We use Illstrator and Cadtools to create 2D tech packages for backpacks and other sport related product. We use all the CS4 functions but also need a much better dim. tool. Cadtools has an very weak interface, nothing customizable, can’t add our icons…you get it. I also think Cadtools maybe causing CS4 to crash. I have spoken to both companies but they pretend that nothing is wrong. We found a program from Japan called www.baby-universe.co.jp/en but they don’t support CS4 yet. ALso, don’t know if its good or not. Any help would be great.
