Force rebuild corridor

Civil 3D
1

Hi,

any ideas how to trigger Rebuild() for Corridors?
The script updates AppliedSubassembly parameters in all sections, then all BaselineRegions and Baselines are manually flagged as NeedsProcessing. Despite all of that neither Corridor.Rebuild() nor the Rebuild node does the corridor update. Only sending the FORCEUPDATECORRIDOR command triggers the rebuilding.

Thanks.

Hello @kovacsv

did you solve this? I have similar issue when programing custom subassemblies. You solution with the FORCEUPDATECORRIDOR works fine. However, after few hours of trying I circled back to corridor rebuild as it should work.

Here is directly written “Forces the corridor to rebuild.”
Civil3D API 2027 Documentation

So, it should rebuild corridor correctly. However, I use C# not python.

Best regards
