Drawing Basics - Line Weights on Elevations

In a previous post we talked about how important it was to have line weights to to help communicate information on your drawings. This also applies to your elevations. When I was taught to draw I was taught to use different line weights on elevations to help people to read the elevations. What this means is that there should be a hierarchy of line weights that help people understand what parts of the project are projecting forward and what parts are in the background.
