FiGuRE 10.29 Finishing the stair rail
11. To create the posts, draw a line from the midpoint of a stair tread
upward and then offset it 1 (25.5 mm) to the left and right. Erase
the original line and then trim or extend the other two lines until
they intersect with the lower railing line.
12. Using the top-right corner of each step as a reference point, copy the
post to the other three steps.
When you're done, your deck should look like Figure 10.30.
Drawing the Supports and Foundation
The cabin rests on a foundation, and the decks are supported by concrete posts.
You can quickly draw these with the RECTANG command using object snaps and
the Object Snap Tracking tool.
1. Using the Layer pull down, change the current layer to A-ELEV-FNDN
from the Home tab Layers panel.
2. Start the RECTANG command, and draw a rectangle with the first point
at the right end of the lowest horizontal deck line and the second
point 1 (305 mm) to the left and 2 -10 (864 mm) below (-1 ,-2 -10 )
or (-305,-864) that point.
3. Extend the lower stringer line until it intersects the support post, as
shown in Figure 10.31.
4. Zoom out so that you can see the entire cabin, and start the RECTANG
command again.
