The following illustrations will help you understand how to draw a command sheet.
Drawing a command sheet using a diagonal line
The diagonal line method is easy to use for designating rectangular areas. It is also more precise, but it is difficult to use for designating complex areas.
Drawing a command sheet using a closed line
The closed line method is easier to use for complex areas, but it is less precise. It also takes longer to draw a command sheet with the closed line method.
