The ability to turn your background drawing into gray if you want (VERY handy for Furniture Plans, RCPs, etc. GROUPS (HOORAY!!!! God i miss these, they make drawings SO MUCH EASIER) Two quick things VW has over autocad, that we haven't mentioned yet : in VW, everything is scaled automatically to whatever scale you set it to, voila! (And why shouldn't it be?! IT'S A COMPUTER, it's MADE to do conversion fractions automatically!!!) For example I spent a good chunk of today just messing around trying to get my xref'ed linetypes to read correctly on my scaled paperspace sheets-I had to run testplots and everything. Once you've done it a simpler, easier way it is way hard to go back to autocad. Yes the whole paperspace / xref bullshit drives me nuts. i tried the white background for about 2 seconds until i lost all the yellow and white lines. and autocad does nothing if not rope you into getting stuck doing the same conservative action for years! you know how it goes.
Because it was all originally set up for colors on a black background, way back when. Yeah, I would do that, except that then I can't see the office layer colors that we have to draw in.
