Drawing through your forms

This exercise is all about developing your understanding of 3D space and how forms can be manipulated within it. In order to do this most effectively, we can't be thinking about what we draw as being lines on a flat page, or simple flat shapes. We need to work towards understanding how each form sits in 3D space.

The first step towards this is to draw through our forms. That is, drawing all the edges, including those that we cannot see. Think of it like you have x-ray vision. We already did some of this in lesson 1.

Doing this forces us to understand to a much greater degree how the forms we draw exist in space. You may find it difficult to do so, and may find that often times the "back corner" fails to fit with the rest. This is completely normal. As we draw a box, we regularly make small mistakes in our angles and trajectories of our edges. We compensate for them as we continue to build out our box. This accumulation of mistakes always falls on the lines that have yet to be drawn, and if we're not drawing through them, it becomes quite easy to get by without having to deal with the issues present. Once we draw that back corner however, we're forced to come to terms with our blunders.
