I have not been able to adjust the line weights of text placed with Arial font via IPLOT is there a way to do this?
There is not a way to change the weight or thickness of a True Type Font in MicroStation or using InterPlot. A workaround is to use a non-TT font, or use a Design Script to change the font to a MicroStation font at plot time.
The following Design Script example changes all Arial fonts to Engineering fonts and assigns weight 0.
if (font_name == 'Arial') thenfont_name = "Engineering"weight = 0endif
