Place Labels
This feature allows you to place the appropriate elevation labels
at selected locations on C&G contour polylines. The label
is a TEXT entity overlaying
a WIPEOUT entity. The
WIPEOUT entity serves to
create a space between the label text and the contour line and to
keep the contour line from showing through the text and obscuring
it.
If you have not already done so, please review the contour labeling
settings by choosing the CG-Survey
> Topo > Topographic Settings menu item
The labels will be created on the Main and Intermediate Contour Label
Layers. The Labeling
Interval determines which contours are labeled. For
example, if the Labeling
Interval is set to 2.00, then every C&G contour polyline
that you choose having an elevation evenly divisible by 2.00 will
be labeled. The Label-Contour Separation Distance:. is
the space separating the contour line and the start and end of the
label text.
Once you have verified the correct settings, choose the
Label Contours > Place
Label menu item.
At the prompt (see below) use the left mouse button to pick any
point that is on one side of the contour line you wish to
label.
Pass a line thru the contours to
be labeled.
Pick first point on line.
[<ENTER> to quit]:
Now, at the next prompt (see below), drag the rubber band line
through one or more of the contours you wish to label and click the
left mouse button a second time.
Pick second point [<ENTER>
to quit]:
The labeling operation can be repeated as many times as needed,
then press Enter to end the command.
Some Trouble Shooting Tips for Labeling Contours:
When a C&G surface is opened it is shown only as a graphic
image overlying the drawing. Therefore, before you can place
labels on the contour lines, the surface must be written to the
drawing using the CG-Survey >
Topo > Write Surface to DWG menu item..
If the labels do not appear on the contour lines you chose, verify
the elevation on the contour using the CAD LIST command.
Also, try changing the Labeling
Interval setting on the Topography tab of the C&G Options dialog.
If the labels still do not appear on the contour lines, look at
Drawing Settings tab of the
C&G Options dialog and
verify that the Text Size
is set to a value that is large enough to be seen when viewing the
contours.
If the elevation labels are created with an incorrect number of
decimal places, check the Elevation Precision on the Rounding tab of the C&G Options dialog under
Text in Drawing. Use
the CAD UNDO command to
undo the previously placed labels and try again.
