研究了基于草图轮廓的拉伸与旋转特征模型重建的生成方法，以实例零件说明本文提出的重建方法是切实可行的。
The generation methods of sketch-based feature model reconstruction are presented in this thesis. Experimental results show that the methods presented here are reliable.
大多数的三维雕像，无论是站立的、坐着的还是跪着的，都表现出一种被称为“正面描绘”的特征：它们面向正前方，既不扭曲也不旋转。
The majority of three-dimensional representations, whether standing, seated, or kneeling, exhibit what is called frontality: they face straight ahead, neither twisting nor turning.
考虑添加其他手势识别，例如通过从synclient输出中进一步提取特征来识别按压旋转动作。
Consider adding additional gesture recognition, such as pinch rotate through further feature extraction from the synclient output.
