7. Draw a line from the bottom of the lowest step tread 8 ″ (204 mm)
downward and then a few feet directly to the left.
Fillet the bottom-left corner of the stringer with a radius of 0, as
shown in Figure 10.28.
8. The last parts of the stairway to draw are the 2 ″ (51 mm) railing posts
and the handrail.
Move the angled line at the top of the stairs up 3 ′ -6 ″ (1067 mm) and
then offset it upward 2 ″ (51 mm).
9. Extend the upper line until it intersects the post on the left and the last
remaining vertical line dropped from the floor plan. Extend the lower
line only to the post on the left, as shown in Figure 10.29.
10. Draw a line from the right endpoint of the upper railing line perpen-
dicular to the lower line, and then fillet the corner. Erase the vertical
line that extends from the floor plan (see Figure 10.29).
