** Enhanced commands:

GT_TC (Draw Tools - Running Text Numbers): The GT_TC command has been enhanced. You now have the option to create incrementing character text along with numeric text. This option allows you to create text like A, B, C, D in sequence. Any starting character sequence can be used. Only the last character will be used for incremening. For example, if BLOCK-AA is the starting string, the subsequent counter strings will be BLOCK-AB, BLOCK-AC and so on.

GeoTools User manual enhanced: The GeoTools user manual has been considerably enhanced, made clearer and prettier.

GT_CCPOLY (Build Tools - Create closed polylines from a mass of networked polylines): The GT_CCPOLY command has been enhanced with more processing options
and parameters. You can now create closed polylines from individual edges using two methods - 'Automatic' and 'At selected points'

The 'Automatic' method is what was available in earlier versions of GT_CCPOLY. This method scans row-wise and column-wise across a rectangular user selected window area at user specified intervals and creates closed polylines using the AutoCAD 'BPoly' method. There are some additional layer filtering and performance tuning options built into the command now. For example, you can specify a set of layer names from which the polygon boundary edges must be used for BPoly operation intsead of using all visible entities. Additionally, you can also specify the Zoom scale (magnification) at which each point should be processed. If you set these two parameters appropriately as per your average polygon size, shape etc, you can benefit from considerably improved performance in handling large data-sets.

The 'At selected points' method is another way to create closed polylines and should be used when you know the exact locations of the point within the polygons. For instance, if you already have label points around which you want to build closed polylines, this is the method to use. This method can often be more reliable and faster than the automatic method but it requires that you create the internal points for 'BPoly' yourself.

We have provided you with both options so that, depending on your drawing and data situation, you can use whichever works best for you.

Please bear in mind that the GT_CCPOLY command uses the AutoCAD 'BPoly' feature internally. The GT_CCPOLY command is only a wrapper to the 'BPoly' command which will allow the 'BPoly' command to run multiple times in a user-configurable manner. All requirements of the 'BPoly' command like exactly snapped boundary edges must be satisfied for this command to produce correct results. The GT_CCPOLY command makes no checks to ensure that the boundary edges are topologically correct.

-------------------------------------------------------------------------

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.
