** New command added:
GT_JUNCTION: (Polyline Tools & Drawing Cleanup Tools - Mark junction points on a network of linear objects: The GT_JUNCTION command creates points at every junction node. A junction is defined as a point where atleast three or more segments branch out in as many different directions. So, if you have a network of lines (or polylines) representing a road, parcels boundaries or any similar linear/polygon feature, this command helps to identify every junction by creating a point object at that location.

Please be aware that this command is somewhat similar (and different) from the GT_INTERSECT command (also in Polyline Tools & Drawing Cleanup Tools), which creates a point at every segmental intersection, while the GT_JUNCTION command creates points at every junction or node where there is an explicit vertex or end point of ARC or LINE. In other words, the GT_JUNCTION command does not identify segmental intersection (where there is no vertex present). Instead, it locates nodes where there are three or more segments originating and marks points on them.

** Enhanced commands:

GT_FILLETPOLY (Polyline Tools - Enhanced fillet command): The GT_FILLETPOLY command has been enhanced and its scope widened. The command is now offered
as a replacement for the standard AutoCAD fillet command, which has several short-comings. For example, the AutoCAD 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.

GT_3DOFFSET (Polyline Tools & Build Tools) - The GT_3DOFFSET command has been enhanced with an additional option called vertical offset. With this, you can now offset a 3d polyline both horizontally as well as vertically in the Z direction. This can be a very useful tool in several civil engineering situations where you want the ofsetted polyline to be elevated or lowered by a fixed amount relative to the source polyline.

** Bugs fixed

GT_CHCASE command (Text Tools - Change case): The GT_CHCASE command was not working correctly on multi-line MTEXT objects when the case change option was either "Lower" or "Mixed-Case". This has now been fixed.

GT_CONS_TXT command (Text Tools - Consolidate text into MText): The GT_CONS_TXT command was not working correctly. It would remove the 'U' character from text strings if it happened to be the first character of the string. This has now been fixed.


Important note: While all of GeoTools commands are tested quite extensively before they are released, it is humanly impossible to test-run it under every different data type or operating environment. In the event that you notice any GeoTools command not functioning as expected, please bring it to our notice as soon as possible. We will attend to it and fix the problem as soon as possible.


Thank you for your continued support. As always, we welcome feedback at all times.
