The Polyline tools are a set of tools for performing various types of editing and inquiry operations on polylines.

Toolbar : Polyline Tool Set 2
      Menu : GeoTools Polyline Tool Set 2 Draw 2D/3D polylines with automatic edge panning.  
Command line : GT_AUTOPAN 
The GT_AUTOPAN command allows polylines to be drawn across the screen with the auto panning feature. This is a useful tool in many heads-up digitizing projects where the user needs to create long polylines that may often span across and beyond the limits of the current view.

Pan activation (percentage) of screen edge: Specify the screen edge width (in percentage) at which auto-pan should activate if the picked point of the polyline happens to be within it.

Pan displacement (percentage) of screen edge: Specify the amount (in percentage) that the view should scroll when auto pan activates.

Toolbar : Polyline Tool Set 2  
      Menu : GeoTools Polyline Tool Set 2 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.

      Menu : GeoTools Polyline Tool Set 2 Offset multiple polylines INwards or OUTwards. 
Command line : GT_INOUTOFFSET

The GT_INOUTOFFSET allows multiple closed polylines to be offsetted INwards or OUTwards with one single command.
Command: GT_INOUTOFFSET
Select Objects: (select polylines to offset)
Offset direction: [ Inwards/Outwards ] <Outwards>: (Type Inwards or Outwards)
Horizontal offset distance : <1.0000>: (Enter horizontal distance to offset)

Toolbar : Polyline Tool Set 2 `
      Menu : GeoTools Polyline Tool Set 2 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.  

Toolbar : Polyline Tool Set 2
      Menu : GeoTools Polyline Tool Set 2 Mark Intersection points along lines, polylines, arcs
Command line : GT_INTERSECT

The GT_INTERSECT command can be used to mark points of intersection between polylines, lines, arcs and/or splines. Please be aware that this command does not mark self-intersections between the segments of the same polyline or spline object. Instead, it marks points where each object intersects with other objects in the selection.

Toolbar : Polyline Tool Set 2
      Menu : GeoTools Polyline Tool Set 2 Mark junction points on a network of linear objects
Command line : GT_JUNCTION
The GT_JUNCTION command creates points at every junction node. A junction is defined as a point where at least three or more segments branch out in as many different directions.

Please note that while the GT_INTERSECT command creates points at every segmental intersection, the GT_JUNCTION command creates points at every junction or node where there is an explicit vertex or end point or ARC or LINE.

Toolbar : Polyline Tool Set 2
      Menu : GeoTools Polyline Tool Set 2 Determine direction of polyline
Command line : GT_PL_DIR 
The GT_PL_DIR command determines if the selected polyline vertices flow in the clockwise or counter clockwise direction

Toolbar : Polyline Tool Set 2
      Menu : GeoTools Polyline Tool Set 2 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 CAD session unless it is reset using the 'GT_ShowDlg' command. 

Table Text Height: Specify the required text height for the contents of table.

Toolbar : Polyline Tool Set 2
      Menu : GeoTools Polyline Tool Set 2 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.

      Menu : GeoTools Polyline Tool Set 2 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

Toolbar : Polyline Tool Set 2  
      Menu : GeoTools Polyline Tool Set 2 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>
Select second polyline: <do so>

      Menu : GeoTools Polyline Tool Set 2 Multiple vertex editor for polylines, lines and arcs. 
Command line : GT_MVEDIT

The GT_MVEDIT command is used to edit multiple vertex positions from multiple selected polylines, lines and arcs.

With the GT_MVEDIT command, you can move multiple vertices from many objects at once in the X, Y, Z, XY, YZ, XZ or XYZ directions while keeping the other coordinate unchanged. Think of this as a tool similar to the XYZ point filters in AutoCAD and Bricscad, but applied across multiple objects and multiple selected points of a polyline, line or arc.

Toolbar : Polyline Tool Set 2  
      Menu : GeoTools Polyline Tool Set 2 Set or remove flowing linetypes for polylines
Command line: GT_FLOW_LT 

In  AutoCAD / Bricscad , polylines can be set with a flag to determine if flowing linetypes are enabled or not. When flowing linetypes are enabled, the linetype pattern and scale are applied continuously across even small length segments thereby generating the linetype correctly. If this flag is disabled, the linetype pattern is applied each time at the start of a new segment. This may cause improper representation of the linetype in a polyline with very short segments. This command provides a means to set or remove flowing linetypes from selected polylines.  

Toolbar : Polyline Tool Set 2
      Menu : GeoTools Polyline Tool Set 2 Delete single vertex polylines
Command line: GT_DELSVP

The GT_DELSVP command deletes a single vertex or zero-length polyline from the selected objects. Unlike the GT_0LEN2PNT command which creates a point at every location of a zero-length polyline, this command will delete it from the draiwng.
