> teaches you to make a cube.
here's the link to the cube tute. this will explain in the simplest terms that i could come up with of the basic binedit workings and construction of 3d bin modeling.

The easiest way to build something in binedit for me, and is how I learned most everything about binedit is to find a model that is close to what you want and rearrange it, reshape it by manipulating verts and faces then adding verts and faces when/if nessesary, resize, reshape, then remap it. That is a lot easier than building something completely from scratch. The only time I do from scratch is when what I want is completely unique to anything out there.
There's a lot of models available as free range subjects to do with what you want, no strings attached...
