In Autodesk® Revit®, numbering is by default realized through increments. Consequently, numbering becomes inconsistent after elements are deleted or added. When you want to insert elements, numbering always needs to be corrected by hand.
NuPAutoNum for Autodesk® Revit® enables automatic numbering of Revit elements. By pre-filtering, you may define which category or family type the Revit element to be numbered is supposed to be assigned to. You can further limit the preselection by predefined parameter values. Additionally, you can choose from several ways of numbering (figures, letters, as well as with prefix or suffix). It is moreover possible to analyze an existing numbering to check, for instance, whether it is gapless.
