Dave R, yes I did use AA on export. I notice you are using a sketchy style for the overlay example you provided whereas I am trying to use straight clean lines for the dimensions. When I try the method using double the scale and then reducing the image, the lines are still jaggy, even after AA in post pro.
Gaieus, at the risk of sounding ignorant what do you mean by resampling? Do you mean scaling the image back down?
Thanks guys
