Types of Perspective Drawings Three-point is used for tall structures with many levels Two-point is used to present the exterior of a structure, but can be used for interior designs One-point is used to show interior layout or exterior views

Perspective Terms Ground line (G.L.) represents the horizontal surface at the base of the perspective drawing Used to make vertical measurements

Perspective Terms Station point (S.P.) is the position of the observer’s eye Where all width measurements converge As the S.P. moves closer to picture plane the width will become smaller Placed so the structure will be in a 30° cone

Perspective Terms

Perspective Terms Horizon line (H.L.) drawn parallel to the ground line and represents the intersection between the ground and sky Usually placed between 5’ and 6’ above the ground line A high H.L. will appear as if you were looking down on the structure

Perspective Terms Vanishing points (V.P.) are placed on the horizon line Placement of V.P. for a two-point perspective will be determined by the station point and angle of the floor plan All lines are drawn to the V.P. One or two V.P. are given

Perspective Terms

Perspective Terms Picture plane (P.P.) is the plane that the view of the object is projected onto Represented by a horizontal line Parts above the P.P. will appear smaller and those below will appear larger A surface rotated away from the P.P. will become foreshortened in the perspective view

Perspective Terms True-height line (T.H.L.) is a line projected from a point on the picture plane to establish true height After being projected to the T.H.L. the line is projected to the V.P. Experimenting with various line placements a variety of effects can be created

Perspective Terms

Two-Point Perspective Begin by printing a floor plan and an elevation Use paper about 4’ long and 2’ high Use colored pencils to assist in distinguishing lines

Two-Point Perspective Draw picture plane Tape floor plan at 30° to picture plane with one corner on that line Draw cantilevers and roof outline on floor plan Establish ground line greater than the height of the structure

Two-Point Perspective Tape elevation to the side of the drawing so ground lines are aligned Establish true-height line Establish station point Establish horizon line Establish vanishing points

Two-Point Perspective Project lines from roof corners down to the station point, but stop line at picture plane Project these down from picture plane to drawing area Project height of roof onto true-height line Project roof heights to vanishing points Complete roof layout

Two-Point Perspective Project lines from each wall corner to station point stopping at the picture plane Project these down from the picture plane to the drawing area Plot outline of all windows and doors in a different color

One-Point Perspective Draw picture plane Tape floor plan at a larger scale to picture plane Locate station point Establish ground line which will be the floor Establish ceiling heights up from floor

One-Point Perspective Establish width of the drawing Establish the vanishing point Project corners to the vanishing point from the elevation Project corners to the station point from the plan view Lay out walls, floor, and ceiling

One-Point Perspective Measure cabinet height on elevations and project these to the true-height line Lay out the shape of the base cabinets Lay out the cabinets on the back wall Lay out upper cabinets

One-Point Perspective Lay out cabinet widths and appliances from station points onto the drawing Block out windows and doors Block out soffits, skylights, and other ceiling items
