This lesson describes how to add dimensions and spot dimension symbols to a project. You begin the lesson by learning about temporary dimensions, permanent dimensions, and spot dimension symbols. Next, you learn about some recommended practices for working with dimensions and spot dimension symbols. The lesson concludes with an exercise on adding dimensions and spot symbols.
You use temporary dimensions to quickly and accurately locate elements in a model and you use permanent dimensions to annotate the design. Further, you use spot dimensions to locate and annotate the elevation, coordinates, and slope of the structural members in a model.
