Axis Display Options
By setting the Detail option axis_interior_clipping to no, you can set the axis display according to these three ANSI Y14.2M standard requirements:
• Line starts and ends with a dash.
• Perpendicular axes of a centerline intersect at a short dash.
• Very short centerlines are unbroken.
Axes that are set to CTRLFONT actually are shown as CTRLFONT_S_L or CTRLFONT_L_L, depending on their orientation. You can control them by setting line_style_length to CTRLFONT_S_L or CTRLFONT_L_L, not CTRLFONT. To control axes that are perpendicular to the view, set line_style_length to CTRLFONT_S_L; to control axes that are parallel to the view, set it to CTRLFONT_L_L.
This option affects the axis display in the following ways:
• Axes parallel to the screen appear in one line in a centerline font, beginning and ending with a long dash.
• Axes perpendicular to the screen appear in two lines, each of them drawn in two segments.
• Perpendicular lines intersect at a short dash.
• When any axis is too short, it appears in a solid line font.
Using the Detail option radial_pattern_axis_circle, you can set the display mode for axes of rotation that are perpendicular to the screen in radial pattern features. When you set the option to yes, a circular shared axis appears, and the axis lines pass through the center of a rotational pattern. However, this only affects patterns that you create using the Dim Pattern command.
The following restrictions apply when you set this Detail option to yes:
• You cannot move, clip, or modify the line style of a circular shared axis that appears once you choose to show from the Show Model Annotations dialog box (accessed by clicking on 
Show Model Annotations in the Annotations group, of the Annotate tab).
Show Model Annotations in the Annotations group, of the Annotate tab).• In a clipped view, the system only displays portions of lines and circles that are inside a view boundary.
• You cannot use radial patterns of group features.
• You cannot show radial pattern axis circles for reference patterns.
