CivilConnection: Unable to send curved elements from Revit to Civil3d

Hello,
I am trying to send Revit family to Civil3d using “LinkElement” from CivilConnection package. I was able to achieve it for most of the revit families. But when I send families with curvature such as pipes and curved barriers I get the error as below:
Unable to Compute edge from curve: IG_ELL_NML_NOT_PERP – Ellipse normal not perpendicular

Kindly help me to resolve the issue to send curved geometries.
Thanks!
