Question for ID designers.

I don’t know too much about Industrial Design, but I do have a question about some of the works that I’ve seen on this website. Many of you guys are designing very innovating products and showing them to the audience through images. I was just curious when creating your images, are you guys just drawing them though Illustrator (or some other similar program), or do you actually make the object (though cad? 3d model machine, etc?) …and then take a picture of it.


People are using all kinds of techniques, from hand sketching and markers, to digital sketching, illustrator, photoshop, 3d modeling/rendering, and 3d working/appearance prototypes made by hand, rapid prototype process, or actual production runs.
