Example: Displaying Threaded Shafts and Holes of an Assembly in a Drawing
Consider the following model where a threaded tapered bolt with a leading chamfer is inserted into a countersunk, threaded, and a straight hole.
You can represent such a bolt and hole in the JIS, ANSI, and ISO standards as discussed in the following sections.
JIS Standard
To display a tapered threaded bolt and a hole of an assembly 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 such a bolt and 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. The crosshatch of the shaft overrides that of the hole. |  |
In the Hidden display state, the cosmetic thread quilt is not displayed. The side and the section views display incomplete threads. 270 degree arcs are created but hidden. |  |
In the No Hidden display state, the cosmetic thread quilt is not displayed The side view does not display holes or shafts. The top and the section views are the same as the hidden line view. Hidden lines are not displayed. |  |
ANSI Standard
To display a tapered threaded bolt and a hole of an assembly 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 such a bolt and 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. Crosshatches of the bolt and the hole overlap. |  |
In the Hidden display state, the cosmetic thread quilt is not displayed. Solid gray arcs are displayed for all the threaded major and minor diameters. |  |
In the No Hidden display state, the cosmetic thread quilt is not displayed. The side view does not display holes or shafts. The top and the section views are the same as the hidden line view. Hidden lines are not displayed. |  |
ISO Standard
To display a tapered threaded bolt and a hole of an assembly 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 such a bolt and 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. Crosshatches of the bolt and the hole overlap. |  |
In the Hidden display state, the cosmetic thread quilts are not displayed. 270 degree arcs are created but hidden. |  |
In the No Hidden display state, the cosmetic thread quilt is not displayed. The side view does not display holes or shafts. The top and the section views are identical to the hidden line view. Hidden lines are not displayed. |  |
