I have tried converting a rater complicated jpeg picture as a vector image and it never goes well... so I am tracing it by hand. But, because I can't make the jpeg part of autocad, I can't change it's location on my computer (path, yes?) AND it often causes autocad 2018 for mac to crash, and then reopening the file, which is now locked is a massive, massive pain... and takes far too much time. =(
