I don't think I'd give up ACAD....been using it for the past 15 years..there is a reason the majority of architectural firms use it....3d is a pain in the ass with it.....but lately i've been using sketchup for schematic 3d design, can't beat the price and results; .02 from a registered architect who uses ACAD daily for CD's and client presentation
