FiGuRE 16.84 The cabin model with the roof and extended walls
displayed
tweaking the Roof and Walls
As you can see, the walls poke through the roof on the south side of the cabin
and you still need to modify the roof so that it only projects out over the pop-
out. You'll do these tasks using the subobject grips and Boolean tools.
1. Use the ViewCube to rotate the view so that you can see the roof that
covers the pop-out.
2. Make sure Dynamic UCS is turned on and Endpoint osnaps are run-
ning; then start the BOX command.
3. Create a box, starting at the southeast corner of the roof with a foot-
print that is 3 ′ -4 ″ wide and extends to a point 1 ′ -6 ″ (457 mm) from
the pop-out.
Give the box some height and then repeat the process on the oppo-
site side of the pop-out, as shown in Figure 16.85. The Dynamic UCS
tool creates the boxes aligned to the roof.
4. Use the grips to extend the outside edges of the boxes beyond the
edges of the roof (see Figure 16.86).
