I am trying to teach myself Production design since I can't afford to go to school. I am having difficult time in the techincal drawing in CAD so then I can create the white card model. I know Cad basics, I just can't seem to move to the next step. Can anyone help me, any exercise would be good. I need to draft the layout and then the elevations? I am really lost and any help would be appreciated. Any easy beginner exercise would help tons too.
