The Suffix property specifies the suffix for a dimension label (that is, the text displayed after the dimension value, symbol, and units).
Examples:
The following VBA example creates a rectangle and a linear dimension that is linked to the rectangle's snap points. A suffix is added to the dimension text.
Sub Test()
Dim shp1 As Shape, shp2 As Shape
Set shp1 = ActiveLayer.CreateRectangle2(0, 0, 5, 2.5)
Set shp2 = ActiveLayer.CreateLinearDimension(cdrDimensionHorizontal, shp1.SnapPoints(1), shp1.SnapPoints(3))
shp2.Dimension.Suffix = "-CNT"
End Sub
