< My problem as a RANK beginner is: I do not even know what the terms mean !!! After making a simple brooch, with holes for precious stones usw., I KNOW that I should be able to "Loft" parts of it into 3d levels. But WHAT is "Loft"? How to use it? What is "trim"? "Extend"?

Take a look here (slide the page there is "Surfacing" Lexicon")
