CONSTRUCTING AN ISOMETRIC DRAWING
STEPS
1. Analyze the orthographic
view. Imagine what the
figure would look like in
3D/Isometric view.
STEPS
2. Using a T-Square, create
a horizontal line parallel to
the edge of the paper.
STEPS
3. Locate the midpoint of
the horizontal line, and
draw a vertical line
perpendicular to the
horizontal line, again,
using the T-Square.
STEPS
3. Using the 30° angle
side of your triangle, draw
the right 30° cross-axis
from the converging point
of
the
vertical
and
horizontal line by placing
your triangle on top of your
T-square laid horizontally
STEPS
4. Repeat step 3, now on
the left side of the
vertical axis
STEPS
5. Look back on the
orthographic
view
and
determine the measurement
of the width, height, and
depth of the object.
WIDTH
DEPTH
HEIGHT
STEPS
6. Determine the axes’
corresponding dimension
from the orthographic
views.
STEPS
7. Measure the width,
height, and depth from
the converging point of
the axes and plot the
point on the axes.

8. From the plotted point
on the Left 30º CrossAxis, using the triangle
placed on top of the TSquare, draw a vertical
line extending higher
than the plotted height
point on the vertical axis.

STEPS
9. Repeat step 8 on the
Right 30º Cross-Axis

STEPS
10. From the plotted point
of height, using the 30º
angle, slide your triangle
until the edge of the
triangle touches the point
on the vertical axis. Then,
draw a line from the point
until it crosses the vertical
line drawn from the depth
point.

STEPS
11. Repeat step 10 on
the left side.

STEPS
12. Using your triangle on
top of your T-Square, slide
your triangle until its edge
touches the intersection
point of the Left Vertical
Edge and Left Horizontal
Edge and from there draw
a line extending longer
than its parallel edge.

STEPS
13. Repeat step 12 on
the right side.

STEPS
14. Start recreating each details of
the views on the isometric drawing.

STEPS
14A. Look back on your
orthographic view and
locate the points of
details per view.

STEPS
14B.
Recreate
the
details per view on the
isometric drawing by
measuring and plotting
the points on each side
of the drawing.
STEPS
14C. For the top view,
slide the triangle until it
touches the points on its
edge and from the points
draw line according to
the top view on the
orthographic view of the
object.
STEPS
As
of
now,
your
guidelines
for
your
isometric drawing should
look like this:
STEPS
15. After recreating the
details of each view on the
isometric drawing, look
back on your orthographic
view, analyze the views
and further give details on
the
isometric
drawing
based on what it should
look
like
in
a
3D
perspective.
STEPS
15. After completing the
details of the isometric
drawing, using a pen,
finalize the drawing by
outlining the edges of the
figure.
Be careful not to outline
guidelines which do not
define the edges of the
figure
