Appendix 3 Color, Linetype and Line Weights

SETTING THE COLOR, LINETYPE AND LINE WEIGHT OF AN OBJECT

AutoCAD provides the facility to control the properties of an object such as color, linetype, line thickness, and so on, as per the requirement of the user. At times it may be essential to assign different colors to different objects in the same layer so that the understanding of the drawing is improved. There are instances when it is necessary to specify a fixed color for a layer to have all the objects drawn on that layer look alike.

You may also use different line types in your drawing to represent object outlines, hidden lines, center lines, and so on. The linetypes are controlled by setting the same in AutoCAD. Similarly, you can adjust ...
