Medial axis(MA) is a dimension-reduced representation for 2D/3D objects and widely used in finite element analysis(FEA). However it is very time consuming to computing MA from the scratch. In this study, a novel approach to generating the exact MA with local adaptation is proposed for polygons. The region where MA is to be changed is found out first. And then MA of the region is calculated and further it is combined with the unchanged MA to obtain the final MA for the whole part. The algorithm is implemented with ACIS 6.0 and some examples are given.
