I have used SW myself and the best method (I made up this method when I made plans for my USS Zellars ) I have found is to get the plans in as good a shape as possible and import them into SW. In SW, set up your perpendiculars, length, breadth and framing, any dimensions that you actually know be it from the plans, offsets, or contract. Then import your plans, to avoid making SW file huge, if you are able, import the plans in pieces, trace over them or redraw them however you wish, when your confidence is high and you are pleased with the results, remove the plan images, they just clutter up the file anyway or keep those that you want.
Beware of the accuracy demon though, he lurks around every corner and can drive you mad. SW allows you to model things very accurately. At 1/4" = 1 ft, a 1 inch difference is about .02 in real model inches. By the time you start cutting wood and sanding, .02 or .03 is normal. In fact. 06 is about 3 inches. So guage your accuracy accordingly.
