Displaying Dimensions in Detailed and Partial Views
A dimension that references nonsolid geometric features (axes, datum points, datum planes, and so forth) can be present in a detailed or partial view only when the following requirements are satisfied:
• At least one of the entities being dimensioned must be within the spline boundary.
• This entity must also be within the view boundary of the view—the view boundary is defined by the solid geometry of the part. (Nonsolid geometric features are not considered to be solid geometry.)
Check that these requirements are met before you change a view to a detailed or partial view, or dimensions will disappear from the new view.
The Detail option clip_dimensions affects the display of dimensions in detailed views. When you set it to yes, dimensions that are completely outside of the view boundary do not appear. Dimensions that cross the view boundary appear, and the leader that seems to have no geometric reference appears with a double arrow (>>). To change the arrow style, set the default arrow style of clipped dimensions by specifying a value for the Detail option clip_dim_arrow_style (double_arrow is the default).
