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.

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 CAD session
unless it is reset using the 'GT_ShowDlg' command.

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.

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

Add / Remove redundant closing (last) vertex from polylines.
Command
line : GT_FIXCLOSED
The GT_FIXCLOSED command helps to add or
remove the last vertex of a closed polyline. In other words, this command adds
or removes the redundant duplication of the last vertex in closed polylines.
Add Closing Vertex
Adds a redundant "last" vertex to closed polylines. This duplicates
the first and last vertex of a closed polyline. The new vertex is added only if
the distance between the first and last vertex is greater than the closing
tolerance specified in the dialog box above.
Remove Closing Vertex
Removes the last vertex from the polyline if the distance between the first and
last vertex is less than the value specified in the dialog box above.

Enhanced fillet command
Command
line : GT_FILLETPOLY
The GT_FILLETPOLY command
allows filleting to be done between two polylines. The two segments of the
polyline nearest to the ends picked will be filletted according to the specified
radius.
The command is now offered as a replacement for the standard fillet
command, which has several short-comings. For example, the AutoCAD/Bricscad fillet
command does not work correctly under the following situations:
a. Fillet between an ARC and a polyline object
b. Fillet between a LINE and polyline that has arc segments near the fillet end.
c. Fillet between an ARC and polyline that has arc segments near the fillet end.
The GT_FILLETPOLY command
processes all of the cases in (a), (b) and (c) above successfully.
Fillet Radius: Specify the radius to be applied for filleting across all the
segments of the multiple selected polylines.
 Command: filletpoly
Select first polyline: <do so>
