Precise vs. Imprecise by default 2

[SMO]

Hi,

The last company I worked at ran Imprecise BoM's by default and the current company I'm at defaults to Precise?

What does that means exactly?

I understand the meaning of Precise/Imprecise but what are the settings that dictate the, lets say Precise "default" standard?

I looked through the Customer Defaults and found a couple of things but that only seems to be part of the puzzle, if any.

From what I can tell, all the Save commands here save Precise BoM's (not limited to the "Save Precise Assembly" command).

Then I can see that the default Revision Rule is "Precise Only."

Is that all that makes a company Precise BoM by default or is it more than that?

That is a Teamcenter setting and not NX.
It is a site setting and nothing a user can change.

Simply described,
When Precise, You store/keep track of what revision an Item should have in a product. I.e Item + Item revision is tracked.
When Imprecise, you use revision rules to control the revisions of the items in a product. Only the Item is tracked, not the revision.

In managed mode (teamcenter integration) of NX you can select (assembly load options) which revision rule to use. The rules are determined in Teamcenter.
You can also select the Configuration context. Either load (use) them from Teamcenter or Define them in NX.

The last one lets you select how the structure is loaded regardless from how it was saved in Teamcenter.

Thank guys,

Do either of you know where this Site setting is in TC or is this simply the administration adding Precise entry at the beginning of most Revision Rules?

If I'm correct the rules are determined in the BMIDE for Teamcenter.
That is the configuration tool for your Teamcenter Environment.(Configures your Datamodel, Item types, Naming rules, Attributes etc...)
Not accessible for normal users.

In Teamcenter, Edit, Options, Product Structure.

This won't allow users to change things at will though. Tread light, and consult you TC admin.

In Teamcenter, Edit, Options, Product Structure.

That is only for the creation of NEW structures. Doesn't have an influence on the loading of existing ones...

Someone correct me if I'm wrong (I'm no TC expert), but in addition to the advice above, I think you need to use "save precise assembly" from the save menu if you want to later recall the assembly in the same (precise) state.

Cowski,
If the TC system is set to Precise as the default ,
you do not need the "save as precise", all assemblies will be saved precise anyway.
( I do not know what it does...)

That makes sense. Thanks, Toost.

Thanks cowski,

That's what I gathered in my research (all save are precise) but its hard explain this concept to others without knowing why this is the case and where the Precise default setting comes from.

All the responses above have been very helpful.

We work using imprecise. Occasionally we will have an assembly that we want to save as precise, to "archive it". In those cases, "save as precise" is used, but you have to be careful. We had a user make a concept assy 'precise', so he could compare various revs of parts. Once it moved from a concept, to reality, changing it back to imprecise did not happen, and it propagated to sub assemblies. Luckily we caught it in time, but mixing precise and imprecise should be done with care.

If you run Precise, you can toggle that in the Structure Editor.
and you can compare the result of different revision rules side by side in the Structure Editor + Graphics compare. ( also in precise mode.)

The possibilities to f.. things up have never been greater
