Abstract
This paper presents a freehand, sketch-based interface for Computed Aided Design (CAD) engineering design and finite element analysis. After a user sketches a two dimensional sketch consisting of connected straight and curved strokes, the sketch is processed by two optimization-based reconstruction algorithms that can reconstruct sketches of 3D objects made up of straight lines and planar curves. The proposed implementation allows certain types of objects with over 50 strokes to be reconstructed in interactive time. Following reconstruction, the structural properties of the 3D shape can be examined using finite element analysis. The object can quickly be modified using the pen-based interface according to the results of the analysis. The combination of a rapid, sketch-based design interface and finite element analysis allows users to iteratively design, analyze and modify 3D objects in an intuitive and flexible way.
