2. In the view you just created, open the Properties palette and check the boxes for Crop
View and Crop View Visible. This will turn on the crop region around the point
cloud. We're looking to isolate the Keeper's Quarters, so drag in the edges of
the point cloud until you can isolate the house on the left of the tower (Figure 21.13).

3. From the site visit and what we can see in the point cloud, we know the lighthouse and
keeper's quarters are solid brick in structure. The keeper's quarters is a one-story brick
building with a plaster finish coat on the interior. The building is historic and won't fit
within the context of modern construction practices, so we'll need to do a bit of mea-
suring. Zooming in on the upper-right corner of the view, we can use the Measure tool
(located in the Modify tab of the ribbon) to figure out the average thickness of the wall
(Figure 21.14). Based on taking some sample measurements, we're going to assume an
average width of 4 ½ʺ (115 mm).
