About Modifying A Z-radius Dimension
You can drag the draggers available at the following locations to modify the size and shape of a Z-radius dimension:
z
The attachment point on the selected arc — You cannot drag the attachment point along the arc. You can drag the entire first segment of the dimension line. During the dragging, the normality of the segment to the geometry is preserved
Along the sides of the dimension text — You can reposition the dimension text along the first segment. You can also place the dimension text on the opposite side of the arc. However, you cannot drag the dimension text beyond the first center angle of the dimension or place the text in a position other than along the first segment of the dimension.
The first center point — This represents the end point of the first segment. You can drag this point to change the position of the first center point of the Z-radius dimension. The movement of this dragger is restricted along the direction of the first segment, that is always constrained normal to the selected arc, and to the extent of the imaginary center point on the opposite side.
The second center point — This represents the start point of the third segment. The imaginary center of the arc is at the opposite end of the third segment. The movement of this dragger is restricted along the direction of the third segment, to the extent of the imaginary center point on one side, and to the arrow head tip (attachment point) on the opposite side.
The imaginary center of the arc—You can reposition the imaginary center, change the termination symbol, or edit the attachment of the imaginary center. If you place the imaginary center over a geometric entity, the movement of the dragger is restricted along the geometric entity. The movement of this imaginary center point is limited on one side of the jog line, to the extent of the start point of the jog line.
 
* The dragging movement of any of the segments, or that of the center point, will always maintain parallelism between the arrow line segment and the jog line of the imaginary center point.
You can change the Z-radius dimension termination symbol to a filled dot or a cross symbol or not have a termination symbol.
You can set the value of the default_z_radius_center_symbol Detail option to specify the default termination symbol of a Z-radius dimension. If you place the imaginary center of the arc on a geometric entity, the default termination symbol of the dimension appears as a filled dot irrespective of the value you set for the default_z_radius_center_symbol Detail option. However, if you choose a free point within the drawing to place the imaginary center of the selected arc, the default termination symbol is the type defined by the Detail option.
You can set the values of the draw_dot_diameter and draw_arrow_width Detail options to set the default diameter of the filled dot termination symbol and the arrowhead of the Z-radius dimension.
The cross termination symbol of the Z-radius dimension appears with a size of 5 mm by 5 mm or an equivalent value in English units. The line style of the cross symbol is solid font with the color similar to that of the dimension text.
 
* You cannot change the size of the cross termination symbol of the Z-radius dimension.
You can modify the arrow style of the arrowhead of the dimension. To modify the arrow style, select the arrowhead of the dimension, right-click, click Arrow Style on the shortcut menu, and specify the required arrow style.
