Add support for tapered threads #18

Open pierreporte opened 7 months ago

pierreporte commented 7 months ago

Conical or tapered threads are used in hydraulics, often with a BSP profile, also called Gas profile.

The feature shouldn’t follow a particular standard but provide a generic way to draw conical threads.

Hi,

There are 2 sub-issues at this: 1 ) Cosmetic Thread 3d is based on cylindrical (parallel) threads only at this moment. The taper thread needs more and different parameters and it is not as easy to mix it with cylindrical ones. At this moment, I think there could be better to make separate Cosmetic Thread 3D Tapered functions later. 2) Add more types of parallel threads than just Metric coarse. For example metric fine - different pitch, whitworth thread, pipe parallel threads, US threads, trapezoidal threads, ... I totally agree. In the future when the core function is finished.

The BSP threads were mentioned as an example only. I could have created an issue to add them but it’s certainly on your todo list. #18 was to prepare for non-metric thread.
