Nominal hole diameter for thread
Please in the excel edit for thread, then they have it the next time as they wish

I would prefer the excel as it can then be used in the company.
Of course with markings.
But that is just one way.
I don't 
The excel spread sheet is correct and shouldn't be changed.. The document setting/template should be set and would apply on a company basis and used that way "if" thats what they really need..
The only real reason (that I can think of now) for needing 7mm is because of direct use of the CAD file by CAM software.. other than that minor diameter should be used and tap drill can easily be called out if needed in the drawing without changing the spreadsheet...

The diameter 7mm is the one used from the manufacturer and this diameter is also functional for us in term of internal volume. That is the reason why I need to represent it on my model.
The solution of making a 7mm hole and then apply a thread on it also works indeed, I was just wondering if there were a "more straight forward" solution.
Thank you all for your help!

Did you read what I wrote?
Does that work for you? (It should)
I'll post it again..
Go to "Tools..application options.....document settings...... modeling tab
and see the "tapped hole diameter" section..
Change it to "tap drill" and you will get your 7mm hole..
It can't get any "more straight forward" than that..
That setting is there specifically so that those that want threaded holes (placed using the hole tool) can change the "as modeled" size to be either minor or major or tapped drill,etc...
Hi Robert,
You will need to change the Document setting in the template file also. I assume you use the system default templates. Go to C:\Users\Public\Public Documents\Autodesk\Autodesk Inventor 2019\Templates\. Open Standard.ipt and make the change there and save it.
Many thanks!

Hi, I have the need to display threaded holes as the tap diameter not minor diameter. I tried the mentioned solution and I get a message "Drawind Manager thread representations are generated correctly only when Tapped Hole Diameter is set to "Minor".", this message appears to any option other than "Minor". So it seems these options are there for no reason and don't work. I also checked the diameters and they were still minor diameter instead of the tap diameter. Inventor version: Build: 330, Release: 2019.4. Any ideas?
The message you receive is merely an alert to let you know that drawings made from this model will not show the hole correctly if it's not set to Minor. If you're OK with that, then change it to Tap Drill.
In other words, a drawing of a model with tapped holes shows the hole size specified in the model, and this is typically the minor diameter because that represents reality as nearly as possible. But if you need your holes to show the tap drill size, then that's what your drawings will show also. I don't think anyone will notice, because hole annotations come from the hole data, not from the geometric representations; and because the tap diameter is typically very close to the minor diameter.
However, if your threaded hole is a tapered pipe tap, then it does make a noticeable difference. Tap drill and minor diameter are not only different in size, but also in angle. Tap Drill representation is cylindrical, Minor Diameter shows the conical profile, as it should.

I have to disagree with this opinion and the hole notes being based on minor instead of tap drill diameters. Mainly, due to the - realistic - requirement of Thread Depth. Having the bottom part of a partially-tapped blind hole (the only realistic tapped blind hole type) set at the minor diameter is not only wrong, but just (IMHO) lazy programming, both of the feature AND the hole note.
And MAN do I still hate this forums' posting software.

It may not be realistic, but it is normal drafting practice. In addition, hole annotations, by default, do not reference the minor diameter nor the tap drill diameter; again, normal drafting practice assuming that the fabricator knows what they're doing in selecting the tap drill. If you need tap drill to be specified, then dimension styles can be modified to include that information.

Thank you for the explanation. If the message is just informative let it be. But, as I understand, if I switch to "Tap Drill" and click "Yes" on the message, I should get a change in the measured dimension of the hole. I do not see any change no matter what I pick in the drop-down. I set the Tapped hole diameter to Tap Drill, I create an M6 threaded hole, I put the model onto a drawing, the full circle gives a diameter of 5 (I expect that to be 6), the thread line around the hole (which isn't a full circle) gives a radius of 3 (which matches with the M6) and the "Hole and Thread note" tool shows the appropriate information. Now the issue is when I put this in a DXF file I get a 5mm circle but I wish it to be 6 in my case, I hoped that the tapped hole diameter setting would achieve that but it does not change anything. What is the setting supposed to do?

We've always specified tap drill sizes in our notes. Probably much less so in Metric, but some Imperial sizes have a few choices in drill size (again: thread engagement depth), that if left to some machinist's desire for speed and tap life, could result in threads a bit closer to class 1B than 2B.
It's just measuring the model or drawing after the fact and ending up with hole diameters (below the end of the thread) that gives pause as to why the odd-ball measurement result. Oh, I just remembered: the MAJOR thread diameters aren't nominal either.
I guess I'm being way too old school, wanting a 3D program to make tapped holes like on a drafting board (nominal hole diameters with nominal major thread diameters). Get off my lawn, I guess.

Now I'm confused about what you want. You say you want to see the tap drill diameter, which is 5mm for an M6 thread; but when you get this in a DXF file you want it to be 6mm? That's the major diameter, which is incorrect and useless, isn't it?
Here's what I get with an M6 blind threaded hole, first with the minor thread diameter, and second with the tap drill diameter:
I can see where using the tap drill diameter might be preferred (I was incorrectly thinking that tap drill would be slightly smaller than minor dia -- doh!), and there's no reason not to, except for tapered threads.
