3D View tools

The 3D view has a hidden toolbar in the top left corner containing different tools to work on the site data.

Information

This tool is selected by default. Its purpose is to select a data element and offer information about it. The selected element can be a point cloud or a vector feature.

Measurements

The measurement tool is located in the 3D View toolbar:

This tool has a Distance mode and an Area mode. To measure, the user must click on a point cloud to define a line or polygon. To finish the measurement, use a double click to add the last point, or push the "finish measurement" button or ESC key to keep the last confirmed point.

Some general notes about picking in Collage Web:

• The user can navigate (zoom, rotate, pan) while picking points, to get closer to the data or move to a different area without canceling editing.
• Notice the circle cursor. It shows the candidate point for picking.
• If the blue circle does not appear and you are unable to pick points, it may be because you are using a hybrid laptop or other touch enabled device. In that case, you need to disable the touch events.
• Be aware that points that are closer will get picked in preference to farther points. However, sometimes it is not clear if the candidate point is near or far. In that case, it may be helpful to get closer or rotate the camera to get a better view.

In the Distance mode, the tool will report the length of each segment on the 3D View, and the total length in the Measurement tool panel.

The units used to report these distances can be changed in the Preferences.

In the Area mode, the tool will report the total area, in the 3D View and the Measurement Tool panel. The units to report areas can be changed in the Preferences.

A button in the panel can be used to perform the area measurement in 2D, considering the area as flat.
