Thanks so much for all the input!
At this point I'm pushing to do some testing on actual parts to see how orthotropic the material really is. I'm hoping that the way the test coupons were shot in the mold, all the fibers are oriented along its length much more so than a real world part would...
I have a customer who is using a plastic with a sort of carbon fiber fill material in various injection molded parts. The material is well characterized and quite orthotropic (anisotropic). They want to run FEA on these parts, but I don't have experience running FE simulations on orthotropic...
Thanks for the advice guys.
To answer your questions:
JMirisola: Undersized parts is a concern as a result of undersized models and doing a blanket +/- .XX" tolerance. In the past I have noticed parts of a given weldment being undersized, but the over all dimensions always came out OK...
I did a search and didn't come up with much, so if I'm asking a FAQ, please point me in the right direction.
What is the best practice for sizing parts in an assembly?
Say you have 2 parts, one goes inside of another. Specifically in my case 2 sheet metal parts that get welded together...
That sounds good to me.
I suggest adding the link CorBlimeyLimey posted to the efunda.com UN standard chart.

Also, where will that FAQ go? Is this the correct place? There are so many categories and sub...
You guys are awesome!
Thanks for the help here, I knew I had to be making this more complicated than I needed to be.
Your assumption that I wanted to use Unified standard is correct.
.75" is referring to the thread depth, i don't know why i threw that in the OP. Sorry for the confusion...
"I suspect I can find the answer in the machinery handbook, however, I am off site and cannot get to one easily. (Is there an online version?)"
As I stated, I'm off site and can't get to one easily/quickly. I'm kinda hoping this is a fairly simple answer that someone here can supply...
OK, I'll start this off with an apology, as I know this is a basic issue. I will also state that I have searched, both here and google with no real success. I suspect I can find the answer in the machinery handbook, however, I am off site and cannot get to one easily. (Is there an online...
