# How to manage pointclouds

###### Step 1 : Understand each pointclouds

Insert each scan by clicking on the purple **+** button in your ** Project files** layer panel (bottom left of your screen), then select the scans you want to view in your project and click **Add**.

Notice how some pointclouds will attach automatically, the automatic assembly will be successful if scans in adjacent rooms have enough points in common.

Select and move each one of them by selecting it and dragging it around your workspace area. 

| Pro tip! You can select each pointcloud by clicking on the iMapper target or by selecting the single scan in the **Project files** layer panel. Use the selection box by left clicking on your workspace and dragging your mouse over the pointclouds you want to select while holding the click.

###### Step 2: Viewing photos.

You can force the system to display the pictures of a specific pointcloud by selecting it. 

Click on the **Panorama ** icon at the top right of the screen to show / hide photos. Select a pointcloud to view only the photos related to the selected pointcloud.

###### Step 3: Manage pointclouds and groups

If the building is complex, you can rename each pointcloud with the room name to help in the next steps. To do that, use the **gear icon** beside the pointcloud name on the left part of the screen. You can also change the colour of the pointclouds for better contrast.

Create groups to manage multiple pointclouds, for example if more than one pointcloud belongs to the same floor or unit.
