This command can be used to simultaneously create elevation labels
on a group or groups of contour polylines at elevation. To place the
labels, pick two points crossing the contour polylines at the desired
label location. The program will find all the contour polylines
that intersect the picked line (defined by the two picked points) and
will
place labels at the
intersection point of each contour. A second crossing line can be
initiated immediately, so multiple areas can be quickly
labeled while remaining in the command. The actual "z" elevation
of the contour line determines the label value.
Contour Label Options Dialog
Label Layer specifies layer name for the contour
labels that will be created.
Label Style: specifies the text
style to be used for labels.
Horizontal Scale is used in
conjunction with the Text Size Scaler to determine unit height of the
contour labels.
Text Size Scaler is a
scaler that will be multiplied by the horizontal
scale to set the actual text height
of the labels in AutoCAD units.
Decimals sets the decimal
precision for the labels to be
created.
Label Position determines the label position in relation
to the contour polyline.
Ignore Zero Elevation Polylines enables
the routine to filter out all entities with an elevation of
zero.
Hide Drawing Under Labels activates a text wipeout feature
that will create the
appearance of trimmed segments at the contour label, even though the
contour line is still fully intact. This feature provides the
user with the
best of both worlds; you have clean looking contour labels, yet the
contour lines themselves remain contiguous. This feature will
also hide other entities that are in the immediate vicinity of the
contour label.
When Align Text with Contour is checked, contour elevation labels will be rotated to align with their respective contour lines.
When Break Contours at Label is checked, the contour lines
will
be
broken and trimmed at the label
location for
label visibility.
When
Draw Broken Segments is checked, segments of contours that are
broken out for label
visibility will be redrawn as independent segments.
Specify the layer for these broken segments in the box to the right of
this toggle.
Label By Distance places the labels by distance
along the contour. The user is not prompted for screen picks of
contour crossing when this option is used.
When Draw Box Around Text is checked, a rectangle will be
drawn
around the elevation
labels.
Lable Index Only: When
checked, only Index contours are labeled.
Contour Label Options Dialog Opens Select the desired options and
press OK.
Define a line which slices the contours at the desired label
locations.
Pick 1st point: pick a point
Pick 2nd point: pick a point
By selecting two points the contour lines that cross the line
defined
by the two points are labeled.
