Every once in a while someone posts a question about how to create threads. Other than the cosmetic threads that are carried over to the drawings and called out in the drawing view, sometimes the thread form needs to be created for "show". Some time ago I came across a YouTube video that showed how to create the threads without having to decipher the standard profile illustration that is sometimes shown above screw thread data charts. I have been using that process for those times I needed to create a thread form. Since I have some free time I thought I'd use some of it to condense the info from the video into four illustrations for creating internal and external threads using both the Helical Boss and Helical Cut in Alibre. Be aware that creating threads add a lot to the model and can have a detrimental effect on you computer performance, especially if you happen to have a lot of fasteners with threads. So reserve the use of thread features to those times when it is necessary, like in a render for example. I am uploading the crib sheets here for anyone that would like them. Hope you find them useful. Edit: I uploaded this crib sheet to the Resources along with some spread sheets of thread data. Only the data used for the thread sketch profile and location are in the spread sheet..
