CivilConnection-Corridor Target

I create an assembly with offset target left and right use it to create a corridor in Civil 3d and use the civil connection package to create a solid geometry in revit. Corridor shown with in civil 3d is correct.

but in Revit it show smooth edges.

i don’t know what did i missed. I’m new in using CivilConnection and dynamo. Any idea what went wrong?
