Two Control Parameters are provided, Type of Doc Management, to control the sequencing of Revision Codes on Drawings
Original Drawing
Some users do not want the original drawing to have a Revision Number (i.e. it can be Null).
The Control Parameter 'Default Initial Drawing Revision Code' controls this. With no value in this Control Parameter, a new drawing will by default not have a Revision Code. One can be manually added. If the Control parameter has a value (e.g. A), then this value will be the Revision Code on the original drawing
Subsequent Drawing Revisions
The Control Parameter 'Default Subsequent Drawing Revision Code' (values A to Z, 0 to 9) contains the default for the first Revision of the drawing.
Examples:
'Default Initial Drawing Revision Code' has no value; first drawing will have no Revision Code
'Default Subsequent Drawing Revision Code' has value A; first Revision of the drawing will be A
'Default Initial Drawing Revision Code' has value A; first drawing will have Revision Code A
'Default Subsequent Drawing Revision Code' has value B; first Revision of the drawing will be B
Note that duplicate Revision Codes for the same Drawing are disallowed
