We currently work primarily in imperial units. However, there are several occasions when we wish to have a imperial sized hole in the model and wish it to be toleranced ie dia 3.5mm +0.5mm -0.2mm. As we wish to keep the model correct, these figure, ie the hole diameter, plus tolerance and minus tolerances can be input into the dimension properties and given their equivalent imperial sizes. We can then convert these imperial dimensions into metric parameters, ie M_HOLE=d22*25.4, M_HOLE_PLUS=tp22*25.4 and M_HOLE_MINUS=tm22*25.4. However, when used in an annotation note in the drawing, the M_HOLE can be used in the note with the syntax of &M_HOLE but when we enter the superscript and subscript mode using @+ @# and @- syntax, the M_HOLE_PLUS and M_HOLE_MINUS parameters appear as just text. It would be very useful if the parameter values were shown in the superscript and subscript portions of the drawing note, so that the model and the drawing were in sync.
