[quote user="Bruce Reeves SRNS"]I *was* able to get the text font to change after I also set ElementPropertiesSetter::SetChangeEntireElement(true)[/quote]
It would be helpful if the comment in MicroStationAPI help for ElementPropertiesSetter::SetFont() included the hint that 'font' is not one of an element's base properties and therefore that the call to SetChangeEntireElement() is required. One might argue that, for a text element, its font is a fairly basic property.
