Polar pattern dimensioning

I am trying to create the polar pattern dimensioning in DimXpert similar to this image I found in Solidworks help.  My question is:

Does anyone know how to create an angular dimemsion, in DimXpert, between two holes (as shown in the attached image)?   Also, how do you dimension the diameter of the pattern holes (the 50mm diameter dimension)?  Any help would be greatly appreciated.  Thanks.
