This is somewhat related so I'll sneek it in. Its been bothering me for a while. I've mentioned to SolidWorks, my reseller, posted threads on it, with no real response. I'm hoping my perserverance will pay off. There is a difference in how PDM/Works displays base parts versus how SolidWorks Explorer displays base parts. SolidWorks explorer places the base parts under the parts where they are being used, like you expect. PDM/Works places the base part all by itself. Furthermore if you do reporting on an assembly that uses a part, its base part doesn't show up in the report. This is annoying when trying to understand the correct assembly/manufacturing process. SolidWorks Explorer has got it right, PDM/Works (where we really need it) has it wrong. Try some tests with base parts and parts from that (for example a casting and then its machined part). You'll see that the two display things differently.
