So, does anyone know how to get a linear dimension arrow to be replaced with a properly sized circle to properly show a dimensional limit related to an origin?  (I'm not talking ordinate dims...I'm talking standard linear dimensions).  See figure 2.5 of the ASME Y14.5M-2009 for more detail.   Essentially, the arrow along the origin is replaced with a large circle.  There is a small circle available in the list of arror replacements under dim properties, but it is too small to use as an origination signifier ( and I cannot find any way to adjust its size).
