steps in constructing an isometric drawing

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.
