above) drawing from an older part leads to the wrong thread notes.

Is this behavior intended? Am I the only one with this behavior? 

Does any one know a way so that the new thread notes apply to older parts also?

The behavior is intended..

Don't think you can do anything about older ones.. 

"maybe" if you edit the hole again and just pick the same thread then "maybe" it will pull in the modified thread information from the xls file..

Of course, personally I'd ALWAYS include the pitch.. Not having the pitch just opens you up to errors..

Whats "standard" to you might not be "standard" to someone else..

Ah.  Now I understand what the problem is.

I can't speak for Autodesk as to why it is this way, but I can guess-- there is no live link between parts and the thread data spreadsheet because of all the ways that could go wrong.  If you send your part and drawing to someone else, and they have a different thread data spreadsheet, what happens?  Your drawing suddenly changes to something you didn't intend.

As to how you could update existing files, I'm sure it could be done by programming, but I don't have the expertise to even start down that path.  Anyone else?

Thanks mcgyvr,

I was playing around and discovered this by self ansd saw your posting 5 sec. later 🙂

You are right: editing the thread pulls the new thread notes.

In principle you are right about the pitch and I don't know how this is handeled outside Germany but here this sort of things are all standardised specifications, so it applies to everyone (at least in Germany). And it's common to leave the pitch for standard threads (just double checked the specification). As I said our manufacturers were calling and asking why I am noting the pitch for standard threads in my new drawings ...
