I'm looking for a program that i can use to do 3 dimensional drawing of the things i listed above. something that i can draw 3 view and 3d drawing of things i want to build and design.
i do have a small background in architecture, but want something on the computer that i canuse.

something with a learning curve that isn'thtat high, but can expand later as a learn....

any advise?

i use Autodesk Inventor 8 Professional. Its super user friendly and easy to work with. I have a full seat of it if your interested. I won it at a machinist competition. Brand new only installed once to see if it would work on my machine. Unfortunately it didn't. If your interested i'll take $350 shipped. I have no use for it. Retail is about $550
