Assembly Statistics- Unique Parts?

[MadMango]

I have an assembly, using Assembly Statistics option (SW03sp3.1), it reveals:

696 Total number of components
638 Parts
263 Unique Parts
58 Sub-assemblies
51 Unique sub-assemblies

My question is what is the difference between "Parts" and "Unique Parts"? I cannot find reference to what "unique" implies.

I have redesigned a product, and need to compare the part count of the new product versus the old to use in quick & dirty cost reduction calcs. I only need the actualy parts we will be manufacturing in-house, and not hardware numbers. I'd hate to have to cycle through every file and create configs to supress hardware (but I think this is the answer). Still, I'd like to know what makes a file "unique".

I believe "unique parts" refers to the number of actual part files used. For instance, two plates held together with four instances of the same rivet would hae 6 parts but 3 unique parts.

Thanks [blue]The Tick[/blue]. Does anyone else want to weigh-in on this issue? Perhaps one of you guys that works for a VAR... maybe with the initials SB?

You've 696 components what is inclusief parts and (sub-)assemblies. Without assemblies (totaly 58) you've 638 parts (check: 638+58 = 696). From that 696 components are 263 parts unique what means that they are different from each other. The rest (375) are 'parts' you've used more than once in your assembly. Bolts etc. are used more often in one assembly but are once unique.

Hope it make sens.

MadMango,
To prove it to yourself without question, do what TheTick says in a test. Create an assembly with two plates held together with four instances of the same screw. Using Assembly Statistics option (SW03sp3.1), it should reveal you have 6 parts but 3 unique parts.

To all, thanks. Its not that I didn't trust The Tick... I just wanted more concenus on the subject. When I see "I believe" start off a reply, I take it as a guess instead of fact-based. No hard feelings Tick?


I just wasn't able to find anything in the online help, and I never paid much attention to anything else on that pop-up window besides number of mates.

No offense taken, MadMango. I phrased my reply that way because I hadn't actually confirmed my theory. I only view it as well-placed professional skepticism.

I did a quick experiment, and it appears I was correct. Additionally, I found the following:
•part count includes parts at all levels
•two instances of a part with different configurations counts as the same part
•envelopes count as components

>>•two instances of a part with different configurations counts as the same part


hmmm... Now I gotta check... Im hoping its possible that this correlates to the "Part Number displayed when used in Bill of Masterials" selection in the Configuration properties of the Part file.... :/

>>•two instances of a part with different configurations counts as the same part

I meant that in terms of the count for "unique parts".
