Object Snap Tracking 对象捕捉追踪

 

Object snap tracking works in conjunction with object snaps

对象捕抓追踪与对象捕抓连接起来，一起工作

After acquire a point, horizontal, vertical, or polar alignment paths relative to the point are displayed as you move the cursor over their drawing paths.

从对象捕捉点沿着垂直对齐路径和水平对齐路径追踪光标

Home tab > Draw panel > Circle - Center, Radius

默认选项卡 > 绘画面板 > 园 - 圆心，半径

Pick a center point

拾取中心点

Acquire a point from right view to get the radius of circle

从右视图捕获一点作为半径

Move back to center until the horizontal and vertical alignment path meet each other perpendicularly, then pick a point.

光标移回中心点直到水平与垂直对齐路径交叉成十字后拾取一点

Home tab > Draw panel > Arc - Center, Start, End

默认选项卡 > 绘画面板 > 圆弧 - 圆心，起点，端点

Pick a center point from the circle

自园拾取中心点

Acquire a point from top view for the start point

自平面图捕获一点作为起点

Acquire another point from top view for the end point

Rotate cursor 180 degrees to left

An arc created based on the points from the top view

光标旋转180度至左边

圆弧形成基于捕获端点自平面图

Home tab > Draw panel > Line

默认选项卡 > 绘画面板 > 直线

Acquire a point from the top view

自平面图捕获一点

Acquire a point from the right view

自右视图捕获一点

Acquire a point from the top view

自平面图捕获一点

Intersect to the center line

交叉至中心线

Join to the starting point

连接至圆弧的起点

Front view is created by acquire points from right and top view

通过捕获端点自平面图与右视图完成正视图
