heal.abstract	This work puts forward concepts that enable the feature-based design of parts with free from surfaces in an analogous mode to those of established systems for classic regular surfaces, i.e. prismatic and conic geometry. A Bezier representation is used where features consist of surface patches. Feature parameters are derived by referring to control points of the respective control polyhedra. Features are divided into touching, non-touching and blending. Features are under positional and/or slope continuity constraints. Constraints are checked for validity and warning messages are given appropriately. A case study is presented where a telephone handset is designed on a prototype system which was developed on the basis of a commercially available surface modeller. This serves to highlight the issues of feature definition possibilities, number of patches, continuity, constraints and geometry engine. A number of alternatives to the basic handset design are presented for illustration of the points made as well as its NC machining.	en
