Creating threads
Do you really need to make the actual threads or just specify the threads in a drawing?
I ask because creating the actual representation of threads is not an easy task. It's not just a simple rotation of a coil.
If you just need to call out the threads in a drawing, Inventor thread command will do such. The model will look smooth with the exception of the bitmap that "looks" like threads, but when you detail it by using the Hole and Thread command, the specs of the thread you selected will be posted on the drawing.
If you do need to create them in the model, simplify them as much as you can.
So @Anonymous's question is this: Do you need the actual threads cut into your part?
Typically this is done because the 3d model will be printed, the thread is non-standard, or the 3d model will be used for FEA studies of the thread geometry. If so, then using the coil command and the correct drafting technique will get you the shape you need.
Exactly modeling the thread is computationally expensive and really drags down large assemblies with many threaded fasteners. The normal technique used in industry is a cosmetic thread. This is a visual representation of the thread on the part and a thread note on the 2d print. It is much less computationally intensive, so assemblies of 10s or 100s of thousands of components are possible.
Which method matches your needs?

I like to know (sorry for hi-jacking the posting).. If you are a student how are you running Inventor 2016? Students are no longer entitled to use that version and your 3 year license would've ran out by now..
Or do you mean your purchase a commercial license of Inventor 2016?
Update: I see your Autodesk Account states "Retired but consulting".. So are you really a student (in the sense going to school)?
