polyline vertices
Command line : GT_VXLABEL
This command places text labels along polyline, line,
3dfaces and spline vertices. The following types of labels can be created for
each vertex.
Annotate Using:
X co-ordinate value:
The X co-ordinate of each vertex is written as a text label next to each
vertex.
Y co-ordinate value:
The Y co-ordinate of each vertex is written as a text label next to each
vertex.
Elevations (Z):
The elevation of each vertex is written as a text next to each vertex.
XY co-ordinate value:
The x and y co-ordinates of each vertex is written as a text label next to
each vertex.
XYZ co-ordinate value:
The x, y and z co-ordinates of each vertex is written as a text label
next to each vertex.
Running Number:
The vertex count starting from the beginning is written (this initial
count can be set by the user)
Cumulative Slope Distance from start:
The cumulative slope distance from the first vertex is computed and
written next to each vertex (the initial starting distance can be set by the
user).
Cumulative Horizontal Distance from start:
The cumulative horizontal distance from the first vertex is computed and
written next to each vertex (the initial starting distance can be set by the
user).
Prefix Options:
Prefix with X=, Y=, Z= Choosing this option places the prefixes, X=,
Y=, Z= before each coordinate value
Prefix with E=, N=, H= Choosing this option places the prefixes, E=,
N=, H= before each coordinate value
No prefix (co-cordinates only) No prefixes are written, only
co-ordinates values are written
Prefix with M=, P=, H= Choosing this option places the prefixes, M=,
P=, H= before each coordinate value. This is Portuguese notation for
Easting and Northing.
Label first and last points only:
Places labels on the first and last points of polylines only. Useful if the
polyline is too dense and you do not want lables at every point.
Reset vertex numbering for every line/polyline:
Starts vertex numbering from the specified start value for every polyline or
line. If this option is not checked, vertex numbering continues incrementing
across each polyline.
Apply elevation check before labeling.
Checking this box makes a check for the elevation between specified range
and labels only those vertices which fall between the range
From [elevation]
If Apply elevation check before labeling is chosen then the From
[elevation] box allows you to enter the start elevation for range check.
To [elevation]
If Apply elevation check before labeling is
chosen then the To [elevation] box allows you to enter the end
elevation for range check.
Starting Station Number:
If Running Number is chosen as the label option above, then this
option allows the first station number to be set. You may want to set this to
a number higher than 1 if this polyline is being labeled in succession to
another polyline which was preceding it.
Starting Station Distance:
If Cumulative Distance from start is chosen as the label option above,
then this option allows the first station distance to be set. You may want to
set this to a number higher than 0.0 if this polyline is being labeled in
succession to another polyline which was preceding it.
Label Text Height:
Specifies the label text height.
Rotation Angle:
Specifies the rotation angle for text.
Horizontal Text Offset from vertex:
Specifies the offset distance in the horizontal (X) direction in CAD units
from the vertex position at which you want the label to appear.
Vertical Text Offset from vertex:
Specifies the offset distance in the vertical (Y) direction in CAD units from
the vertex position at which you want the label to appear.
Label-name: Displays the selected layer name.
Select: Pops-up the Select Label Layer
dialog box for choosing the required layer.

polylines with attached data
Command line : GT_PL_DATALBL
The GT_PL_DATALBL command is used to label polylines with
attached data – like object data, extended entity data or database-linked
data. When multiple object labeling is chosen, the label is automatically
placed at the mid-point of each object. When single object labeling is
chosen, the user has to specify the label locations. You can create complex
label strings by joining data from multiple fields with a specified
delimiter, with prefix/suffix etc as required.
The command offers several sub-dialogs which allow individual categorized
parameters (OD / DB / XD) and general settings to be specified.
Annotation parameters:
The annotation parameters specify the visual appearance of the annotation and
are common to all the three data types being annotated.
Style: This button brings up the annotation style dialog box that
determines how the text label annotation is to be placed relative to the
polyline and view direction

polyline segments
Command line : GT_SEGLABEL
This command
writes the segment distance annotation along each segment of the
polyline.
What to label?
Distances: Choosing this option places the inter-vertex distance
as the label text.
Bearing: Choosing this option places the surveyor’s bearing between two
vertices as the label text.
Slope: Choosing this option places the segment slope annotation as the
label text.
Distances@Slope: Choosing this option creates the annotation in the
format - ‘Distance @ Slope'
Distances@Bearing: Choosing this option creates the annotation in the
format 'Distance @ Bearing'
Running Number: Choosing this option allows to label the segments as sequential numbers
Labelling Formats:
Distances: Clicking this option opens up a distances format dialog box. This allows
the distances to be annotated in various ways.
Slope: Displays distances as actual slope distances.
Horizontal: Displays distances as horizontally projected values.
Apply Segment length check before labeling: Checks the length of the
segment and if it falls within the specified range only, they will be labelled.
Bearing: Clicking this option opens up a bearing format dialog box. This allows
the bearings to be annotated in various ways.
Decimal Degrees: Writes the whole circle bearing in decimal degrees.
Deg/Min/Sec (000-00-00): Writes the bearing in degrees, minutes and
seconds in the DDD-MM-SS format.
0d00'00': Writes the whole circle bearing in deg, min and sec format.
N 0d00'00' E: Writes the bearing in surveyors units.
Radians: (0.000r) Writes the whole circle bearing in radians
Gradients: (0.000g) Writes the whole circle bearing in gradients (One
gradient=1/400th of a circle)
Slope: Clicking this option, opens
up a slope format dialog box. This allows the slopes to be annotated in
various ways
As percentage: Choosing this option causes the grade annotation to be
created as a percentage. For example, uphill grades are created as "2%
Up" and downhill grades are created as "2% Down".
As decimal: Choosing this option causes the grade
annotation to be created in decimal format. For example, uphill grade will be
created as "1:50 Up" and downhill grade will be created as "1:50
Down".
Direction: Choosing this option causes the strings
"Up" or "Down" to be written along the segment depending
on whether the slope is going downward or upward.
Arrow in Elevation Direction [Up->Down]: Choosing this
option draws an arrow along the segment in Upward to Downward direction with
respect to the elevation.
Arrow in Elevation Direction
[Down->Up]: Choosing this option draws an arrow along the segment in Downward to
Upward direction with respect to the elevation.
Degrees: Choosing this option causes the slope values in
degrees to be annotated next to the segment.
Per Mille: mean 'Per 1000' : This slope annotation method is often used in hydraulics to denote the slopes of canal beds and similar structures. It is
denoted as 'x o/oo', where 'x' is the amount of slope per 1000 of horizontal distance.
Precision for grade value: Enter the number of decimal places to be used
in the precision for grade values.
Treat polyline as elevation value: If this option is checked, the
polyline is treated as an elevation view (or long/cross section as called in
some countries) and the segment slope annotation is done accordingly. In
elevation view, the polyline is assumed to be drawn in the Z plane.
Vertical exaggeration factor: This is the factor by which the Z value of the polyline vertices must be multiplied when the polyline is being viewed
in 'ElevationView'.
Annotation Position:
Along Segment: Choosing this option places the annotation text along
the direction of the segment.
Perpendicular to segment: Choosing this option places the annotation
text perpendicular to the direction of the segment being annotated.
The next two options further specify the annotation text placement positions
by specifying if the annotation is along the segment, above or below it. For Perpendicular
to segment option above, The Above, Below and On Segment
option in this section will be grayed out.
Above Segment: The annotation will be placed above the segment. For
the purpose of determining the position of anotation, the segment is imagined
from its start point to end point as a horizontal X-axis, and the the space
above it is considered as the Space Above and vice versa.
Below Segment: The annotation will be placed below the segment. For
the purpose of of determining the position of anotation, the segment is imagined
from it start point to end point as a horizontal X-axis, and the space below
it is considered as the Space Below and vice versa.
On Segment: The annotation will be placed on and along the segment.
Left of segment: This option enables the annotation to be placed to
the left of the direction of the segment being annotated. This is applicable
only when the Perpendicular option is chosen.
Right of segment: This option enables the annotation to be placed to
the right of the direction of the segment being annotated. This is applicable
only when the Perpendicular option is chosen.
Text Orientation:
Always upright: Flips text by 180 degrees to make them readable.
Always aligned: Does not perform any text flipping. The rotation angle
will be as determined, entirely by the segment direction.
ARC label options:
Midpoint of arc: Choosing this option places the label at the midpoint
of each arc segment. This may be an arc segment of a polyline or an ARC
object.
Midpoint of chord: Choosing this option places the label at the
midpoint of each chord length of the arc segment. This may be an arc segment
of a polyline or an ARC object.
Label Formatting:
Label Text Height: Specifies the label text height.

contour polylines
Command line : GT_CONTLABEL
The
GT_CONTLABEL command places labels along polylines, lines, arcs and splines.
You can use it to label just about anything that is a linear object such as
label roads, fences, boundaries, traversas, etc. The label can be the
elevation of the object or you can specify a user string to be placed as a
label.
What to label?
Elevation: Check this option to label the elevation information of the polyline
User String: Check this option to enter a user-defined string value
that is used to annotate along the polyline.
Curve Length: Check this option to label the length of contour.
Text Orientation
Always upright: Check this option to create labels that are always face up. This cause
any text that is between rotation angles of 90 and 270 degrees to be flipped
by 180 degrees.
Always aligned: Check this option to create labels which are always
aligned to the direction of the line. This can result in inverted text.
Text spacing
Repeated: Checking this option causes GT_CONTLABEL to place the labels repeatedly
along the line at an interval specified in Annotation Distance (see below)
At picked point: Checking this option allows the user to manually pick
points on the line where the annotation is desired. This option does not
place annotations automatically and does so only at the picked point.
At cutting line locations: Checking this option allows the user to
specify two points that define a line and the program will generate
annotations at every intersection of the line with the selected contour
polyline objects.
At mid-point of curve: Checking this option places the label at the
mid of the contour.
At ends of the curve: Checking this
option to place the label at the two ends of the contour.
Other annotation parameters
Text Style: Select the text style to use for the annotation.
Text Height: Specify the text
height to use for annotation.
Annotation Spacing: Specify the annotation
distance between labels when the Repeated Option above is chosen.
Annotation Label String: Specify the text label to be used if the User
String option above is chosen.
Label Layer: Displays the selected layer name.
Select: Pops-up the Select Label Layer dialog box
for choosing the required layer.
Color: Pops-up the Standard color dialog box for color
selection.
Break Contour object around label: If this option is checked, the contour object will be broken around the
text label.
Label at midpoint of contour if length is less than spacing: Checking
this option causes only one annotation of text at the midpoint of the contour
if its length is less than the label spacing.

points, based on layer names
Command line : GT_ANNOTPOINTS
The GT_ANNOTPOINTS
command is used to annotate a set of points based on a layer lookup table.
This command is useful in several surveying applications where the raw data
is first imported into AutoCAD / Bricscad as a set of random point objects placed on
several different layers. It is then often required to label these points
with meaningful and descriptive text labels with correct text style and
height. This command helps to create such a labeled text. Each set of
annotation parameters (like text label, style, height etc) is specified on a
per-layer basis. These sets of per-layer annotation parameters can be
saved/restored from ASCII files.

Create
/ Update length annotation
Command line : GT_LENTEXT
The GT_LENTEXT command creates a length annotation. If you have a segment of a line or polyline, its length can be easily annotated as text using this command.
Often, the drawing units are scaled and different from the real units. To accommodate this, it is possible to scale the length using a length modifier. You can add, subtract, multiply or divide the DWG length by a factor to create the exact annotation desired.
