摘要
在进行3D建模时,为了能高效正确的进入草绘环境,必须进行草绘设置。草绘设置的方式较多,定义较为复杂,本文提出了草绘设置的两种方法,一是根据定义直接设置,也就是在绘图区域可以直接选取草绘平面;另一种方法是间接设置,也就是在绘图区域无法直接选取草绘平面,而是根据特征的内涵,通过定义轨迹,截面方向、截面之间的几何关系等来间接设置的。明确了这两种方法,可以使工程技术人员有意识,有目的,有步骤的进行草绘设置,从而提高设计效益。
In 3-d modeling,in order to enter effectively and correctly into the sketch environment,sketch setup must be conducted,to which there are various approaches,and its definition is complex. This paper presents two methods for sketch setup. The first one is direct setup,that is,one can directly select sketch surface in the drawing area. Another is indirect setup,that is,one cannot choose sketch surface directly in the drawing area,but set up indirectly by defining the trajectory,the geometric relationships between the cross-section direction and cross section according to the features of the connotation. A clear idea of the two methods can help engineering technical personnel to carry on the setup consciously,purposefully,and step by step,so as to improve design efficiency.
