Editing Survey Figures
Mistakes in the field can lead to errors in the way linework is drawn. Once
again, the changes need to be made a certain way because you're dealing with
special survey objects, this time survey figures. Survey figures are linked to the
survey database but unlike survey points, they can be edited without accessing
the survey database. If you edit survey figures in this way, you need to be aware
that the objects you've edited are no longer in sync with the survey database.
When this occurs you should take steps to keep them in sync to ensure that the
correct data is used in the future.
Exercise 3.8: Edit Survey Figures
In this exercise, you'll edit several survey figures to correct errors that took
place due to incorrect translation from the field to the drawing.
If you haven't already done so, go to the topic's web page at
www.sybex.com/
go/civil3d2015essentials
and download the files for Chapter 3. Unzip the files
to the correct location on your hard drive according to the instructions in the
introduction. Then, follow these steps:
The
Essentials 5
database is the result of
correctly completing the
previous exercise. This
database is provided to
ensure that you start
the current exercise
with the correct version.
1.
Open the drawing named
Edit Survey Figures.dwg
located in the
Chapter 03
class data folder.
▶
2.
If the contents beneath the
Essentials 5
survey database are not
visible, right-click
Essentials 5
and select Open For Edit.
3.
In the top-right viewport, locate the building that is missing its
north side. Click the building figure line, and then click Survey
Figure Properties on the ribbon. Notice that point 285 is missing a
CLS (close) code that would provide the north side of the building
by closing the rectangle.
▶
4.
Click point 285 in the point list; then set the Closed value to Yes, and
click OK. The shape of the building is now closed. Because you used
the Survey Figure Properties command to edit this figure, the draw-
ing and the survey database are in sync.
At this point, you
could back out and fix
the point description.
However, for the pur-
poses of this exercise,
you'll edit the figure
instead.
5.
Press Esc to clear the previous selection. Pan to the southeast until
you can see the building to the west of the 6″ (150mm) pine. This
building should appear as two separate buildings.
6.
Click the building figure, and then click Survey Figure Properties on
the ribbon.
