Markup tools

The Markup toolbar can be found at the bottom of your screen. Markups can be used to either take measurements or mark up areas of interest on your project.

The different types of measurements provided by each tool are described in the sections below.

Point markups

The Point tool enables you measure the coordinates of a particular location or annotate a location, e.g. to highlight a point of interest for your colleagues.

How to use the Point tool

1. Select the point icon in the markup toolbar.

2. Navigate to the area of your project you would like to measure or annotate.

3. Single-click on your desired location to create a point markup.

4. Associated information, including the X, Y, Z coordinates will be saved as a post in the Scene manager.

5. The coordinates can be copied (e.g. to use outside of Sensat) using the Copy button:

Line markups

The Line tool enables you to measure the distance between selected points and to calculate the bearing* of a line. It also allows you to draw lines on your map, for example to highlight access routes.

How to use the Line tool

Select the line icon in the markup toolbar.
Navigate to the desired area of your project.
Single-click to create the first point of your line.
Move the cursor and single click again to create your second point and the first part of your line. If you want to create a multi-point line (polyline) repeat this action.
Double-click (or press enter) to create the final point and finish the Line markup.
Your measurement will be saved as a post in the Scene manager.
1. Both the 3D (point to point) Length and the 2D Horizontal (projected) length are reported for line markups in the 3D environment.
2. The Bearing* will only be reported for lines defined between two points. If a third point is added the bearing will not be reported.
To add a buffer to a 2D line markup, simply enter a value for the buffer width. This will generate a buffer of that width on either side of the line.
Note: Buffering is only available for 2D line markups.

* Bearing = the angle (in degrees) measured clockwise against North (North being 0°):

Zone markups

The Zone tool allows you to measure an area or to annotate an area of interest within your project site.

How to use the Zone tool

Select the zone icon in the markup toolbar.
Navigate to the area of your project that you want to measure or annotate.
Single-click to generate the first point.
Move the cursor and single click again to create the subsequent points of your polygon.
Double-click (or press enter) to create the final point and finish the Zone markup.
Your measurement will be saved as a post in the Scene manager.
1. Both the 3D Surface Area and the 2D (projected) Horizontal Area are reported for all zone markups:

Circle markups

The circle tool allows you to mark a circle around a centre point at a set radius in the 2D or 3D environment.

How to use the Circle tool

Select the Circle icon in the markup toolbar.
Navigate to the area of your project that you want to mark up.
Single-click to generate the centre point.
Move the cursor to the desired radius and double-click (or press enter) to create the circle. The elevation of the plane will match the elevation of the first point (vertex) that you created.
The new markup and its details will be saved in the Scene Manager.
If you want to edit circle after it's been created, click on anywhere on the markup to enter edit mode. You can then drag the centre point to reposition it, or adjust the radius by dragging the circle's edge.
To adjust the radius to a specific value, click the blue "Edit" link next to Radius in the Scene Manager. This will open a modal where you can enter the exact radius.

Cut and fill markups

The Cut-and-fill tool allows you to take a volumetric measurement, and reports the cut, fill and net (|cut| - |fill|) volumes for a selected area.

💡 Tip: use this tool for measuring stockpiles as part of earthworks management.

How to use the Cut-and-fill tool

Select the Cut-and-fill icon in the markup toolbar.
Navigate to the area of your project that you want to measure. 💡Tip: allow the pointcloud to fully load in the area that you are measuring to maximise accuracy.
Single-click to generate the first point.
Move the cursor and single click again to create the subsequent points of your polygon.
Double-click (or press enter) to create the final point and finish the Cut-and-fill markup. A flat level plane will be created. The elevation of the plane will match the elevation of the first point (vertex) that you created.
Once your markup has been created, a window will appear showing you the current elevation of the cut-and-fill plane. You have the option to proceed with this elevation (by selecting Set), or you can adjust it by using the arrows or by entering a new value. The cut, fill and net volumes will update as you change the elevation. Select Set to finalise your markup.
The new markup and its details will be saved as a post in the Scene manager.
If you want to edit the geometry of the markup after it's been created, simply click on the markup itself to enter the markup 'edit mode'.
If you want to edit the elevation of the markup after creation, click on the blue Edit link next to Elevation in the Scene Manager (see image below). This will reopen the window from step 6.

Height markups

The Height tool enables you to measure the perpendicular height between two selected points in the 3D environment.

It works by drawing a right-angled triangle, the elevation and vertical angles are also measured and reported.

How to use the Height tool

Select the Height icon in the markup toolbar.
Navigate to the desired area of your project.
Single-click at the base of the object that you're measuring to create your first point.
Move the cursor to the final height that you're measuring and double-click (or press enter) to finalise the measurement.
The perpendicular height as well as the elevation and vertical angles will be saved as a post in the Scene Manager.

Height profile markups

The Height profile tool enables you to measure a profile or cross-section of the pointcloud in the 3D environment.

How to use the Height profile tool

Select the Height profile icon in the markup toolbar.
Navigate to the area of your project that you want to measure. 💡Tip: allow the pointcloud to fully load in the area that you are measuring to maximise accuracy.
Single-click to select the first point in the height profile.
Move the cursor and single click again to create your second point and the first part of your line. If you want to create a multi-point line (polyline) repeat this action until you are done.
Double-click (or press enter) to create the final point and finish the height profile markup.
The distance and maximum elevation will be saved as a post in the Scene Manager.

The XYZ coordinates of the height profile can be downloaded as .CSV file by clicking on the "Download file (.CSV)" link below the graph.

Editing markups

How to add context to a markup

After you have created your markups, there are a variety of different ways you can add more context to a markup, you can:

change the name of markup.
change the colour and icon (this can be done for individual markups or in bulk).
add start and end dates so that it is linked to the timeline.
add a description.
add attachments.

Note: these actions are only available for markups you created or that have been shared with you. Learn more about workspace permission and content permissions.

How to edit the geometry of 2D (line and zone) markups

Click on the markup to enter the markup edit state. The markup will turn blue indicating that it can be edited.
Hover your cursor over the markup line or border. A blue dot will appear at the position of your cursor. Click on and drag this dot to create a new point (vertex).

How to edit the geometry of 3D markups

Line, Zone, Cut-and-Fill, Height and Height-profile markups

Click on the markup to enter the markup edit state.
To move an existing point (vertex):
1. Hover over the cone located at the point that you want to move until the cone turns white.
2. Click and drag on the cone to move it to a new location.
To create and move a new point:
1. Hover your cursor over the markup line or border. A new white cone will appear at the position of your cursor.
2. Click and drag this cone to create a new point at a new location.

Snapshot tool

The snapshot tool lets you capture high-resolution, distraction-free screenshots of your project by automatically hiding all menu bars. It's perfect for presentations, meetings, and collaboration.
