In-Depth Information
elevation are quite subtle. To make the
peaks and valleys stand out a bit more, the
elevations are exaggerated while the
horizontal distances are kept the same.
The result is a profile that appears to have
higher high points, lower low points, and
steeper slopes in between. This makes the
terrain easier to visualize and analyze in
profile view. For example, with a vertical
exaggeration of 5:1, the height of peaks
and the depth of valleys appear five times
larger than the horizontal measurements.
Editing in Profile View
Once you have the Profile View panel open, you
can edit the design profile (also called a
vertical
alignment
) in a number of ways. One way is to
click and drag a triangular PVI symbol to a new
location. This is a powerful method for
establishing the relationship between existing
ground and proposed elevations (see
Figure
2-32
).
