Draw Spot Elevations
This command creates spot elevation labels based on user
settings. ![](dialog1.bmp)
Label Style: This option at the top of
the dialog determines which options are available in the rest of
the dialog.
Label with Leader: This
option draws a leader between the spot location and the label. The
style of the leader is controlled by the current DIMSTYLE
settings.
Label with Symbol: Draws
the specified symbol at the spot with the label off to the
side.
Carlson Point: This option
creates a Carlson point entity with the point#, elevation,
description attribute block and stores the point to the current
coordinate file. When creating Carlson points, there is an option
for Prompt For Description for entering descriptions for the
points for the point entities and coordinate file.
Label Decimal on Point:
Draws only the elevation label and positions the label so that the
label decimal is on the spot.
Label Insertion on Point:
Draws only the elevation label and uses the spot location for the
insertion point of the label.
Label Only: Draws the label without any indicator of the
exact reference point for the label.
Symbol: Specify the symbol
to be used for the location of the spot elevation. If Draw with
Leader is selected, the use of a symbol is automatically disabled.
Along with the symbol name, you can also set the Size Scaler to size the symbol and the
Offset Scaler to control
the offset between the symbol and the label. The Prompt For Symbol Angle option allows
you to rotate the symbol. Otherwise, the symbol is drawn horizontal
to the current twist screen.
Leader Segments controls
how many leader segments the program will prompt for. Place Label Along Leader draws the
label along the leader instead of horizontal off the end of the
leader. Leader Horizontal
Tick draws a short horizontal segment at the label end of
the leader. Arrow Scaler
controls the size of the arrowhead.
Draw Point Node: Specify whether to create a node (point
entity) at the spot.Options: Under Options, there are
settings to control the layer, text style, text size and
prefix/suffix for the labels. Box
Labels controls whether to draw a box around the label and
Box Scaler controls the
size of the box. Locate Label On
Real Z sets whether the label and symbol are placed at the
spot elevation or at zero elevation. There are several settings for
fields to prompt for when placing each spot label including prefix,
suffix, position and angle.
Use Attribute Block: This option uses a block with
attributes to draw the spot elevations. This allows you more
control of the label layout. There is one default spot elevation
attribute block called spot_z1.dwg in the Carlson Support folder.
To customize the layout, open the attribute block drawing, make
your edits and then save the drawing. The attribute block uses
three attribute definitions: Integers, Decimals, Suffix. Integers
is for the elevation digits to the left of the decimal point.
Decimals is for the digits to the right of the decimal point.
Suffix is a text description.
Placement Method:
Individual: Prompts the user for a screen pick or a point
number to specify the location of the spot elevation.
Pick Entity: This method labels the elevation of the
selected 3D entity. For 3D polylines, the elevation comes from the
polyline at the location the polyline is selected.
Point Range/Group: Draw spot elevations at the specified
point numbers or point group name from the current coordinate
file.
Interval: Prompts the user to select an existing polyline
and specify an interval distance to set spot labels along the
polyline. It also prompts for number and interval for additional
labels to be set at offset distances right and/or left of the
polyline.
Use Reference:
Off: User is prompted to supply elevation for each new spot
elevation.
Single Surface File: Prompts user to specify the
triangulation or grid surface model file to read the elevations
from. Spot elevations created with this method are automatically
updated if the surface model elevation changes.
Two Surface Difference: Prompts user to specify an existing
surface file and a design surface file, and labels the elevation
difference between the two.
Slope Percent/Ratio From Point/Polyline: These methods allow
you to set the spot elevation by a slope percent or ratio from a
reference point/polyline. These methods have another option for
whether to Prompt for Slope
which will prompt for the slope from the reference for each spot.
Otherwise, the Slope From
Reference setting in the dialog is used. When using the
Polyline reference method, the program finds the station-offset of
the spot point along the polyline and uses the elevation of the
polyline at that station for the reference.
Link To Reference applies
to using a surface file or 3D polyline for the spot elevations.
This link option will automatically update the labels when the
reference surface file or 3D polyline change.
The Hide Drawing Under Labels option creates a wipeout under
the spot label to hide any other drawing entities behind the
label.
The Integers setting
controls how many decimal places to the left of the decimal point
to label and the Decimals
settings controls how many decimal places to the right of the
decimal point to label.
Prompt for Prefix/Suffix:
These options will prompt for the labels for each point which is
useful when labeling different kinds of spots.
Prompt for Label Position:
When using Label With Symbol style, this option will prompt for
where to place the label for each spot.
Prompt for Elevation:
Prompts to enter the elevation for each spot. Otherwise, the
elevation of the picked point is used.
Prompt for Label Angle:
This option allows you to rotate the label for each spot.
Otherwise, the label is drawn horizontal to the current twist
screen.
Vertical Offset adjusts the
elevation label by the specified amount.
Additional Label has
separate settings for Vertical
Offset, Prefix and
Suffix which allows for
labeling two elevations for the same spot such as labeling both
bottom and top of curb.

The
Save and
Load buttons write and recall the settings
to a .LSE file so that you can store different label styles and
share them.
