To Show Datum Axes on a Drawing
When you show datum axes the axes of cylindrical and conical surfaces display on the drawing and erases axes that the system shows in a drawing. Because axes are inherited from the model you cannot delete them from within the drawing.
1. On the Annotate tab, in the Annotations group, click Show Model Annotations. The Show Model Annotations dialog box opens.
2. Click .
3. Select the check box in the Show column for datum axes that you want to show. Click OK in the Show Model Annotations dialog box. The set axes are displayed in the drawing.

Showing or erasing an axis in a radial pattern affects corresponding axes in all pattern instances.
The show_preview_default Detail option lets you set the preview tab default to either select to keep or select to remove.
