Sketchup C Api meshhelpref give me wrong normals


i am not sure about the way i use the C api . i want to develop a tool to transform .skp to a middle file that can be used by UE4.0. now i found a pillow component cannot be transformed correctly.
the orignal file is
original file
(file is bigger than the limitation , so i upload it to google drive)
a part of faces is correctly displayed. the other is wrong.


The original SketchUp file is incorrect. Enable “Monochrome” to see. The blue faces are reverse faces.


To fix, enable “Hidden Geometry”, open the component for editing, right-click one face, then select “Orient Faces”


thank you so much for your reply. this is really helpful. now it can be transformed correctly.
