Mark and Measure tool

Use the Mark & Measure tool to take measurements with centimetre precision in a site. Open it from the toolbar on the left side of the screen and its measurement tools with your saved measurements appear in a panel on the right.

Note: You can measure in the 3D view (panorama or point clouds) or the 2D map. Press Esc at any time to cancel a measurement. Measurements are saved automatically if you have the Save measurements role.

Measurement tools

Select a measurement type from Free, Horizontal, or Vertical. Then choose a mode within it based on requirements.

To view a measurement in 2D, use the secondary view in the bottom-right corner, or switch to the 2D map with the 3D / 2D toggle.

Settings

In the Mark & Measure panel, click the Settings icon to turn these options on or off:

• Magnifier: zoom in to place points more accurately (panorama view only).

• Auxiliary plane: show a fixed geometric reference for a surface area.

• Cursor coordinates: show the coordinates at the cursor's exact position.

• Measurement names: show the name of each measurement.

• Line segment distances: show side (segment) measurements.

• Switch coordinates: view cursor and point coordinates in different systems (site coordinates or a global spatial reference system), and include them when exporting.

Managing your measurements

Your measurements are listed in the panel. Click one to jump to it. From the list or directly in the view, you can:

• Hover over a measurement in the 2D or 3D view to colour, hide, or remove it.

• Share measurements or export them as PDF (see Share measurements).

• Download measurements as CSV or DXF (see Download measurements).

• Copy, paste, move, and rotate measurements.

• Drag and drop measurements into folders to group them.

You can create new measurements even when all existing measurements are hidden.

Measurement planes for polygon, rectangle, and circle measurements

Polygon, rectangle, and circle measurements are taken on a single plane. The number of points needed to define the plane depends on the mode:

• Free polygon: three points.

• Horizontal polygon: one point.

• Vertical polygon: two points.

• Horizontal or vertical rectangle: two points.

• Horizontal or vertical circle: two points.

Once the plane is defined, a dotted blue line shows the projection of the cursor onto that plane. This projection is used as a point in the measurement.

Take a free measurement

1. Select Free, then Distance, Polygon, Orthogonal, Point, or Polyline.

2. Left-click in the 3D view to place the start point. A blue line follows your cursor and shows the distance.

3. Complete the measurement:

   • Distance or Orthogonal: left-click the end point.

   • Polygon: return the cursor to the start point and left-click.

   • Point: left-click once.

   • Polyline: press Enter.

Note: To adjust a completed measurement, click one of its points and drag it to the location you want.

Take a horizontal or vertical measurement

1. Select Horizontal or Vertical, then Distance, Polygon, Rectangle, or Circle.

2. Left-click to place points. A blue line follows your cursor. For a rectangle, two parallel blue lines appear once you have placed the first two points.

Use the magnifier

The magnifier improves point-placement accuracy and works in the panorama view only.

1. Select a measurement mode.

2. In Settings, turn on Magnifier.

3. Place the start point, then move to the end point. The magnifier zooms in as you position each point.

Colour a measurement

1. Hover over a measurement and click the dropper icon.

2. Choose a colour.

Rename a measurement or folder and add a description

1. Double-click the current name (it highlights blue) and enter a new name.

2. To add a description, click the arrow to the right of the name and enter it.

Changes are saved automatically.

Group measurements

1. Click the folder icon to create a new folder.

2. Drag and drop measurements into the folder.

Share measurements

1. Select the measurements or folder using the checkboxes.

2. Click the Share icon. The selected measurements appear in the Export Measurements dialog, each with its name, distance, point location, a copyable link, and a screenshot.

3. Click Export as PDF.

Download measurements

Export measurements as CSV or DXF to support planning and data integration:

• CSV: removes manual transfer from PDFs to spreadsheets; useful for space management and site assessments.

• DXF: brings measurements into CAD applications as linework for modelling or site planning.

  With the measurement selected, click the Download icon.

• In the Export measurements screen, set the following:

  • File name.

  • Format: CSV or DXF.

  • Coordinate system: Site coordinate system (used when the site was created), Spatial reference system (chosen from the list), or Dataset (matches the dataset's system).

  • Delimiter (CSV only).

  • Number format (CSV only).

• Click Export to download the file.

Change the unit system

You cannot change your instance's unit system inside the Mark & Measure tool. In the topbar, open the Account menu, click Language & unit system, and select the option that suits you.

Permissions

Mark & Measure is available to Editors, Site Admins, and Global Admins by default. To grant access to another group (including the Everyone group for guest users), a Global Admin or Site Admin enables the Use measurement tool permission for that group under User Management > Groups. To let a group save measurements, enable the Save measurements role.
