A system, method, and computer program product which allows more versatile manual and automatic edits by embedding behaviors in the curve elements. These imbedded behaviors allow intelligent shape preservation during a curve edit. Each curve carries a behavior property that describes how it should react when edited. This means that the curve and graphics system have full knowledge of the right edit type to make, even when triggered by an outside source, such as a re- compute of an object at a higher level in the feature tree.
