Thanks for creating a way to show threads, we need the help. I'm very interested.
The subject of threads has been brought up many times over the years, most recently 6 months ago, do a Search on Threading.
This is what I posted, and this is just my opinion on the topic.
<<<< It would be ideal to have a choice of cosmetic or modelled helical threads
in the model. The most important issue for me is Model to Sheet.
Model to Sheet needs to use the model threads to place the correct threads
in the drawing.
The amount of work needed to make a drawing is very time consuming, and
yes, contrary to popular belief, customers still need a drawing. The
drawing is a legal document showing revision levels, changes, material
etc. and has the required signatures and initials of engineers, quality control,
etc.responsible for the products they are ordering or producing.
We need the models for CNC production, the models are nice to look, but we
still have mountains of paper drawings on the shop floor, hanging in folders
on machines, work benches, file cabinets in quality control, and also
on my desk.>>>>

Need an easy way to show section views with simplified threads.

I would say, the easiest is you end up with a library of 2d symbols for this. Similar to the ones provided, but make a master file, show points, and then this can be edited in length. Apply a hole, at tapping size to the model. This way anyone manufacturing to the model, has the correct information. Then on a section view, apply the symbol and you get something like the attached.

I tried other way but the view is generated by what you select in the model. If this changes, i.e you add more stuff to it, you can't seem to get that on the view, so you need to be pretty sure of what you have before you flatten it, and then apply the symbols.
