*** Special announcement *** : GeoTools add-on module 'GDFViewer'

This update of GeoTools adds a completely new add-on module called 'GDFViewer' to GeoTools.

This is the first add-on module we are adding to GeoTools and the GDF Viewer is available at an introductory price of USD 99.00 only and is currently available for purchase only as an add-on module to GeoTools i.e you will need to purchase a license of GeoTools in order to purchase 'GDFViewer'.

The Geographic Data Files (GDF) are used to model road network data for navigation purposes.

The GDF Viewer is a separately priced add-module to GeoTools and contains a set of routines that can be used to view, query, analyze and compare GDF files within the AutoCAD environment.

The GDF Viewer commands are available under a newly-created pull-down menu within the GeoTools pull-down menu. Currently, the following commands are available:

IG_IMPORTGDF : Import GDF file
ID_VIEWGDF : View/Query GDF objects selectively
ID_SECTEXTRACT : Extract GDF sections (useful to split-up huge GDF data-sets)
ID_SEARCHGDF : Search GDF files for specific GDF objects
ID_GDFCOMPARE : Compare two GDF file structure (Record definition only)
ID_COMPAN : Analyze Complex Features
ID_RELQRY : Query Relationship records

The GDF Viewer is still in development and there is a long way to go to be able to handle all complexities of GDF data modelling. Your feedback and comments are more welcome. What we have assembled here is our first effort at understanding the GDF data format and trying to bring in that data into the AutoCAD environment.

There are still a number of glitches and known and hidden bugs in the program and we are attempting to refine and improve the program as much as our schedule permits.

This update of GeoTools has some important bug fixes and improvements in place:

GeoTools global change:

All GeoTools commands are designed to function correctly only when the default AutoCAD angle measurement direction
is counter-clockwise. This is the default setting in AutoCAD. Every GeoTools command now automatically saves the current
setting of the angle direction at the start and restores it back at the completion of the command. This ensures that
during the running of each command, GeoTools internally works with an anti-clock-wise angle measurement direction (as
designed) and it is reset at the end. In earlier versions of the program, some commands like those that used angular
measurements would orient incorrectly if the angle direction was clock-wise. This is now 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 asap. 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.
