# Viewing and reviewing BIM models

You can select items in BIM models from the map and then view information about them and use them in other software functions, for example to perform a Cogo calculation, create a surface, or stake out.

To select an item from a BIM model, tap it in the map. The item you have selected is shown in blue. To select multiple items, press the Ctrl key on the controller and then tap the items in the map to select them. Depending on the enabled BIM model selection modes, you can select vertices, edges, curved edges (polyedges, such as the rim of a cylinder), or surfaces.

Items in a BIM file cannot be selected using Rectangle selection or Polygon selection.

Tap Review to view more information about the selected items.

When viewing a complex BIM model, the items you are most interested in may be hard to view because they are obscured by other objects, the model may not have well defined layers, or a layer may contain many items.

The tools in the BIM toolbar enable you to more easily isolate and view the data in the BIM model you are most interested in.

- Tap Selection mode to quickly disable or re-enable the selectability of item types when selecting items from a BIM model in the map.

  See BIM model selection mode.

- Tap Organizer to select items shown in the BIM model by Organizer group set up in Trimble Connect.

  See Selecting from BIM models by Organizer group.

- Tap Show only or Hide to filter items in the BIM model in the map.

  See Viewing and reviewing BIM models.

- Tap Property sets to download custom property sets applied to the BIM models shown in the map from Trimble Connect.

  See Reviewing custom property sets.

The BIM toolbar automatically appears next to the Map toolbar when at least one BIM model has at least one layer set to selectable in the map. If the BIM toolbar is not shown, tap on the Map toolbar and then select BIM toolbar.
