enhanced or changed
GT_FLIP : [Polyline Tools - Flip (reverse) directions] :
Two new options have been added to this command. You can now flip
polylines based on the values of the first and last point elevations.
Depending on whether the first point elevation is lesser than or
greater than the last point elevation, you can reverse the direction of
the polyline. This is a very useful tool in many surveying and mapping
applications where you expect polylines to be flowing in either
increasing or decreasing z values. This command helps to identify such
flows and reverse them. Please be aware that this tool only looks at
the first and last point elevations and does not check the intermediate
vertex elevation values for any reason.
In the future, we plan to come up with a more "intelligent" polyline
elevation analyzer program that would also study the pattern on
intermediate elevations and check if there are intermediate segments
that violate the desired flow of the vertices.
GT_3DOFFSET : [Polyline Tools - 3d offset of polylines] :
The internal mechanism of this command has been altered slightly to
overcome some bugs which would show up while handling some situations
of 3d polyline vertices. The program is now more stable and
error-proof. These changes affect only the handling of offsets when the
number of vertices between the source and offsetted polylines are not
GT_REPBLK : (Block Tools - Replace blocks) :
The GT_REPBLK command now allows a manual selection of blocks to be
made for block replacement. The earlier way of working would replcae
every instance of one block with another. This has now been changed.
Additionally, this command now retains both extended entity data as
well as object table data while replacing one block with another.
GT_SCALE_Z (Miscellaneous Tools -
Scale Z elevation values):
This command now has its edit box width increased to 8. So, you can add
more number of digits to the precision of the values that you are
GT_LINE2PL : (Polyline/Conversion Tools - Convert lines and
arcs/circles to polyline):
GT_3DF2PL : (Conversion/Polyline Tools - 3DFaces to polylines)
GT_3DF2PFACE : (Conversion Tools - 3DFaces to polyface mesh)
GT_PFACE2PL : (Conversion Tools - Polyface mesh to polylines)
GT_CH3D2D : (Polyline Tools - Convert 3D-to-2D polylines)
GT_CH2D3D : (Polyline Tools - Convert 2D-to-3D polylines)
GT_XP_RETDADT: (Miscellaneous Tools - Explode objects, retain Xdata and
GT_REPBLK : (Block Tools - Replace Blocks)
All of the above commands have been enhanced to retain both extended
entity data and object table data while entities are transformed from
source to target.
GT_OD_SEARCH (Autodesk Map Tools - Search and replace Object
The GT_OD_SEARCH command now has an option to just do the
Search without the Replace.
There is a new option called 'Replace Values' which, if checked,
performs a search and replace operation. If it is not checked, only a
search is performed and the objects meeting the search criteria will be
placed in the active selection set. Some other bugs in this command
have been fixed.
GT_XP_RETDAT : (Miscellaneous Tools - Retain object
table data and extended entity data):
The GT_XP_RETDAT command has now
been enhanced and it can now explode REGION objects and retain their
object data and extented entity data in their exploded polyline form.
GT_IMPEX: (Export Tools -
Import/Export points and lines) - The GT_IMPEX command now has
additional options to handle exporting of linear features.
The following enhancements to the GT_IMPEX command have been done in
1. You can now optionally create a blank line between two line/polygon
2. You can now optionally use a different last point elevation
identifier for line/polygon records. If this option is checked, the
last elevation of each line or polyline record will have a different
elevation string as entered in the edit box below. This feature is
provided because some systems identify the end of a line/polyline by
reading a special value set in the elevation field of the last point.
3. You can now overwrite an existing output file or simply append to
Progress Indicator Interval :
Often, GeoTools displays a progress indicator by way of an
informative message on the command line that indicates how many objects
have been processed and how many are remaining to be processed.
Until now, the progress indicator message was updated for each object
that was being processed. This can be quite time-consuming when large
data-sets have to be processed and it takes up significant computing
time. To overcome this, we are introducing a parameter called 'Progress
Indicator Interval' in the General Settings dialog box (GT_GENSET
Here, you can now specify the progress indicator interval you want. So,
if you specify 100 as the interval, the progress indicator will refresh
itself only once each 100 objects are processed. This speeds up
GT_ASN_PROP: (Assign inherited properties from neighboring
objects - Conversion Tools) : The GT_ASN_PROP command can now
assign to each vertex of a 3d polyline elevation values inherited from
neigbouring text or block attributes.
GT_MODTXT: (Globally Modify Text/MText objects): This
command now has an added option to trim characters from the beginning
or end of a string of text/mtext upto a specifed marker character. The
marker character should be a single character that has to be specified
in the object edit box labelled "Enter value for selected property"
Bug Fix & Enhancement : GT_DENSIFY : The GT_DENSIFY
command has now been bug fixed and updated. The command now correctly
interpolates the in-between added vertices and it acquires 3d
elevations correctly by interpolation.
There have been some minor changes in the program options. The option
to measure distances by 'Slope' or 'Horizontal' has been removed and
the program now measures in Slope only. The option to "Interpolate" 3d
polyline vertices has been removed and interpolation is now automatic
for 3d polylines.
GT_NEWSTART : (Polyline Tools - Specify a new start for
closed polylines) :
The GT_NEWSTART command has a small bug fixed.
Whether the polylines had an explicit closing vertex duplicated as
first vertex or not (implicit closing), the same structure is now
carried forward to the new polyline with its modified start point.
Earlier, no matter what the original polyline was, the new polyline had
its last point duplicated explicitly as the first point.
