Building the road task

First recommendation when you have an error

  • Try to remember what changes you did to the road model before this error occured. It is probably some of these changes that resulted in the error message.
  • Try to turn off the different parts of the road model calculation to see if the issues disappear (Design > Settings > Elements. Try to turn off all checkboxes or parts of the calculation.

Road calculation is updating alignments during build

Answer: The road model is building with dynamic alignments.
Turn this off in the settings: Design > Settings > Elements > Update dynamic alignments

Road model builds multiple times instead of once

Answer: The road model is building with dynamic alignments.
Turn this off in the settings: Design > Settings > Elements > Update dynamic alignments

Road task takes a long time to build

Answer: There are many potential reasons for this and here we will try to shed light on some of the reasons.

  • One or multiple road task are used as illustration objects.
  • We recommend checking the need for all the road tasks
  • How are the amount of data in these road tasks as ill.objects? Many cross-sections`in the ill.objects being cut by the active road models cross-sections?
  • Very detailed terrain data
  • Try to simplify the terrain where the level of detail is not as important
  • Decrease the search width for the road model terrain cross-sections (Design > Settings > Terrain boundaries)
  • Poorly defined rocksurface that is supposed to be on the terrain elevation, but in reality going above/below the terrainsurface making many soil pockets to be created in the 3D-results.

Road calculation produces 30000 errors when calculating

Answer:

  • Has the road model a defined surface description?
  • Has the road model a defined terrain for any cross-sections?

Road model will not build past Step 1 and crashes

Answer: Sometimes the level of data in the calculation records overflow. This might stop the calculation. The reason could be detailed data and/or a big search width producing alot of data. Try to simplify the terrain or use a narrower search width.

In some cases the Landscaping description does not have a starting surface defined in it's “Start surface”-description.
