Steps in constructing an isometric drawing

1. 1. STEPS IN CONSTRUCTING AN ISOMETRIC DRAWING
2. 2. 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.
3. 3. 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.
4. 4. STEP 3  Draw the “box” or the crate lines. Use light lines only.
5. 5. 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.
6. 6. STEP 5  Check the accuracy of your drawing.
7. 7. STEP 6  Trace the visible edges with heavier lines.
8. 8. STEP 7  Label the isometric view.
9. 9. POINTS TO REMEMBER WHEN MAKING ISOMETRIC DRAWINGS
10. 10. POINT 1  In drawing your isometric axes, they must be equally distanced at 120°.
11. 11. POINT 2  All isometric lines must be parallel to the isometric axes.
12. 12. POINT 3  Locate first the outstanding edges, corners, and surfaces before analyzing the figure.
13. 13. POINT 4  Use Light lines in sketching the details.
