Description
描述
此方法将捕捉一条线段、边或二者的延长线，从而创建出对应的垂线段。
This snap option will also find points on the extension of straight edges. Circular edges are always treated as full circles, if a circular edge is an arc the point that is found may not lie on the actual edge.
将线段的第二个端点捕捉至另一（黄色）线段的延长线上，借此令前者垂直于后者
如何使用
For general information about snapping see Draft Snap.
- 确定开启了
Draft ToggleSnap与
Snap Perpendicular。 - 选中底图线段工具进行绘制。先输入第一个端点。
- 将鼠标指针移至某线段或另一个对象的边上，下面来选取垂足（也就是确定线段的第二个端点）。
- 鼠标下的边将变为高亮黄色，且此边上有一个描述垂足的白色小圈；或者小圈位于目标边的延长线上，第二个端点将自动定位于两者的垂足。
- 点击鼠标将创建的第二个端点附于此处。
