The software is built on a technology called Rapid Blue. It lets
users directly edit models' topology. Parametric models maintain
their intelligence while surfacing components change part shapes
in ways not previously possible in Solid Edge. Rapid Blue
dynamically edits surfaces with shape preserving curves and
capabilities called Blue Dots and Blue Surfs. Because the
technology builds on parametric models, it is not constrained by
modeling history the way solids are. It is more of a process
system than a historical one.  Shape-preserving curves minimize
changes to an original design intent while still exploring
alternatives. Users control curves by vertices, points, even
silhouette points Ñ all without disturbing parametric sketch
constraints. Contour curves can be placed directly on surfaces.
Cross curves can be created by projecting 2D geometry. And
intersection or pierce points can be created where curve or edge
entities intersect a sketch. These points can be constrained or
modified as needed. You can ev
