描述

底图三圆周点绘弧工具通过输入4个点：中点、半径、第一个点、最后一点，或拾取的切线，或上述若干组合，在当前的工作平面上创建一条圆弧。它将根据Draft Tray中的Draft Linestyle设置来创建对应圆弧。

Use the Draft Arc tool to create a circular arc by specifying the center, the radius, and the start and end angles. To draw an elliptical arc use Draft Ellipse. You can also approximate a circular arc by using the Draft BSpline, Draft BezCurve, and Draft CubicBezCurve tools.

根据圆周上的3个点而定义的弧

如何使用

  1. 按下 Draft Arc 3Points按钮，或先按A键再按T键。
  2. 在3D视图中点击第一个点，或输入一个 坐标并按下 add point按钮。
  3. 在3D视图中点击第二个点，或输入一个半径值。
  4. 在3D视图中点击第三个点，或输入一个起始角度。

选项

  • Press X, Y or Z after one point to constrain the following point on the given axis.
  • To enter coordinates manually, simply enter the numbers, then press Enter between each X, Y and Z component.
    • You can press the add point button when you have entered the desired values to insert the point.
  • Press R or click the checkbox to toggle relative mode. If relative mode is on, the coordinates of the following point are relative to the previous one; if not, they are absolute, taken from the origin (0, 0, 0).
  • Hold Shift while drawing to constrain your next point horizontally or vertically in relation to the previous one.
  • Press Esc or the Close button to abort the current command.

属性

属性

弧对象享有Draft Circle中的所有属性，但是有些属性仅对圆形而言才有意义。

There is no specific function to create an arc by three points.

To create an arc use the same function to create circles, with additional arguments. See the information in Draft Arc and Draft Circle.
