测量 工具是一种交互式工具，您可以在场景中拖动直线以测量距离或角度。可以激活吸附到几何图形以提高准确性或来测量壁厚。测量 工具可以从工具栏访问。

测量工具的示例。

用法

以下是使用 测量 工具的常用步骤：

1. 从工具栏激活 测量 工具。

2. 在视图中点击并拖动以定义标尺的初始起点和结束点。可以在视图中添加多个标尺。

3. Drag either end of the ruler to move it.

   • Holding Ctrl while moving enables snapping to edges and vertices.

   • Holding Shift while moving lets you measure the distance between faces. This only works well with parallel faces, e.g. walls.

   您可以始终在视图中导航（平移，缩放，…）或更改视图（正交，透视）以更好地访问标尺。

4. Click on the midpoint of a created ruler to convert it to a protractor. The midpoint can then be dragged just like the endpoints.

5. A selected ruler can be deleted with Delete or X. To delete all measurements, delete the "RulerData3D" layer in the Sidebar ‣ View ‣ Annotations panel (see image above).

All measurements are hidden when another tool is selected. They are shown when the Measure tool is selected again. However, you can do editing operations while the ruler is active. For example, you can edit the rotation or scale of the selected object in the Sidebar.

Measurements do not appear in the Render output.

Unit settings and scale from the scene are used for displaying dimensions. Changing the unit system (metric, imperial), or the units of length (cm, m, ...) or angle (degrees, radians) will update the measurements.

Tip

In Edit Mode only, there is also a Measurement group in the Viewport Overlays popover. Using the settings in this group, you can have the viewport automatically display measurements for selected edges and faces, without the need to manually create a ruler.
