Why do I get "Maximum deviation is 0.001378" Alert on a Variational Sweep displayed in PNT when hovering over the feature?
Solution
According to Siemens dev. on PR9371481, which was converted to ER:
This is an information warning indicating there is a small deviation between the "procedural" definition of the surface and its b-spline surface result. These cases would have failed in pre-NX11.0.1. We implemented a project in NX11.0.1 where we allow the result sheet creation even if the result is not perfectly within the distance tolerance. These results are usable for most cases. The variational sweep algorithm performs an adaptive least squares fitting of the evaluated section along the path into one or many b-spline surfaces. The algorithm typically adds more sections until the deviation is within tolerance. This strategy breaks down sometimes. Whenever the algorithm inserts too many sections that are too close to one another, the classic b-spline oscillation effect takes place and the convergence cannot be reached and it fails. The algorithm was enhanced to prevent this. Whenever, the deviation cannot be reduced, the algorithm stops inserting sections and produce the result found so far. An information diagnostic is created to let the user know.
