If you click on the isometric view in the drawing that is lacking the cosmetic threads, and then click on the "shaped with edges" icon in the top right, it will show the cosmetic threads (as well as the fully shaded model, etc).
I do not believe you can make them appear in the "hidden lines removed" view that is default (and what I assume you have currently selected)
I have to disagree with you here Dave... I have moved over to the SW crowd after having used both for quite some time. I learned Inventor first, and was fairly proficient. I went through the SW tutorials one night for my class, and was easily able to create parts and drawings in SW in what seemed like half the time as with Inventor. This was after working with Inventor for nearly 4 years, and having used SW for only a matter of hours. Granted, the programs are similar, I find myself with alot more free time now that I do everything in SW. Just my opinion though...
