1. Set Picture Plane, Station Point, Horizon, VP, and Ground Line One-Point Perspective Picture Plane Horizon VP Ground Line Station Point
2. Place plan and front views [image] Plane Horizon VP Ground Line 3. Sketch front face Station Point [camera]
4. From front face, draw lines to VP Picture Plane Horizon VP Ground Line Station Point
5. Project back to picture plane Picture Plane Horizon VP Ground Line 6. Draw side face Station Point
Picture Plane Horizon VP Ground Line Station Point 6. Draw top face
Two-Point Perspective Place the Plan View Set Station Point (SP)
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.
From SP, draw two // lines, intersecting at Picture plane Create LVP & RVP Place Side Elevation on Ground Line Project height to vertical line
Draw lines to LVP & RVP Project width to Picture Plane; Draw vertical lines
