Print Reading Unit 2

A thick, continuous line representing all of the edges and surfaces that are visible in view. should be twice as thick as the thin lines within the view.

A line that features a thin, short dashes spaed closely together. dashed are 1/8" long and spaced 1/32" apart.

designate centers of holes and arcs, symmetry, and paths of motion. Thin broken line, alternating long and short dashes.

Used to show that an object is symmetrical about a center line. Thick, short contiuous line.

Used to represent the surfaces of objects that have been "cut" to show interior detail. Thin continuous lines, most drawn at 45 degree angles.

Indicate where the cut in a part is to be made. Thick dashed lines that terminate with arrowheads. Lieeters may be used to inentify the section.

Extend the edges of objects out and away fim the view. Thin continuous line begin at .0625 extending .125 beyond deminsion line

Indicate the extent and direction of part dimensions. Thin continuous line terminated by arrowheads. Broken in the middle for the dimension value.

Used to associate a note with a specifc feature or area of a drawing. Thin continuous line that terminates with an arrowhead.

Used to establish viewing direction. identical in appearance to a cutting plane line.

Used to "Break out" or "break off" a portion of a view. two types include: short break (thick, drawn freehand), and long break (thin and continuous).

Used to indicate, alternate positions of moving parts, adjacent positions of related parts, and repeated detail. long dashes alternating with pairs of short dashes. similar to cutting plane line but the line weight is thin.

Represent the path of a stitching or sewing process.

Indicates an area on a drawing where something special applies. similar to a center line but thick instaed of thin.

should be uppercase, 1/8" (3mm) in height. created as single stroke gothic lettering.
