You are going to have to elaborate. I assume you are talking about a side view or end view of a threaded shaft or hole. Are you wanting to model the thread grooves? Or do you want the simplified representation of the thread that is defined by drawing standards such as ANSI or ISO? the latter is what you typically put on production drawings.
This should be simply drawing the dashed lines to represent the thread.
You are going to have to be more specific as to what you need.
In Solid Edge you create drawing views from the threaded 3D models that produce all the lines that specify the thread diameters and thread depths.
In 2D it is up to the user to draw them.
I still need more information.
I think you may have answered my question. I had been hoping that I would be able, in 2D, to easily show a side view of a custom round 'nut' with the female thread form through the center of the nut visible. As this particular drawing I am making involves a standard thread, I will simply use a dashed line to represent the thread.
