STEPS IN CONSTRUCTING AN ISOMETRIC DRAWING
STEP 1 Draw the three axes using triangles as light as
possible. Be sure the cross axes are about 30° from the lower edge of the paper.
STEP 2 Plot the principal dimensions, Height (H) on the
vertical axis, Width (W) on the left 30° axis, and Depth (D) on the right 30° axis. Get the measurements from the orthographic views.
STEP 3 Draw the “box” or the crate lines. Use light lines
only.
STEP 4 Draw the details of the object by analyzing the
figure and determining the points in relation to other points representing the corners, surfaces, and edges.
STEP 5 Check the accuracy of your drawing.
STEP 6 Trace the visible edges with heavier lines.
STEP 7 Label the isometric view.
POINTS TO REMEMBER WHEN MAKING ISOMETRIC DRAWINGS
POINT 1 In drawing your isometric axes, they must be
equally distanced at 120°.
POINT 2 All isometric lines must be parallel to the
isometric axes.
POINT 3 Locate first the outstanding edges, corners, and
surfaces before analyzing the figure.
POINT 4 Use Light lines in sketching the details.
