Bug Extruding Closed Planar Polyline

Guys I’m hoping this is just a bug and not improved new feature but in the current WIP6 ( 6.0.17031.12411, 1/31/2017 ) extruding closed planar polyline returns single surface plus two caps. Same thing while lofting two planar close polylines, result in one surface. Now I have to explode them all or end up with useless geometry.


Ignore that. I had split at tangents unchecked… sheesh…
