Organiziing information with layars AutoCad Help

Another tool for organization is the layer. Layers are like overlays on which you keep various types of information (see Figure 4.12). In a floor plan of a building, for example, you want to keep the walls, ceiling, plumbing fixtures, wiring, and furniture separate, so you can display or plot them individually or combine them in different ways. It’s also a good idea to keep notes and reference symbols about each element of the drawing, as well as the drawing’s dimensions, on their own layers. As your drawing becomes more complex, the various layers can be turned on and off to allow easier display” nd modification.
For example, one of your consultants may need a plot of just the dimensions and walls, without all the other information; another consultant may need only a furniture layout. Using manual drafting, you would have to redraw your plan for each consultant. Wit~1AutoCAD, you can turn off the layers you don’t need and plot a drawing containing only the required information. A carefully planned layeringscheme helps you produce a document that combines the different types of information needed in each case.
Using layers also enables you to modify your drawings more easily. For example, suppose you have an architectural drawing with separate layers for the walls, the ceiling plan, and the floor plan. If any change occurs in the wall locations, you can turn on the ceiling plan layer to see where the new wall locations will affect the ceiling,
and then make the proper adjustments. AutoCAD allows an unlimited number of layers, and you can name each layer anything you want.
