[ Rhino ] Rhino 6 files are not importing correctly in DataSmith

Description

Geometry from a Rhino 6 file is not importing correctly. When imported it has holes and tears in the mesh. The same file saved as Rhino 5 and imported looks fine.

Steps to Reproduce
  1. Download the attached .3dm files
  2. Open the UE4 Editor and create a blank Unreal Studio project
  3. Navigate to the Import DataSmith button, click the dropdown arrow, and select Import CAD
  4. Go to where sink.3dm and sink5.3dm are downloaded and import them

Results: sink.3dm (Rhino 6) imports with holes and tears

Expected: sink.3dm imports with the same quality as sink5.3dm
