About Displaying Tapered Threaded Holes in a Drawing
You can display tapered threaded holes in a drawing in the standard and cross-section views according to the JIS, ANSI, and ISO standards. To display such holes, use the thread_standards Detail option in conjunction with the hlr_for_threads configuration option.
The following figure is a simplified representation of a tapered threaded hole displayed as concentric circles overlaid on a detailed model:
1. Outer diameter of the countersunk hole
2. Innermost minor (drilled hole) diameter
3. Outermost minor diameter (hard geometry)
4. Major diameter of the thread at the outermost intersection surface
5. Arc for the thread from the major diameter at the base
6. Incomplete threads
