Setting up Lines for the Heights
The line you offset establishes a baseline to represent the ground or the bottom
of the cabin. You can now offset the other height lines from the baseline or from
other height lines:
1. Check the status bar to make sure that Polar Tracking, Object Snap,
and Dynamic Input are in their on positions while the other buttons
are off. The Endpoint osnap should be running.
2. Change the layer of the offset line from A-WALL to A-ELEV-WALL,
and perform the following offsets:
6 -7 (2007 mm) up to mark the lowest
edge of the roof supports and the bottom edge of the soffit.
Offset the base line
Offset the same line
6 -11 ¼ (2115 mm) and again 7 -0 (2134
mm) to establish the lower and upper heights of the roof cover-
ing respectively.
Finally, offset the base line up 17
-0 (5182 mm) to mark the
ridgeline of the roof.
The lines should look like those shown in Figure 10.4.
a soffit is the under-
side of the roof over-
hang that extends
from the outside
edge of the roof
back to the wall.

3. Offset the base line 2 -11 (889 mm) to represent the bottom of the win-
dows, and then offset the offset line 3 -6 (1069 mm) to mark the top.
