What's New in Version 6.x

Version 6.x has many new features. These are listed below. For detailed descriptions, refer to the appropriate help topic as underlined.

BACKGROUND IMAGES

LISCAD now has a new task which allows background raster images to be registered and imported into SEE files. Any number of images can be imported and 4 transformation methods are available to register different image types. BMP, JPG, TIF, GIF and PNG image format types are supported. To get an understanding of how LISCAD works with background images refer to Background Image Concepts.

The following functionality is now available to support background images:

FIELD

Leica TC Class Instruments Supported

Data Recorder input and output now has the ability to interface to Leica TC Class Total Stations. You can upload a Format file to the instrument that will allow collected data to be downloaded and processed, also all LEICA/WILD Operation Codes are fully supported. The ability to select from a list of jobs to download from the total station has also been included.

Leica Field Operation Codes Enhancements - (Also supported in LISCAD Lite)

Operation Code -6 has been enhanced. It now allows an Offset Distance to be entered (-ve left, +ve right).

Operation Code -19 allows the removal of an elevation from the current point and all points following (after the observation).

Operation Code 30 and 31 have been enhanced. Entering 3 for the Elevation flag will result in the average elevation being transferred to the system created symbol origin point and the elevations of the two edge points being flagged as non-contourable. These two points will not be included in the currently running string and will both be placed on the construction group.

Operation Code 32 has been enhanced. Set the Point ID as -1 if the previously observed point is to be used to set the direction.

Operation Code -32 is used to create an isolated symbol of a defined code with its direction being defined by the direction of the observed point to a previously defined point. It is entered after the observation to the point.

Operation Code 33 has been enhanced. The symbols of the two measured points are now removed. Also, entering 3 for the Elevation flag will result in the average elevation being transferred to the system created symbol origin point and the elevations of the two edge points being flagged as non-contourable. These two points will not be included in the currently running string and will both be placed on the construction group.

Operation Code 34 allows the creation of a Symbol with a defined direction (after the observation).

Operation Code -34 allows the creation of an Isolated Symbol with a defined direction (after the observation).

Operation Code 35 creates a symbol with the feature code entered. It's edge position and height are defined by the first two measured edge points and the width is defined by the third measured point, computed as an offset to the first two points (after the first observation).

Operation Code 36 creates a fully defined Symbol at one measured point with the direction defined from a second measured point (after the observation). Also if the construction flag is set, the symbol and its direction point will be removed from any currently running string and the direction point will be placed on the construction group.

Operation Code 74 has been enhanced and now has an Elevation Flag. Use 0 for 'No Elevation', 1 to take the elevation of the first point, 2 to take the elevation of the second point and 3 to take the elevation as the mean of the two points.

Operation Code 75 creates secant or offset points (joined by a line to the measured point if the code is stringable). The constructed points use the attributes of the feature code as well as the line if created. Only ONE Secant/Offset operation code can be entered at a point.

DATA CONVERSIONS

LISCAD can now directly import AutoCAD DWG (*.dwg) drawing files and AutoCAD DXB (*.dxb). DXB is a drawing exchange binary format and is the binary equivalent of DXF. DXF (*.dxf) import is also still supported.

CAD OUTPUT

Output of AutoCAD DWG drawing files are now directly supported. This includes the following versions:

AutoCAD 2000 Drawing (*.dwg)

AutoCAD Release 14 Drawing (*.dwg)

AutoCAD Lite 98 Drawing (*.dwg)

AutoCAD Lite 97 Drawing (*.dwg)

AutoCAD Release 13 Drawing (*.dwg)

AutoCAD Lite 95 Drawing (*.dwg)

DXF is still supported and has been enhanced to support a number of AutoCAD versions including:

AutoCAD 2000 DXF (*.dxf)

AutoCAD Release 14 DXF (*.dxf)

AutoCAD Lite 98 DXF (*.dxf)

AutoCAD Lite 97 DXF (*.dxf)

AutoCAD Release 13 DXF (*.dxf)

AutoCAD Lite 95 DXF (*.dxf)

AutoCAD Release 12 DXF (*.dxf)

AutoCAD Lite 2 DXF (*.dxf)

CAD Output has also been improved to give you the option of using AutoCAD prototype drawings and fonts. The prototype drawing contains all the symbols (defined as blocks) and line-style definitions you will use.
