About Linetypes
In a typical drawing, you find linetypes associated with many objects. While the specific linetypes
used may vary from one discipline to another, the concept of using linetypes remains consistent. They
are always used to distinguish objects from one another and to make the drawing easier to read and
understand.
The following illustration contains continuous, hidden, and center linetypes. Each of these linetypes
have meaning within the discipline in which they are used.
Linetypes Defined
Linetypes are an attribute of an object that determines how it looks. The linetype helps to distinguish
oneobject from another in adesign. For example, a hot water linecould berepresented by the HW
linetype and a gas line in a building could be represented by the GASlinetype.
This image shows common linetypes used in drafting and design.
