Please recommend a "Pro" Math/Geometry/Physics drawing program (please read inside)

I am already know about Geometers SketchPad - I need something better - something in the MathCAD/MathLAB/AutoCAD class - something for the pros!

I need to do some relatively complicated geometry and physics (and other) drawings (sometimes a 3D geometry drawings) and I need a powerfull tool for it - I don't think that Geometers SketchPad (v3) cut it - I have the SmartSketch demo, can someone recommend another program?

Thanks

You don't like MathLab??? Or you want something better???

MathLAB is awsome - for simulations and the like... but not for drawing stuff (or am I missing smth. really big here - in which case I am a big moron - going to check)

Will a 3D CAD package do what you need? I really like TurboCAD v8 It's about $80

Mathematica?

My knowledge of this kind of software is very limited but, why don't you use two software at the same time like a duo MathLab/Autocad...?

Since I don't have MathLAB currently installed, I must ask -- Does it really does sketches? - I thought it is a simulation software.
