Once I was asked by a customer about standard thread. He ask:
"My design ho, have thread at the end of my part but ho, your library have everything except standard thread le. So, I have to sketch the thread manually again and again le, how ar? Got faster solution?"
Yes, most of us usually didn't model the thread in detail. But there are industries would need to do so. So, how? But since he using it most of the time, i suggest him to create his own library. Do you know how to create your own library? It definately save you a lot a lot a lot time. Below video guide you how to do it and I'm sure you'll say: Wah, so easy geh!~
