Trace Large PDF
 

I've made a PDF of a large ACAD file. I placed this image in an OG project. Then I'm tracing several of the shapes from the PDF. However, each time I draw a line, move or zoom it takes about 10 - 15 sec for the action to occur. Is this because I've brought in a large PDF and/or is there a way to speed things up?
Thanks,
Gary
