Overview: Patterning a feature on a model can be a powerful away to leverage the parametric nature of Pro/E. There are times however when the size of pattern becomes so large that regeneration times become unacceptably long or you run into situations where a feature is created without proper references to allow it to be patterned at all using the conventional commands available. Surface transforms leverage the power of Pro/E surfacing by both reducing regeneration times as well as allowing you to create patterns of features that were previously impossible to pattern. Metric: The example used in this tutorial was of a carrier for a semiconductor chip. Before surface transforms were used, this model took 25 minutes to regenerate. After the surface transform technique was applied, regeneration went down to 5 minutes. This is an 80% reduction in ...
