描述

此工具会根据用户在3D视图中拾取的两个点来绘制一条线。在开启此工具时，鼠标指针会变为具有一个红色线条图标的白色十字。侧面还会实时显示当前指针的坐标。

如何使用

从3d视图中的某个空白区域或从一个已存在的对象上（一定要激活TaskView中的自动约束（auto constraints。译注：0.18版中自动约束设置位于底图的首选项中））拾取两点。
按Esc键或点击鼠标右键退出此功能。

+<span id="Usage"></span>
-此工具创建的线条对象的首尾都位于用户指定的对应点处，但是对于[[Sketcher ConstrainTangent|切线（Tangent）]], [[Sketcher ConstrainPointOnObject|对象上的点（Point On Object）]]与[[Sketcher_ConstrainAngle|内角（Internal Angle）]]约束而言，此线条却是无限长的。
+<div class="mw-translate-fuzzy">
-这就意味着，例如，有着[[Sketcher ConstrainPointOnObject|对象上的点（Point On Object）]]约束的点可能并不位于用户指定的两点之间，但是却可能位于两点所绘线段的延长线上。
