This February software update brings two bug fixes and two new features. The bug fixes listed are; concentrated on calculation error concerning user defined start/end chainage, and imported data is not available for viewing or editing. While the additional features consist of; new annotation labels in debug view mode and an added function to raise/lower vertical alignment.

Bugfix 1: Concentrated on calculation error concerning user defined start/end chainage
In the previous software version it was reported that when using the calculation or re- analyse option and the NovaTrack 3.0 regression with the user defined start/end chainages, an invalid horizontal alignment result was produced. The new software version contains corrections to the horizontal alignment calculation engine when an alignment calculation needs to be done in the user defined chainage range.
After completing the alignment, the automatic calculation is within the set chainage range and the remaining part of measurements outside the specified chainage range will not be displayed. They are still stored in the project. Project recalculation with a different chainage range would not require measurement data to be re-imported as the measured point information will be taken from *.SPW project. A user defined calculation range requires that measurements start/end in a straight line or circular curve segments (at least >50 m in beginning and at the end of the range). Additionally, in the calculation profile it is recommended to adjust the parameter “error_tolerance_offset_pnts” value to fit between 30-50%.
Bugfix 2: Imported data is not available for viewing or editing
When no alignment solution was generated, the software was incorrectly determining an active view area in all display windows when the horizontal alignment calculation used “NovaTrack 3.0” or “Regression with transition curves”.
This was resulting in the incorrect data limit estimation and further zooming. After an invalid horizontal alignment calculation, the measurement data was not visible when applying “Zoom previous”, “Zoom extents”, “Zoom out 2x” or “Pan” commands and would require the end-user to re-import the measurement data. In the new software version, this issue has been resolved and data visibility is determined by the min./max. coordinates of the measurement data area.
Added Features
Feature 1: New annotation labels in Debug view mode
In the new version there is a possibility of using “x/X” key to activate/deactivate measured point label information. The label content is different between points in the horizontal and vertical views. Offset information in the point label is automatically updated while editing alignment elements.
Feature 2: Added function to raise/lower vertical alignment
The newly implemented feature offers a possibility to raise or lower the vertical alignment by entering a relative offset to all PVI points. The change, by raising or lowering a vertical alignment, has no effect on vertical alignment geometry. This function is very useful when the design alignment requires uplift to minimize the amount of negative vertical offsets (when the design is below the actual track height) without recalculating the complete geometry. Alignment lifting is set with positive and lowering with negative PVI height offset value.
