7. 1. Set Picture Plane, Station Point, Horizon, VP, and Ground Line Station Point Picture Plane Ground Line Horizon VP One-Point Perspective

8. 2. Place plan and front views Station Point [camera] [image] Plane Ground Line Horizon VP 3. Sketch front face

9. 4. From front face, draw lines to VP Station Point Picture Plane Ground Line Horizon VP

10. 6. Draw side face Station Point Picture Plane Ground Line Horizon VP 5. Project back to picture plane

11. 6. Draw top face Station Point Picture Plane Ground Line Horizon VP

12. Place the Plan View Set Station Point (SP) Two-Point Perspective

13. The location of horizon and ground lines are infinitely variable. The location of the Horizon Line will depend on whether you want to view the object from above eye level or below eye level. The location of the Ground Line in relation to the Horizon Line will determine how far above or below eye level the object will be viewed. (Eye Line)

14. From SP, draw two // lines, intersecting at Picture plane Create LVP & RVP Project height to vertical line Place Side Elevation on Ground Line

15. Project width to Picture Plane; Draw vertical lines Draw lines to LVP & RVP
