So This week I decided to pick a interior sketch from my sketchbook. The main things I battled with was perspective problems. Its natural to put a curve or jester to a line while you sketch. Gestural lines are great for sketchbooks but don’t translate well in technical drawings. I plan to convert my gestural sketch into more of a technical drawing without losing some of the interesting qualities (line weight, graphic break-up, etc).
First step is to grab some vellum, scan in and clean up your starting sketch and start mapping out my changes. Before you can make changes you have to understand what is wrong the sketch. Simply reflect you sketch in a mirror and all the perspective problems will become apparent.
Below is the roughed out sketch. Right away you may notice the perspective problems, the surfaces that aren’t relating, and a poor sense of depth. So my first task here is to overlay and fix the most noticable problems.
The dashboard was a major factor in this sketch once I set up its position in the foreground. Everthing else relates to it. if you notice, the front driver’s seat is a bit more unrealistic than an actual car interior, but it works for the sketch. In a composition like this where I’m only showing half of the interior, I can cheat in some areas.
Check back tomorrow for part II of the series.
