yet another nx question that I don't seem to find in the internet is how to turn on cosmetic threads in assembly environment in the way that they are displayed as "wrapped image". Good example is SolidWorks where you have checkbox some sort of shading from software options. Is there similar option in NX and where could it be located?
There is no 'automatic' support for something like this. You have to apply a 'texture' representing so-called 'wrapped threads' for rendering purposes. In the past, I always just created the actual modeled threads since they will always look more realistic and if they is the final goal, having a TRUE photo-realistic images, then there is nothing that replaces the actual geometry that you're attempting to render.
One thing I have seen is that when people model a bolt, they split the cylindrical surface at the end of the full thread, and color the threaded part a different color.
Other options are a slightly reduced diameter for the threaded section or put a "notch" where the thread ends.
