and the threads will cause the view update (in drafting) to take from 30 sec to over 45 min. If i put the threads in with NX it doesn't effect it hardly at all.

RE: WARNING-,I was using carr lane components
Threads are the obvious culprits but I've seen similar issues on some electrical components etc.
(Worst is an internal part though - someone modeled the mesh on on a vent shield for an electrical enclosure with HV present.)
What is Engineering anyway: FAQ1088-1484: In layman terms, what is "engineering"?

If you have tried to do a CAD model of a complex assembly by inserting CAD models that you download from third parties or component vendors, you will certainly have seen your expensive CAD system brought to its knees.
It's an artifact of people who don't know why CAD models are needed, contracting for the generation of CAD models. My first experience with it was on a Computervision system, where the Drafting Manager (Megalomaniac) asked me to generate models of standard screws. I did some grossly simplified things that looked OK if you didn't look too close. Said Megalomaniac found them unsatisfactory, so he engaged an Expert to do them anew. The Expert modeled the screws down to the slanted polygons within the Phillips recess. Of course, inserting even one of those models gave you time to get coffee between keystrokes, but the Megalomaniac was happy.

Wait until you try out a printed circuit board model generated from the PCB data. 10,000 model objects, here we come!

Then the model was sent to the FEA mesh generator and the "mesh me" button clicked.
Vendor can't figure out why the FEA has a billion elements.

The level of detail needed will of course be your choice depending on how critical it is to have an 'exact' model, but even if the only downloadable models available are 'overkill' in terms of unneeded detail, with most modern CAD systems (at least that's the case with the tools that I'm familiar with) these models can be easily simplified so that they still serve the desired purpose yet are not causing an undo burden on the system. I'd rather spend my "10 or 20 minutes" simplifying or 'defeaturing' something which I KNOW was the correct size and shape to start with then to spend that time (and perhaps a lot more) trying to hack together some crude approximation from pictures in a catalog. And once I've got BOTH the original, overly-detailed vendor model and my simplified version, if the need ever arose, I could at least temporarily swap-out my 'simplified' model with the fully detailed one to solve some unanticipated future packaging issue, again something that most all CAD systems should have no problems doing. And another thing, many people today are also using their CAD models for creating high-quality renderings of their final products. Again, it may be necessary to have fully-detailed examples of BOTH your own manufactured parts as well as the purchased Components, which could be readily swapped in and out of your production Assemblies so that these renderings can be as accurate and realistic as possible.
Anyway, that's my 2 cents worth (from someone who's been using these tools for over 35 years).

It's a matter of costs and incentives. If the boss doesn't know what it costs and put the correct incentives in place, then you know who gets the blame.

Frankly, if your CAD people are too lazy to spend 10 or 20 minutes building a suitable model using the company's native CAD system, then you deserve all the grief you got by downloading a "free" CAD model. Hasn't your boss ever made it clear that you are being paid to do your job right, rather than doing your job with the minimum amount of effort?
