Hi ? Could you sign with your first name so we know how to address you, thanks.
If the binding of the normals is BIND_PER_PRIMITIVE then you will get a faceted appearance, and is obviously indented by the original data unless the export/import is broken. Do you see the same results in SolidWorks as in the OSG when you don't invoke any smoothing. If you do wish to override the BIND_PER_PRIMITIVE and have the OSG compute per vertex normals for you then the osgUtil::SmoothingVisitor is the tool for the job. The modification that Wang Rui made was to address a crash when the normal BIND_PER_PERIMITIVE and should have allowed you to run the visitor on the data set. Beyond this I can't really add much. In theory it should work, but without the dataset to test against myself or any screen shots of what is wrong, and without details of what settings you are using I can't really say whether anything is wrong or whether it's just your settings and expectations of the results that is amiss. You'll need to provide more details to allow others to make some suggestions. Cheers, Robert.
