### Transcript

• 1. Given the end elevation of abook with pages A, B, C, D, Eand F open at thirty degrees toeach other.
• 2. Draw in the elevation of thebook bringing constructionlines from the end view.
• 3. Draw the plan of the open book.
• 4. Draw in the picture plane andthe spectator point.
• 5. Draw in the horizon line andthe ground line.
• 6. From the station point, draw a lineparallel to the side of the bookuntil it strikes the picture plane.
• 7. From this point, perpendicular tothe picture plane drop a line downto the horizon line to establish theright-hand vanishing point.
• 8. Repeat the previous steps toestablish the left-hand vanishingpoint.
• 9. Next we have to find the auxiliaryvanishing points.As pages F and B are inclined atthirty degrees, draw a line at thirtydegrees to the parallel line thatestablishes VPR.
• 10. From the parallel line thatestablishes VPR, draw a lineperpendicular to it where it strikesthe picture plane.
• 11. Record the distance h and step itoff with a compass directly aboveand below VPR to establish AUXB and AUX F.
• 12. We can see that pages E and Care inclined at sixty degrees.
• 13. As pages E and C are inclined atsixty degrees, draw a line atsixty degrees to the parallel linethat establishes VPR.
• 14. Again draw a perpendicular lineat the picture plane.
• 15. Record the distance k and step itoff with a compass directlyabove and below VPR toestablish AUX C and AUX E.
• 16. Now we can see four auxiliaryvanishing points.
• 17. As this corner of the booktouches the picture plane it is atrue length in perspective.
• 18. Connect this corner inperspective to the two vanishingpoints to establish the front twosides of the book.
• 19. Draw lines of sight from thespectator to the two outer cornersof the book in plan.
• 20. Where these lines of sight cut thepicture plane drop vertical lineswhich will establish the outline ofthe book in perspective.
• 21. Bring lines of sight back to bothvanishing points from the outeredges of the book.Join page F in plan back to the spectator point.
• 22. Draw two lines parallel to thepicture plane where these linescut.
• 23. Auxiliary vanishing point F is usedto draw page F in perspective.
• 24. The exact same thing is done forpage E. Join page E in plan backto the spectator point.
• 25. Again draw two lines parallel tothe picture plane where these linescut.
• 26. Like page F, auxiliary vanishingpoint E is used to draw page E inperspective.
• 27. Draw in page E.
• 28. Page D is drawn simply as itdoesn’t need an auxiliaryvanishing point.
• 29. Pages C and B are drawn usingthe exact same procedure aspages E and F.
