Specify a new start point for polylines
Command
line : GT_NEWSTART
The GT_NEWSTART
command allows to specify a new start point for closed polylines. Use this to
change the start point of closed polylines without changing the polyline
geometry. The new point specified must fall on the polyline and the nearest
vertex is taken as the start point and the polyline is re-constructed.

Explode wide polylines retain width geometry
Command
line : GT_XP_WPL
The GT_XP_WPL command allows Linear polylines with
widths to be exploded and to retain the geometry of the original polyline. The
exploded objects will be created as lines.

Filter polylines
Command
line :
GT_PLFILTER
Filters polylines based on their properties.

The following properties of polylines can be filtered from the selection set.
| 2D |

Open |
| Closed |
Fitted |
Arced |
| Splined |
Meshed |
Polyface |
| Z value |
Length |
Number of vertices |
| Area |
Start-End Distance |
|
The length, area, number of
vertices or start-end distances are specified by entering < n, <= n, >
n, >= n, = n, /= n where "n" is the value to check for.
Specify the numeric logical
comparative operator in one of these ways.
< 'Value' - Less than
'Value'
<= 'Value' - Less than or equal to 'Value'
> 'Value' - Greater than 'Value'
>= 'Value' - Greater than or equal to 'Value'
= 'Value' - Equal to 'Value'
/= 'Value' - Not Equal to 'Value'
Enter Length / Area / Z criteria: <= 55.0
This would select all objects with the specified property less than or equal to
55.0
Notes: The Start-End distances are always measured in slope in the case of 3d
polylines. The Z value check will fail if there is even one vertex in the
polyline that fails to meet the criterion.

Offset 3D polylines
Command
line : GT_3DOFFSET
The GT_3DOFFSET command is used to offset 3d
polylines in the same manner as 2d polylines. 3D polyline can be offset both
horizontally and vertically. This can be a very useful in several civil
engineering design situations that require the offsetted polyline to be elevated
or lowered by a fixed amount relative to the source polyline.

Reshape part of a polyline
Command
line : GT_PARTRESHAPE
The GT_PARTRESHAPE command can be used to re-shape or, in other words, re-digitize part of a
polyline. You will be asked to pick two points on a polyline and will be prompted to pick the new locations of the points in between. The source polyline will then be updated and the
newly digitized points will be used instead of the old set of points between the two source points.

Provide detailed polyline statistics
Command
line : GT_PL_STAT
Create output file:
Check this option if you want the output from this command to be saved to
an ASCII text file.
Browse: Click on this button to select an output file to save the
polyline statistics listing
Create tabular output: Creates the polyline statistics in a tabulated
form
Treat polyline as elevation view: Checking this option causes the
polyline to be treated as elevation view. In other words, the X and Y of the two
vertices of the polyline are treated as measurements in the Z plane and the
difference between the Y values is taken as the actual elevation difference
between the points.
Hide dialog box and run GT_PL_STAT with current settings next time:
Checking this option causes GT_PL_STAT to run the next time without dialog
box. You will be prompted to only select the polyline to compute statistics and
the program operates with the current settings as last set. This setting enables
users to run the command quickly without having to navigate through the dialog
box each time. The setting remains in place for the current AutoCAD session
unless it is reset using the 'GT_ShowDlg' command.
Table Text Height: Specify the required text height for the contents of
table.

Explode splined and fitted polylines
Command
line :
GT_XPSPL
This command is used to explode splined and fitted
polylines. Upon selecting the splined or fitted polylines, they are exploded
into their line or arc segment and then joined back to produce a
"plain" polyline with line or arc segments. This command is useful to
many geographic and surveying users who require a non-splined non-fitted
polyline for many design purposes.

Convert a spline/ellipse to a polyline
Command
line :
GT_SPL2PL
It is possible
to use the GT_SPL2PL command to convert splines to polylines in three different
ways.
Join Fit points: This option joins all the Fit points (DXF Code
11) of a spline and creates a polyline out of it.
Join Control points: This option joins all the Control (DXF
Code 10) points of a spline and creates a polyline out of it.
Re-create spline geometry (DXF method): This method is the most
precise and attempts to re-create the geometry of the spline as closely as
possible. It works by creating the DXF output of the spline object in Release 12
format and then imports it in again as a polyline. With long polylines, this
may occasionally cause AutoCAD to become unstable and even crash. Please ensure
that you save your drawing prior to running this command.
Interpolate by inter-vertex distance: This method allows
specifying a distance between the two vertices of the polyline that will be
created.
Vertex distance: Specify
the vertex distance here. Every polyline vertex will be spaced apart by this
amount.

Express PEDIT
Command
line :
GT_XV
Express Pedit allows a faster
and quicker way to access some of the Pedit Edit Vertex commands like Move,
Insert and Break. Additionally, it also provides extra commands like polyline
statistics - slope length, horizontal projected length, X, Y and Z coordinate
extents and number of vertices.
Select vertex on polyline:
Next / Previous / Move / Z / Insert / Break / Statistics / Settings / eXit
<Next>:
Use Next and Previous to navigate through the
vertices of the polyline. The current vertex is always shown with a cross
attached to it.
Move allows specifying a new location for the current vertex.
Z allows the elevation of the current point to be set
Insert allows a new vertex to be added between the current vertex
and the next vertex.
Break allows the polyline to be broken at the current point. Saves
some keystrokes as compared to the Pedit command.
Statistics: Generates detailed polyline statistics
Settings allows specifying whether the Move and Insert
sub-commands take the Z value from the new location or inherit it from the
current vertex elevation.
An example of the statistical information is shown below:
Slope length:22719.1175 Projected horizontal
length:22718.4936
Max. X-coordinate:2025286.6092 Min. X-coordinate:2010210.0148
Max. Y-coordinate:924910.0082 Min. Y-coordinate:913590.4827
Max. Z-coordinate:212.5000 Min. Z-coordinate:45.6000
Number of vertices:15
Press any key to continue.
Tech Info: Make sure that the entire polyline is visible on
screen.
