The Envelope, Block In and Proportions.

I did some quick researching online to find some more examples of the "Envelope" method we have been using in class.  This is very clearly illustrated in this little write up by Robert T. Barrett. Enjoy!

Exercise I. Drawing the Human Figure: Using a Simple Block-In

Using an envelope block-in and gridding to measure and map the figure isn’t a new process. Though some examples of gridding may seem complicated or complex, this measuring process is, nonetheless, a useful tool in learning how to draw people.
I suggest using a simple form of gridding to plot points and angles when completing a traditional life drawing because it will help you establish the correct position and dimension of proportional relationships.

1. Drawing the Human Figure : Create an “Envelope” Around the Figure

A first step in gridding the subject is placing an “envelope” around the outside edges of the figure (below). It’s helpful to use only straight lines during this process because landmarks will occur at intersections where the angle of each line changes direction in a drawing of the human figure.

2. Drawing the Human Figure : Plot the Inside Landmarks

After you establish the envelope and create the outside angles and proportions, look for inner landmarks (see below). These are often located at points where two angles intersect or at “hard places” where the skeleton is close to the surface.

3. Drawing the Human Figure: The Finish (see below)

This model for my life drawing class, in Seated Male Figure (Nupastel on paper, 30×22), had great anatomical definition, which made the figure drawing techniques of mapping his figure easier.
