Drawing for dummies?

Hi !
I was wondering if anyone could advise me on a good book to help me with my 3d sketching. I am fine with 3d cad like sudiomax etc but have a hard time drawing stuff. As a furniture designer, I feel shameful…
Can anyone help with a good book?

I found this in Amazon but it looks tacky :

Mark Kistler’s Imagination Station: Learn How to Draw in 3D with Public Television’s Favorite Drawing Teacher! - Mark Kistler;

Drawing Shortcuts: Developing Quick Drawing Skills Using Today’s Technology

Looking forward to good books !
