PartDesign threads drawings are non-standard #33

There is an ISO standard for drawing simplified threads. Here is a preview of an old version: ISO-6410-1981.pdf. There is also an ASME standard (I don’t know the number) which is very similar, the biggest difference is that the thin lines are dashed.

The following illustration gives an idea of how it should look, though it is not fully compliant to ISO 6410.

I think, this is not possible to solve in Cosmetic Thread 3D directly. It is TechDraw problem. The TechDraw can just create lines from edges. I have no way how to control look of the lines from model side into TechDraw... This will lead to fixes or better improvements on TechDraw side I think.

Let’s ask @WandererFan then.

There are tools in the Extension toolbar to draw these but these tools don't understand Hole features.
