Example: Displaying Tapered Threaded Holes in a Drawing
Consider the following model with a countersunk threaded and tapered hole.
You can represent the hole in the JIS, ANSI, and ISO standards as discussed in the following sections.
JIS Standard
To display a threaded hole according to the JIS standard, set the thread_standard Detail option to std_jis and the hlr_for_threads configuration option to yes. The following table illustrates the display of the hole in the Wireframe, Hidden, and No Hidden display states:
Display State | Display |
|---|---|
In the Wireframe display state, the cosmetic thread quilt is highlighted in purple. |  |
In the Hidden display state, the cosmetic thread quilt is not displayed. The side and the section views display incomplete threads. The top view displays a 270 degree arc at the outermost major diameter. Solid arcs are displayed for the outermost and innermost minor diameters. The display of the major diameter is blanked at the base. |  |
In the No Hidden display state, the cosmetic thread quilt is not displayed. The side view does not display any holes. The top and the section views are the same as the hidden line view display. |  |
ANSI Standard
To display a threaded hole according to the ANSI standard, set the thread_standard Detail option to std_ansi and the hlr_for_threads configuration option to yes. The following table illustrates the display of the hole in the Wireframe, Hidden, and No Hidden display states.
Display State | Display |
|---|---|
In the Wireframe display state, the cosmetic thread quilt is highlighted in purple, with the major and minor diameters displayed at the base due to the taper. |  |
In the Hidden display state, the cosmetic thread quilt is not displayed. The top view displays solid arcs against the outermost and innermost minor diameters. A gray solid arc is displayed only for the outermost major diameter. The innermost major diameter is blanked. |  |
In the No Hidden display state, the cosmetic thread quilt is not displayed. The side view does not display any holes. The top and the section views are the same as the display of the hidden line view. |  |
ISO Standard
To display a threaded hole according to the ISO standard, set the thread_standard Detail option to std_iso and the hlr_for_threads configuration option to yes. The following table illustrates the display of the hole in the Wireframe, Hidden, and No Hidden display states.
Display State | Display |
|---|---|
In the Wireframe display state, the cosmetic thread quilt is highlighted in purple, with the major and minor diameters displayed at the base due to the taper. |  |
In the Hidden display state, the cosmetic thread quilt is not displayed. The top view displays solid arcs for the outermost and innermost minor diameters. A gray solid arc is displayed only for the outermost major diameter. The innermost major diameter is blanked. |  |
In the No Hidden display state, the cosmetic thread quilt is not displayed. The side view does not display any holes. The top and the section views are identical to the display of the hidden line view. |  |
 | In all the standards, if a tapered thread does not extend to a surface, point, or an edge, the major and the minor diameter arcs are blanked for the additional geometry. |
