I have been looking at the options in Solid works for creating a threaded cap that I need to print on our 3d Dimension printer.

I only found under Annotation - Cosmetic Threads , however when I save the file as a STL file format and send it to the printer the threads do not show up !!!!
I have looked at a few disscusion groups but I still haven't found the answer .

I was wondering if any one else out there has any luck creating an internal threaded hole or an external thread ?

I am still a noob using Solidworks , so any help would be great !!!

Thanks
