creo 3.0 threaded holes

[michisub]

Good morning.
I couldn't find an answer in the finder.
I am new to creo 3.0, I can't make threaded holes.
using the command "hole", select the icon of the screw, I choose iso, the size m8x1.25, posiziono on the face and axis, but when the position appears ø0.007, evidentmetne too small for a hole m8, and does not make me continue, or gives me error messages like "change the accuracy of the part making it less than 0.000...."
if instead select the simple hole, not threaded, it works, but then obviously I do not have the thread.

I have seen all the amount of variables and features set by the user, including the accuracy of the part, but I do not know sincerely what I have to change.

It's all morning I've been spraying tutorials, forums, ptc guides, English creo manuals, but I don't come out... Help.
Thank you.

the hole function threaded by this result when there are inconsistencies, of the type to drill a sheet with sheet thickness lower than the pitch or things like that.
controls the thread depth compared to the hole depth, by default it is set for a multiple depth compared to the hole diameter.
precision doesn't need to change it.
in case you put a photo with open hole depth option and thread if it still does not work.

Tronchetto is often 20, so there should be no problem.
as you see from the image, the diameter of the hole is 0.007, although I have selected m8...
Thank you.

I have come to the conclusion that there is a conflict between unity of measure that I cannot find. I have set the configuration file with all metric units, but in the meantime in the thread properties it indicates "filetto per inch" and it's what stinks me...
I don't know where else to go and see to change the measuring system.

Okay, I got it.
for posters: was a problem of unit measurement: I had thumbs left in "prepara file" and mm" in the configuration file. after uniforming all the threaded hole came well.

now I have to understand how to fix these standards.. .

the inconsistency solves it by making you start-parts, i.e. parts and assemblings without solid mathematics, but with all set parameters, when you start a new file, instead of starting from scratch, start from one of these.
