Drawing with pencil,...black marker over papier.

The begin from these Study-Drawings, was the 3d Sketchup Model,after I have continue in others Programmas.

But Sketchup was the beginen to understand that original form.

After that, was different steps of drawings.

I WAS INTERESTED TO CONTACT THE AUTHOR “ZIPPO”IN THE WAREHOUSE SKETCHUP SITE (BUT THAT WAS NOT SIMPlE TO FIND HIM ).

I don’t understand these step in sketchup warehouse ( can you help me ?), Obviously I have made a design,from these model, but I was visiting these City,in 2010.

(In the beginen I thought to make myself one 3d Model, but I have found one in these site and that was a great help to me in these Process).

Sure that is not a ClassicTutorial, Step for Step, but maybe a “Process of Drawings”.

Since Sketchup !.
