Currently using AutoCAD 2000, win 98, plotting to a cannon 520. It's a copier/ plotter. Anyhow, I get drawings that were microstation drawings at one time, and then saved out as cad drawings. and some drawings that I plot, plot with the linework greyed out, not black. I've even inserted a layering system that I use on my usual cad drawings and moved all the linework to these layers. Does anyone have these issues. If so please let me know how to fix.
