Clips define an area of interest within a project and hide data that is outside of that area of interest. Clips are useful for navigation, visualization and analysis as they allow the user to home in on important details without subdividing a project or deleting data.
In addition to accessing Saved Clips, users can create new Clip Boxes which will persist through the duration of TruView session but cannot be saved to the project.
Both point clouds and Models will adhere to the Clip Box.
Creating a Clip Box:
Click on the Manually Create Clip Box button.
Select one of the three Clip Box creation options.
Manually Create Clip Box
A Clip Box will be created at the entire extent of the project. At this point the Clip Box can be manually adjusted to an appropriate size.
Create Clip Box by Size
Define a Clip Box size, then identify a point in the viewer. The Clip Box will be created at the defined size using the selected point as the centroid.
Once a Clip Box is created, several controls will open that can be used to manipulate the clip box with a mouse or on a touch screen.
Users may also click on a cube face and drag it to change the size of the box.

It is possible to create a time clip and a clip box in the same project. It is not possible to create more than 1 time clip or clip box in the same project.
Temporary Clips do not get saved into the project. They will only exist during the current session.
