Is anyone using or know of anyone else using Schematic Thread display on drawings, which is an option in ASME Y14.6 (image below Fig 2)?

I have used it in the past, but only on board dwgs.

The Simplified methods are trivial for 3D CAD as they can be generated from the hidden line removal algorithms on stand-in surfaces representing the thread minor and major diameters.

Some users are going full on with depicting actual cut threads on parts.

I recall the drawing style that was required for US patent drawings - I think those are no longer required; cannot imagine that the schematic threads are much used either.

I don't see a demand for the schematic depiction . I think I learned about them 50 years ago in a drafting class and never used them again in any mechanical design. Sure, they jump out and say "here's a screw thread" but so does a fully threaded shaded 3D model, which is it's own can of worms.
 
fcsuper,

I have manually done the simplified representation, particularly on section views, using SolidWorks. This will survive drawing updates. If the schematic representation were available, I would probably use it on occasion.

I would say leave it in the standard. Maybe some CAD programmer will implement it someday.

The Simplified representation conveys all the info needed. 40+ years ago, I used the Schematic rep in school but once in industry, only the Simplified was used and that even from the days of hand drafting. The Schematic rep is labor-intensive and provides very little benefit. I wouldn't use a Schematic rep even if the CAD system had that option. I use minimal hidden lines on the drawings I do and using a Schematic rep for threads would just create a cacophony of lines. The shops and engineers I work with have no issue with the Simplified rep, even when working with detailed mold design drawings. Everyone 'sees' the threads in layouts/drawings with the Simplifed rep without issue. But some may like the Schematic rep: to each his own . . .!
 
Sorry, didn't mean it.

My thread on the issue already existed, I just was excited to see someone caring about both, SW and GD&T and actually trying to do something.
