USING LINES TO
PRODUCE VOLUMES

AGENDA
Line drawings present themselves in
several ways including outlines of objects,
movement or density of objects and even
erasing. It is common for artists or
illustrators to use various line drawings as
a warm-up, oftentimes giving them fresh
ideas on how to begin working on a longer
study.

AGENDA
A line drawing as a final work of art,
typically does not capture all the
information of the object being drawn,
instead it usually only captures one
characteristic, either the interior or the
exterior. Charcoal, pencil, ball point pen,
Chinese ink and black markers can all be
used to practice line drawing techniques.

A line in art is defined as a point moving in
space, and it is one of the seven elements of
art (line, color, shape, form, texture, value,
space). It is one of the most crucial elements,
as everything begins with just a simple dot in
space, that transforms into lines and then
drawings.
Vertical lines are straight up and down lines
that are moving in space without any slant and
are perpendicular to horizontal lines. They
suggest height and strength because they
extend towards the sky and seem
unshakeable.

Horizontal lines are straight lines
parallel to the horizon that move
from left to right. They suggest
width, distance, calmness, and
stability.
Diagonal lines are straight lines that
slant in any direction except
horizontal or vertical. When in use,
they suggest movement or lack of
stability.

Zigzag lines are a series of diagonal
lines joined at ends. They can convey
action and excitement, as well as
restlessness and anxiety.
Curved lines are lines that bend and
change direction gradually. They can
be simply wavy or spiral. Such lines
convey the feelings of comfort and
ease, as well as sensual quality as
they remind us of the human body.

HOW TO GET VARIATIONS OF
LINES IN ART?
THE 5 MAIN TYPES OF LINES ARE THE
BEGINNING OF ALL SORTS OF AMAZING AND
UNIQUE LINES! TO GET MORE LINE VARIATIONS,
REFER TO TOOLS SUCH AS LENGTH, WIDTH, WEIGHT,
TEXTURE, STYLE, DIRECTION, THE DEGREE OF CURVE
OR ALL THE ABOVE COMBINED.

The "alphabet of lines" in technical drawing
refers to a set of standardized line conventions
used to represent different features of an
object. These lines, each with a specific
meaning and appearance, help convey
information clearly and accurately in technical
drawings. Key line types include visible lines,
hidden lines, centerlines, dimension lines, and
cutting plane lines.

Here's a breakdown of some important line
types:
Object/Visible Lines:
Thick, dark lines used to show the visible edges
and outlines of an object.
Hidden Lines:
Dashed lines used to represent features that are
not visible in a particular view.
Centerlines:
Thin, alternating long and short dashed lines

Dimension Lines:
Thin lines with arrowheads at each end, used to
indicate the size of a feature, with the actual
dimension value placed near the line.
Extension Lines:
Thin lines that extend from the object to the
dimension line, helping to define the extent of
the dimension.
Cutting Plane Lines:
Thick dashed lines with arrows, indicating where
an object has been "cut" to create a sectional

Section Lines:
Thin lines drawn at an angle, used to show the
material exposed by a cutting plane.
Phantom Lines:
Thin, long-dashed lines with two short dashes,
used to indicate alternate positions or repeated
features.
Understanding and correctly applying the
alphabet of lines is crucial for both reading and
creating technical drawings.
