NX Differences between two types of drawing template parts provided by Siemens

There are two types of template parts for each size in the NX installation folder (example: ~NX2212\DRAFTING\templates). I opened them up and looked at their contents, and they look the same. Is there any difference?

Reproduced Steps:

1. Open “Drawing-A4-Size-template.prt” and “Drawing-A-Size2D-template.prt” and compare them.

The two types of template parts Siemens provides has the same content, but are used differently depending on NX command used.

“Drawing-A4-Size-template.prt”

　 -  Used when "Reference Existing Part" is selected when creating a new drawing (File > New > Drawing tab)   **(1)

“Drawing-A-Size2D-template.prt”

　 -  Used when "Stand-alone Part" is selected when creating a new drawing (File > New > Drawing tab)   **(2)

　 -  Used when creating a new sheet with New Sheet command   **(3)

"ugs_drawing_templates.pax" specifies the template part that will be used when **(1) and (2) are executed. "ugs_sheet_templates.pax" specifies the template part that will be used when **(3) is executed.
