I have always found the "old" power draw cad excellent, I have upgraded to POWER CADD and that is even better. I do all my 3D (shaping, testing, and rendering) work in Mac surf and have used it since 1989, I have found it to be "EXCELLENT", far and away better than the next - distance - 2nd best. BY using power cadd to draw out a cat hull in conventional plan elevations and perspective it gives me great results and I can loft from those drawings enabling me to set out and construct the boat/hull.
