2008.03.646 09-07-12   Geo Construction 2008
    Alignments Changes in clothoid calculations.
Traditionally SBG have used an approximation for calculating coordinates on a Clothoid. The approximation has been known to have a limited range of validity. However, the approximation has been well established in road/rail construction engineering so until now there have been little reason for changing it. Recently, it have been demonstrated that there are applications where the range of validity is exceeded, resulting in incorrect results. Therefore the calculation routines have been changed. The change only affects clothoids with a curvature that are close to (or longer) than a quarter of a circle, or such ones that are far away from the segment of infinite radius.

As long as data is imported and used in applications where this change is present there is no problem. But if you send imported or edited data to other applications there might be a problem. Versions of Geo, GeoPad and GeoROG/UMC3D that are not adjusted for this will not calculate coordinates correctly. For this reason, always run a line check in the application where the line will be used, even if you don't intend to modify it.

The line check in Geo has been extended to show an information message if the line consists of clothoids that can cause these kinds of problems in older versions of Geo, GeoPad and GeoROG/UMC3D. .
    Coordinate Calculation Improved correction for earth curvature.
    Coordinate systems Possibility to select the version of the localization file (lok) when saving it, in order to be used in products that can't handle the latest version.

    LandXML import Automatic 3D curve interpolation to stringlines can be done directly when importing LandXML files that contains some form of standardized coding (Leica/Trimble/Bentley).
    LandXML export Export of coordinates to LandXML, the order of the line codes was adjusted to work in Mikrofyn's Visual Machine.
    LandXML export Export of coordinate files with lines to LandXML, the file is adjusted to be imported in Leica LGO/TMS Office and Trimble TGO. The element type "Line" is used instead of "IrregularLine" when possible.

2008.01.611 08-04-09    Geo Construction 2008
    Coordinate Calculation The suggested name of the report conflicted with the name of the measuremnt file, with the risc of overwriting it. This is now fixed.
    The Project Tree Improved updating.
    Import/Export SOSI Various improvements in the file conversion.
    Coordinate files/graphics If the line code is set it will be used for control of the line type to use in the graphics. Otherwise the code of the first point in the line will be used. Also applies for AutoCAD export.
    Import/export The instrument related formats were moved to the top of the menu.
    Licensing User name and company can now be set even when using certificates.

    Roadlines It's now possible to extract plane coordinates from a cross section file by selecting a line reference.
    Graphics

New dialog for files in graphical windows. It's now column-based, so it's easier to view files with long search paths. You can also turn off point numbers, height and codes for many files simultaneously.

    Graphics, AutoCAD You can select which AutoCAD version you want to use by default when you save .dwg or .dxf files.
    Graphics, AutoCAD Frozen layers in dwg files were visible in 3D-views. Fixed.
