Alphabet Of Lines The backbone of drafting

Introduction to the Alphabet of Lines In order to understand what the drafter is trying to get across, you must be able to understand the symbols and lines he uses. Each line has a definite form and line weight.

5 Main Line Types Visible Hidden Center Dimension Extension

Visible Lines Dark, heavy lines. Show the outline and shape of an object. (SHOWS SHAPE) Define features you can see in a particular view.

Hidden Lines Light, narrow, short, dashed lines. Shows the outline of a feature that can not be seen in a particular view. Used to help clarify a feature, but can be omitted if they clutter a drawing.

Center Lines Thin line consisting of long and short dashes. Shows the center of holes, slots, paths of rotation, and symmetrical objects.

Dimension Lines Dark, heavy lines. Show the length, width, and height of the features of an object. (SHOWS SIZE) Terminated with arrowheads at the end.

Extension Lines Used to show the starting and stopping points of a dimension. (SHOWS LOCATION) Must have at least a 1/16 th space between the object and the extension line. Extension Line Dimension Line

Summary Now that we have discussed the 5 main line types, you should be able to do the following: 1. Identify the alphabet of lines. 2. Identify where the line types are used. 3. Produce the lines with correct spacing and line weight.
