Hi
I am using CivilConnection to read the Civil 3D corridor with assemblies created with Subassembly Composer, but I have a problem; I did the assembly of a hollow pipe, Civil 3D visualizes them well, but when I bring it to Revit it looks solid, this not only happens with Created Assemblies, it also happens with Civil 3D, can anyone tell me how to fix this problem?

The code used in DynamoRevit is that of @Paolo_Emilio_Serra1,
Thanks
