    • System and methods for the creation graphic images (1200) include automatic pull-off creation and maintenance of tangent and perpendicular lines, creation and maintenance of objects satisfying mutual geometric relationships, the identification and processing of visual intersections (1202), and alignment in 3D space. Other techniques of the present invention include the automatic recognition of interesting points (1310), the use of screen messages to identify points (1201), the use of a secondary cursor, the creation of temporary geometry, the examination of interesting points (1310) which arise from actual geometry, temporary geometry, and/or the interaction of actual and temporary geometry, an precise graphic operations (e.g., drawing and transformations) with the assistance of interesting points (1310).
    • 用于创建图形图像的系统和方法(1200)包括自动切断创建和维护切线和垂直线,创建和维护满足相互几何关系的对象,识别和处理视觉交点(1202)以及3D中的对齐 空间。 本发明的其他技术包括自动识别感兴趣点(1310),使用屏幕消息来识别点(1201),使用次光标,创建临时几何,检查有趣点(1310) 这是由实际的几何形状,临时几何形状和/或实际和临时几何的相互作用产生的,精确的图形操作(例如绘图和变换)在有趣的点的帮助下(1310)。
