im the same, but different............
Same, as having my dimension styles set up in my template file.
Different, i use paperspace for all of my dimensions, and buy using DIMASSOC set to 2, sorts out the scale thing.
I have mine set up to an engineering standard AS1100 [ Australian Standard]
where the text.space & arrow size is 2.5mm
i also have styles that have arrows and extensions removed so you only see the text. this is also handy for a text override for things like "equal" and "check on site"
