Sketcher Overview What is a sketch? Sketch is a collection of curves constituting a profile. Profiles may be used to extruded or revolved features. Profiles may be used to define sections for free form features such as a swept feature or a through curves lofted surface. Shanghai Jiao Tong University 2

Sketcher Overview Why do you sketch? -When a design intent is well known and constraints can be quickly applied to satisfy that intent. When there is a need to iterate through a number of various solutions to validate a certain design intent. Shanghai Jiao Tong University 5
