LI NE QUALI TY
Line quality refersto the crispness, clarity, and
consist ency of adrawn line.
• The density and weight of alineshould be as
uniform as possible along its entire length.
• Drafted lines should have ataut quality, as if
etween two points.

When lines stop short of acorner, the resulting

output from aprinter or plotter.
• The lines produced by vector drawing programs are
based on mathematical formulas and usually print
or plot better than those of raster images.
