Visual C++

[ObsoleteAttribute(L"This property is obsolete as of Revit 2016. Use GetAlphanumericRevisionSettings or SetAlphanumericRevisionSettings instead.")]
public:
property String^ RevisionAlphabet {
	String^ get ();
	void set (String^ value);
}

Remarks

Individual revisions may be set to use alphabetic numbering rather than numeric. This property determines the characters assigned to the alphabetic revisions. The characters in this string will be assigned to revisions in the same order that they appear in the string. If there are more alphabetic revisions than characters in this string then subsequent alphabetic revisions will be assigned duplicated characters. For example, if the string provided were "XY", the first alphabetic revision would be shown as "X", the second as "Y", the third as "XX", then "YY", "XXX", etc.

This string may not contain any whitespace, numeric characters, or duplicated characters. It also may not be empty.
