Building the road task

How long road model can I build?

Answer: Few limitations, but the actual length are non of them:

• 30000 cross-sections
• 2500 horizontal elements on the alignment geometry

What affects the calculation time for my road task?

Answer:There are a couple of different factors affecting the calculation time for any given road task:

• Total number of cross-sections
• Amount of data in each cross-section (number of features, and total number of points to process)
• Calculation Basis
• Illustration Objects
• Search width
• Level of detail on the terrain and subsurface layers (when joining the cut/fill solids)
• Overlapping cross-sections (in tight corners or in intersection areas)
• Terrain and subsurface layers that are not defined good enough so that they vary which one is on top for each section
• It will make cut-solids with potentially thousands of holes which takes time to process.

TIP: When considering if your model is slow or not, please evaluate the process info to determine if it is the gathering and building of cross-sections or the 3D production that is of concern. </note>

Road calculation is updating alignments during build when it shouldn't

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

Note: From Novapoint 2020 it will detect if any Line tasks should be updated, and if not, turn off the setting automatically.

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 trips when not have a starting surface defined in it's "Start surface"-description.

Novapoint shuts down when trying to build roadmodel. Is there any way to solve this problem?

Answer: This is a possible Workaround: If you right-click on Road task and select Edit task, you can go to Settings under the Design tab. Here you can uncheck Create Solids. Please see the attached picture.
