**** Headlines Today:

CADPower is a general purpose productivity tool for .dwg CAD. Here is a roundup of new features added in the past few days.

GeoTools is a productivity software for geographic data users, benefitting mapping, surveying, facilities management and GIS-CAD users.

*** New additions in CADPower & GeoTools V 15.20

** CADPower V 15.20

* Most of the missing German language translations have been completed and updated in this version.

* Major enhancement: CP_CGRID: (CADPower -> Draw -> Geometry -> Construction Grid): Major improvements have been made in this command. It is now possible to create interactive rectangular and circular grids using manual distance inputs which specify the distance between the grid lines.

For example, while drawing rectangular grids, it is now possible to draw the next grid line by entering the perpendicular distance from the last drawn grid line. A positive value draws to the right of the first defining grid line and a negative value draws to the left of the grid line.

Similarly, while drawing interactive circular grids, it is now possible to enter the next grid line relative to the last grid line by specifying the distance from the inner grid point or the outer grid point. A value of '50i' indicates a distance of 50 from the inner point while '100o' indicates 100 distance from the outer grid point.

This version also provides the option to create cross-grid points in interactive circular mode. Cross grid points also can be created by pick or by entering distances from inner or outer grid points as indicated above.

* Enhancement: CP_GENSET: (CADPower -> Settings): The CP_GENSET command has been enhanced. Two new options have been added which will be implemented gradually through the software. The first one is called 'Beep on Error'. This setting allows a beep sound to be generated each time CADPower encounters an error. The default is 'No Beep' and the function remains dsiabled unless you explicitly set it on and select a beep sound from one of six different beep tones.

The second new option is 'Enable voice mode for important messages/errors'. Checking this option activates Windows speech tools to speak out the important prompts, messages or error notifications. This tool may be useful for those experiencing difficulties in readimg prompts on the command line or for those using the latest version of AutoCAD which makes it very difficult to read command-line prompts anyway.

** GeoTools V 15.20

* Most of the missing German language translations have been completed and updated in this version.

* An update on the tools to read GML files in GeoTools.

Background: GML (Geography Markup Language) files are a variant of the KML file and is a format defined by the Open Geospatial Consortium.

GML files are usually large, running into several hundreds of megabytes or even more. GeoTools provides two commands to process and import them. The first one is called GT_EXTRACTGMLFEATURES. It takes big GML files and splits them feature-wise into several smaller ones. This can result in several hundreds or thousands of smaller GML files, each of which is easier to handle than one single big file. The enhancement in this version allows the split to happen into sub-folders defined as feature names.

The second command GT_READGMLFEATURES reads each one of these smaller GML files and creates the features in the drawing. Since it is virtually impossible to select the required GML files for processing manually, the GT_READGMLFEATURES command provides an option to process the files feature-wise or folder-wise.

* New command added: GT_KML2DWG (GeoTools -> Geographic -> KML2DWG (Google Earth KML/Z Import): The GT_KML2DWG command reads a Google KML/KMZ file and imports the point, line and polygon features in CAD.

* New command added: GT_GEIMPORTIMAGE: (GeoTools -> Geographic -> GEIMPORTIMAGE [Google Earth Image Import]): The GT_GEIMPORTIMAGE command is a process tool to capture a view window in Google Earth and import the same into CAD. It is a semi-automatic assisted procedure that involves using Google Earth commands & operations in an exact step-by-step procedure and attach the current Google Earth view in CAD using geo-referenced coordinates.

The command relies on the ability of Google Earth to extract the cursor coordinates into clipboard memory. You are asked to zoom to the area of interest and position the cursor at the lower left and upper right coordinates as accurately as you can. The coordinates are captured in clipboard and accessed by CAD. You are then asked to save the image in Google Earth and the same is attached in CAD using the correct geo-referenced coordinates.

* Improvements in existing commands

GT_READGMLFEATURES: (GeoTools -> Export -> Import a single GML feature from file): Performance improvement message added in GT_READGMLFEATURES command: The GT_READGMLFEATURES command now has an additional option at the beginning which allows you to disable the UNDO log and AUTOSAVE feature. This can reduce disk-swapping and improve improve overall performance while working with very large files.

The GT_EXTRACTGMLFEATURES now has an additional option to create indicidual feature GML files in their own sub-folder. Earlier, all feature-wise extracted files from the master GML would go into one single folder. The ability to store their in their sub-folders make file management easier.

* Enhancement: GT_GENSET: (CADPower -> Settings): The GT_GENSET command has been enhanced. Two new options have been added which will be implemented gradually through the software. The first one is called 'Beep on Error'. This setting allows a beep sound to be generated each time CADPower encounters an error. The default is 'No Beep' and the function remains dsiabled unless you explicitly set it on and select a beep sound from one of six different beep tones.

The second new option is 'Enable voice mode for important messages/errors'. Checking this option activates Windows speech tools to speak out the important prompts, messages or error notifications. This tool may be useful for those experiencing difficulties to read prompts on the command line or for those using the latest version of AutoCAD which makes it very difficult to read command-line prompts anyway.
