In conventional design CAD system, designing the intended curve segment is time-consuming and labor-intensive due to the nature of the curves. Though there are tools within CAD to help reconstruct curves, their performance has been reported insufficient. In this paper, we present a method for curve reconstruction that is based on The Experiential Design Guidelines to facilitate design work. Firstly, the input curve is subdivided according to the guidelines, then reconstructed by the curve interpolation technique. Finally, the resulting curve is optimized to fully meet the Experiential Design Guidelines. The objective function to be minimized is a weighed combination of two components associated with the coherence to the original design, and the curvature approximation by second derivative. The importance of the two components is weigh by a user-defined parameter. Numerical examples demonstrated the effectiveness of the method. However, there remains some problems for further improvements.
