After generating the modified terrain, the following window will appear detailing the different errors found. These errors are classified as "Warnings" or "Errors" depending on their degree of influence on the road definition. In the former the road has been generated and in the latter its composition is impossible in the station specified.
The following displays the error window that appears after the generation process.
The list displays the error report and at the bottom are the different classifications.
Errors: The list only displays the errors found during the generation process.
Warnings: In this case it only shows the warnings.
Summarized: Displays the list grouped by stations with the same type of incident.
Detailed: A station-by-station list of the errors found at each station.
By clicking on the Check button (only if Detailed is checked), the command corresponding to the error found is activated and any changes necessary can be made. If the Regenerate button is then clicked, MDT will calculate the new segment.
It will then display a list of different possible errors and their error category.
Station not generated. No intersection with terrain
Cause: When generating the cross-sections, the corresponding cut was not created as the objects selected are not cut.
Solution: Check whether the drawing or horizontal alignment is correctly defined.
Left/right-hand slope does not intersect terrain
Cause: When assigning the slope that cuts the natural terrain with a code, the code entered is not found in the terrain.
Solution: Check slope assignment to see if the code entered is correct.
Too many vertices on slope
Cause: The slope’s definition contains too many vertices.
Solution: An erroneous height difference may exist between the grade line and the natural terrain, thereby creating an excessive number of berms on the slope.
Too many vertices in ditch
Cause: The ditch’s definition contains too many vertices.
Solution: There may be an erroneous height difference between the grade line and the natural terrain.
Slope assigned does not exist
Cause: A slope has been assigned which has not been previously defined.
Solution: Execute the Sections > Definition of Slopes command and define the appropriate slope.
Platform assigned does not exist
Cause: A platform has been assigned which has not been previously defined.
Solution: Execute the Sections > Definition of Platforms command and define the appropriate platform.
Left/right roadbed creation error
Cause: MDT has detected an error when generating the roadbed associated to the section type at the specified station.
Solution: Check in Sections > Definition of Roadbeds the roadbed assigned to the station in question and the criterion defined.
Cross-section definition does not exist
Cause: The natural terrain associated to the segment contains no information or is corrupt.
Solution: It would be advisable to obtain the profiles associated to the work again. In order do so, execute the command Cross-Sections > Obtain Profiles.
Geology assignment not found on left/right slope
Cause: The definition of the terrain’s geology associated to the definition of the section’s slope does not exist or is incomplete.
Solution: Execute the Templates > Assignment of Templates to Horizontal Alignment command, activate the Geology option and configure it properly.
There is no left/right slope assignment
Cause: No slope assignment has been defined.
Solution: Execute the command Templates Type > Assignment of Templates to horizontal alignment
and configure slope assignment at the stations where the problem appears.
Vertical alignment does not exist
Cause: The segment has no grade line information associated to it.
Solution: Execute the Vertical Alignment > Define Vertical Alignment command and insert it in the segment.
Platform assignment does not exist
Cause: The platform has not been assigned to the section template.
Solution: Execute the Section Template > Assignment of Templates to Alignment command and assign the relevant platform to the station concerned.
Platform not found
Cause: MDT is attempting to assign a platform to a station, which has not been defined or has been deleted.
Solution: Execute the command Templates > Definition of Platforms and define the appropriate platform for the station.
Station does not exist on alignment
Cause: The station it is trying to process is not defined on the horizontal alignment.
Solution: The horizontal alignment associated to the segment may contain corrupt information or the segment may have a horizontal alignment assigned that does not correspond to it.
