I'm not telling you anything new when I say that the graphical representation of a thread (or a tap) of any kind is not possible on SolidWorks; This does not add anything to the design.
On the other hand, when your design goes through a rapid prototyping stage (stereolitography, powder sintering, etc.), you realize that something is missing. It is not usual to provide a plan of the part that will mention the threading/tapping, and even if the plan is provided, either the prototypist has missed it, or he will cost you a rework operation for its realization.
Hence my question:
Does anyone have a solution to generate, from the thread representation data present in the 3D model, its graphical representation?
Thank you for the answers already given, but I realize that I should have been more specific.
My need is to generate the graphic representation just before exporting, I don't want to keep it in my native solidworks. Is it possible, when inserting a library, to make it possible to select a filtering representation of an existing drilling feature in the design tree so that the drilling diameter, pitch, nominal diameter, and thread length are automatically defined?
I just have a doubt about the feasibility of your thread.
It all depends on the size, of course, but on sintering and despite the tolerance and the rather good precision, I really don't think that a thread is possible, at least from a mechanical point of view.
You might as well prepare the hole and tap yourself.
It's a small apartment, but I think it's important.
I've already proposed this library link several times but I like to advertise^^ This library contains many library functions that allow you to make threads and threads that correspond to the standards in force, this can allow you to generate your threads very easily with a simple drag and drop in your graphic area. You just need to know what type of thread the prototypist wanted to make. The library is very easy to use and very well organized, despite the not very ergonomic site. This could save you a lot of time and money. The installation of the library is quick and very well explained in the Online Help. Additionally, if you want, you can also break down the functions to see how they were performed and match them to your needs if not.
To follow up on what GT22 wrote "the one and only way to do it is to create a thread or thread actually in the 3D file"
From experience, this works very well on the prototypes launched in my company. we have even recently launched prototypes with M5 threads.
When we have smaller threads we prefer to remachine the part by ourselves (creation of a smooth hole in prototyping then passing a manual tool -> about 10min of work the time to get the tool)
