Summary0026138: Problems with writing periodic BSplines into IGES
DescriptionAfter write and read operations some periodic BSplines changes its geometry: additional knots appear, surface becomes rational, therefore faces on these surfaces have problems with pcurves and change the form.

In the attached picture there are screens of the initial face, the face after writing-reading, and both faces to show difference.
