It is not easy for beginners to draw high quality pictures. If computers modify beginner's unskillful pictures into high quality ones, we are happy in many cases. To this end, we consider to use the features of pictures drawn by experts in drawing. We proposed a support system that modifies an unskillful curve drawn by a beginner in drawing into a high quality one using the features of curves drawn by an expert in drawing [see, Morimoto et al., IWAIT2005]. The modified curve preserved impression of the beginner's curve while having features of the expert's curve. Although the system could treat one of the two edge curves of the silhouette line of a hand-drawn curve, it could not treat the strength (width) of the silhouette line. In this paper, we propose a method to treat not only the general form (skeleton line) but also the strength of the silhouette line. Using a prototype system of the method, we experimented whether high quality hand-drawn-like silhouette lines (with strengths) were made. As a result, we confirmed that our method was effective in making those silhouette lines.
