Features offer a high-level approach to modeling shapes. However, in most commercial modeling packages, only a static set of freeform features is available. A new method for user-driven feature definition is presented, as well as a method to instantiate these user-defined features on a target surface. We propose the concept of a dual environment, in which the definition of a feature is maintained parallel to its instance on a target surface. This dual environment enables dynamic feature modeling, in which the user is able to change the definition of instantiated features on-the-fly.<\/jats:p>","DOI":"10.1115\/1.3130781","type":"journal-article","created":{"date-parts":[[2009,6,4]],"date-time":"2009-06-04T22:25:47Z","timestamp":1244154347000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":2,"title":["A Dual Environment for 3D Modeling With User-Defined Freeform Features"],"prefix":"10.1115","volume":"9","author":[{"given":"Thomas R.","family":"Langerak","sequence":"first","affiliation":[{"name":"Image Sciences Institute, University Medical Center Utrecht, P.O.
