Abstract :
Easel, is a smart CAD package which attempts to analyse and tidy up sketches as a designer draws them. This paper presents an overview of the system, details of its user interface and the curve-fitting approach. The main part of the paper is concerned with automatic methods to infer and enforce geometric relations intended by the user. The authors also discuss their conclusions as regards performance
