FIGURE 6.24
The studio unit
so far
With Polar Tracking set to 45° and Osnap Tracking turned on in a crowded drawing, you may
find that you're selecting points you don't really want to select. Just remember that if a drawing
becomes too crowded, you can turn off these options temporarily by clicking the Object Snap
Tracking or Polar Tracking button in the status bar.
In this exercise, you used Polar Tracking and Ortho mode to position the two lines used for
the exterior walls of the studio unit accurately. This shows how you can take advantage of exist-
ing geometry with a combination of tools in the status bar.
Now you'll finish the balcony by adding a sliding-glass door and a rail. This time, you'll
use lines for construction as well as for parts of the drawing. First, you'll add the door jamb by
drawing a construction line. A
construction line
is a line that has an infinite length, but unlike a
ray, it extends in both directions. After drawing the construction line, you'll use it to position the
door jambs quickly.
Follow these steps:

Zoom in to the balcony area, which is the smaller rectangle at the bottom of the drawing.
Click the arrow from the Tool Sets palette to expand the Open Shapes panel and then
select the Construction Line tool. You can also choose Draw
Construction Line from
the menu bar, or enter
