[QUOTE=corrado;49273]As far as I know, when there is nothing between the two flanges but just a gasket, and the two flanges have the same boltref, then it takes the length attribute and doesn't go to the Nstdblength table.
I am talking about the OLD method.....
corrado,
I think you are right.
After searching and trying:
1. The Length attribute will be used when there is nothing between the two flanges but just a gasket, and the two flanges have the same boltref[/U].
2. The Nstdblength table will be used when:
- There is nothing between the two flanges but just a gasket, and the two flanges have the different boltref[/U].
- There's wafer item (not a gasket) between the flanges.
And in this case, as pitch said:
[QUOTE=pitch;49258]
Isodraft goes to the boltref of Flange 1 of the joint, it then takes the value of length of the Sbol and divides by two.
It repeats this for the second flange in the joint, again taking half the value of the length.
It then finds the length of any wafer items that may be present.
All the derived length values are then added together (1/2 length 1 + 1/2 length 2 + any wafer length)
The Nstdblength list is then searched to find a match for the total length. If an exact match is not found it takes the first entry greater than the calculated length.
It is eventually down to you what entries are available in the Nstdblength table
You can change the length of the Sbol as much as you wish BUT you still need an entry in the table to match.
Corrado is correct. My mistake, (must be an age thing)
I have just tested it out and if the two flanges have the same BLTREF then the NSTDBLEN is not used and the Length of the SBOL is output.
In fact it will output the Length of the SBOL if the Length is not in the NSTDBLEN table
It also works even if NSTDBLEN is unset.
As for documentation, there has been no documentation for OLD Bolting since NEW bolting was introduced with Version 11.1 in 1997 (14 years ago).
So you will need to find something from Version 10.5 or earlier.
That is one of the reasons that I say OLD should be abandoned.

Where is the new bolting method is documented?
[Old bolting method]
the oldest version that we've is 11.5. So,could you please send me the documentation of version 10.5?
I do not have it, but if I did I would not be allowed to pass it on.
You need to ask AVEVA if they have a copy.
Or you could try using the NEW method. There is lots of stuff about that both in the manuals and in posts on PDMSWORLD
[QUOTE=DRAFT;49250]Please,
(Method: old bolting Method)
When does PDMS use Length attribute to get the bolt length and when does it use the Nstdblength attribute?
I deduce that pdms uses it with wafer items. Is that true?
So back to your original Question.
It seems that the NSTDBLENGTH attribute is used when you have wafer items and also when there are different BLTREFS in the joint.
same boltref[/U].
