The document outlines the 7 steps to construct an isometric drawing: 1) Draw the three axes at 30 degrees, 2) Plot the principal dimensions of Height, Width, and Depth, 3) Draw the outer lines of the object lightly, 4) Add the internal details by analyzing points, 5) Check the accuracy, 6) Trace visible edges with darker lines, 7) Label the drawing. It also lists 4 key points to remember like keeping axes equally spaced at 120 degrees and using light lines initially.
Steps in constructing an isometric drawing
- 1. STEPS IN CONSTRUCTING AN ISOMETRIC DRAWING
- 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. 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. STEP 3 Draw the “box” or the crate lines. Use light lines only.
- 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. STEP 5 Check the accuracy of your drawing.
- 7. STEP 6 Trace the visible edges with heavier lines.
- 8. STEP 7 Label the isometric view.
- 9. POINTS TO REMEMBER WHEN MAKING ISOMETRIC DRAWINGS
- 10. POINT 1 In drawing your isometric axes, they must be equally distanced at 120°.
- 11. POINT 2 All isometric lines must be parallel to the isometric axes.
- 12. POINT 3 Locate first the outstanding edges, corners, and surfaces before analyzing the figure.
- 13. POINT 4 Use Light lines in sketching the details.
