Toolbar ‣ Measure

The Measure tool is an interactive tool where you can drag lines in the scene to measure distances or angles. Snapping to geometry could be activated for better accuracy or to measure wall thickness. The Measure tool can be accessed from the Toolbar.

Examples of the Measure tool.

Usage

Here are some common steps for using the Measure tool:

  1. Activate the Measure tool from the Toolbar.

  2. Click and drag in the viewport to define the initial start and end point for the ruler. You can add multiple rulers in the viewport.

  3. Click on either end of the ruler to select it and move the endpoints.

    • Holding Ctrl while moving enables snap to edges and vertices. A small circle appears when the end point is snapped to a vertex or edge. This way you can place the endpoints more accurately.

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

    You can always navigate (pan, zoom, …) or change the view (orthogonal, perspective) in the viewport to have better access to the ruler.

  4. Click on the midpoint of a created ruler to convert it to a protractor. Move this midpoint to set the vertex of the angle. Holding down Ctrl enables snap to edges and vertices. Move the endpoints to change the angle size.

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

All measurements are hidden when another tool is selected. They are shown when the Measure tool is selected again. Yet you can do editing operations while the ruler is active. For example, you can edit the rotation or dimension of the selected object in the Sidebar. The measurement values do not appear in the Render output.

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

Tipp

In Edit Mode only, there is also a Measurement setting in the Viewport Overlays popover. Edge length, edge angle, face area and face angle can be displayed through this setting.
