STAIRS
Drawing stairs inperspective is easiest
when we can determine the vanishing point
for the inclined li nes that connect the stair
nosings.
We first lay out the perspective view of the
horizontal stair run on the floor plane.
We arenot concerned yet with the
individual treads of the sta irway.
----. We then extend a vertica l plane tothe
height of the stair landing or next floor
level.
· - .. Next we divide one side of this plane into
the number of equal risers in the stair run.
• We can determine the height of the first
riser in perspective.
We draw an incline line from the topof
d
the first riser to the top of the landing or
upper floor level.
----:-r-----;.?L---+-~--. This inclined line is subdivided by extending
horizontal lines from the riser markings.
• From these points, we draw the risers and
treads as vertical and horizontal planes in
perspective.
We can use the vanishing points for
inclined lines todraw other elements
parallel to theinclined lines, such as stair
stringers and railings.
