Has anyone used both programs enough to give any opinions. I own Designcad and I'm pretty happy with it, but I would like to have Associative dimensioning - the capability that dimensions automatically re-adjust when you resize an object. Turbocad has this capability but its a bit overwhelming to learn. The sales people say its more of a professional grade program and I will have a much steeper learning curve. I'm willing to go through that if it will result in the same capabilities of DesignCad with associative dimensioning. I really, really like the 3D modeling capability in Designcad and assume that Turbocad can so just as well.
