Postscript to Parameter Grouping in Revit

Following my earlier post on the sort order of parameter grouping, here is another weird sort order issue:

There is a grouping that exists in the family editor (not in Global Parameters) called “Analytical Properties”.  I am not sure if it exists for all categories but it is there for Windows.  However, it is not available for us to use – it does not show in the grouping list when creating a new parameter.  It is populated with some built-in (system) parameters that we cannot change, although the alphabetic sort order does work on the parameters within the group, as does the Move Up/Down function.

There is a small hint of alphabeticality about it though:  it does slot in just below ‘Analytical Model’, even if above ‘Analytical Alignment’.
