Measure Angle shows the angle between points, mesh edges or features that you click on a model. Use it to check the angle between two faces of a part, the slope of a wall or the angle of a chamfer.
Measure an angle by three points
- Select the object in the Scene Tree.
- Click Inspect › Measure Angle.
- Click three points on the model. The second point is the vertex of the angle: click a point on the first side, then the corner, then a point on the second side.
The panel shows the Angle and the X, Y and Z coordinates of Point 1, Point 2 and Point 3. The viewport shows the arc and the value at the corner.
Each clicked point is listed under Measuring angle between with a Reset button. Click Reset next to a point to remove it and click a new one. After the third point the angle is complete; the next click starts a new angle.
Measure between edges or features
- Use mesh edge: turn it on (or hold Shift+Alt, Shift+Option on macOS) to click mesh edges instead of points. The angle is measured between the two edges. This works on meshes only.
- Features: click two features, for example two planes fitted to the faces of a scanned part with Inspect › Plane. This is the reliable way to measure a scan, where single points are noisy. See How to create and measure features.
- Cone angle: click a cone feature, then click the same cone again to measure the angle of the cone.
The Subfeatures section lists the reference points and lines of the clicked features, for example the axis of a cylinder. Click one to measure from it.
Options
| Option | What it does | Default |
|---|---|---|
| Add to Scene | Each finished angle stays in the scene, in the Dimensions folder under the object in the Scene Tree. When it is off, each new angle replaces the previous one. | On |
| Chain measurements | The next angle reuses the end of the previous one: for an angle of three points it keeps the last two, so after A–B–C one more click D gives the angle B–C–D. Hold Ctrl (Cmd on macOS) for one measurement. | Off |
| Snap to vertex | Each point jumps to the nearest mesh vertex, for example to an exact corner. Hold Shift for one point. | Off |
| Snap to edge | Each point jumps to the nearest mesh edge. | Off |
| Use mesh edge | Click mesh edges instead of points. | Off |
| Place point on the surface of a feature | The point is placed on the surface of a feature instead of using the feature as a whole. Hold Alt (Option on macOS) for one point. | Off |
Holding the key turns the option the other way while you hold it.
Next to the result:
- Adjacent switches to the adjacent angle formed by the same references and updates the arc and the value.
- Copy to Scene keeps the current angle in the scene when Add to Scene is off.
To measure a distance instead of an angle, use Measure Distance.
