Problem importing corridors from Civil 3D

[Irena.antolin]

Hello,

I have trouble importing corridors into Infraworks using the command import Autodesk Civil 3D DWG.

In Civil 3D I have a corridor consisting of several baslines at an intersection (Picture 1), but in Infraworks, there are space between centerline basline and edge baselins (Picture 2).

I have InfraWorks 2021.1 and Civil 3D 2021.1.1

Picture 1:

Any help or ideas would be greatly appreciated! Thanks in advance!

@Irena.antolin  From the image, seems the alignment geometries are changed during the import process. could you please check geometries of those alignments?  

There is a known issue if alignment contains floating curve and spiral. 

Hope helps,

Thanks
