AVEVA font families are defined by their IR (International Registration) number and Style number in the system database. Font file names are of the form marrrtswuu, where m=0; a is the alphabet; rrr is the encoding; ts is the type and sub-type; w is the weight; and uu is a serial number. AVEVA fonts are exported to AutoCAD as either filled (prefix f), or open (prefix of). All font-files have an 8-character equivalent short name:

In addition, DRAW uses a Symbol font for special characters (e.g. ~D gives the degrees symbol). The AVEVA SYMBOL font is of0999911901.shx (shortname OOP11901). The equivalent filled font is f0999911901.shx (shortname FOP11901).
