Question:hi, i need architects or furniture makers 2 suggest a prgram for 3d modeling, something simple?

i'm a furniture maker
i work with wood
and i need a program in which i could type in the dimensions of my next project and it can show me what it would look like, so i dont have to build it and then figure out that i'm short couple of inches, or that i went over the top
i dont need a spaceship kinda program just something medium, good enough to tell me what it would look like and maybe to allow me to rotate it in couple of different angles

Answers:
we create our design models in Archicad program - its simple and clever
