Large Diameter flange diensions

Did anyone have any problems with dimensions of large diameter flanges?

Our flanges are B16.47 Series A , but Caesar is giving different dimensions.
I am using version 2019 SP2

What flange standard the Valve-Flange database defaults to for B31.3 piping ?

Is there something I need to do to get B16.47 Series A dimensions?

Use B16.47 Standard, or Pipe Data Pro to get info faster, what's so difficult?

Moreover, bolts & nuts weight is not always properly considered, so that I suggest to do yourself flange weight definition. It's safer.

...But this does not diminish in no way Caesar II utility and viability...Sometimes user should act, make choices and decisions, and not let the software do everything...that's why engineers and designers still exist, isn't it?
