Measurement

The Model Editor has built-in measurement tools for reading coordinates, distances, and areas in model space.

Note: Measurement data is kept only while the editor is open. Closing it clears the measurement history.

Measurement Types

Coordinate

Reads the absolute coordinate (X, Y, Z) of a point in the scene.

How to use: Click "Coordinates" in the toolbar → click a target point on the model surface → the values appear

Note: Before using Coordinates, the system checks that every model in the scene has RTK data. All models need RTK data for this to work.

Distance

Measures the straight-line distance between two points.

How to use:

1. Click "Distance"
2. Click the first point
3. Move the cursor; the distance updates in real time
4. Click the second point to finish

Area

Measures the area of a closed polygon region.

How to use:

1. Click "Area"
2. Click points in order (at least 3)
3. Click the start point to close, or double-click to finish

Note: The result shows only the area; hovering over a segment shows that segment's length.

Snapping Aids

Surface snapping

When measurement is on, the cursor becomes a crosshair with a patch that snaps to the model surface. On by default.

Use case: Keeps measurement points precisely on the model surface, avoiding stray clicks in empty space.

Drag to adjust

Distance and area measurements let you drag an existing point to reposition it; the result updates in real time.

Use case: When a point isn't precise enough, drag to fine-tune instead of remeasuring.

Delete a Measurement

Hover over a result; a delete icon appears below it. Click to delete that measurement.
