Object Tree
You can use the object tree to manage the visibility of the building model. The tree presents all building objects categorized in a hierarchical order. When you open a project, the object tree is opened with the document browser on the left side of the workspace. Set the object tree visible by selecting the browser tab Model.
You select objects in the tree in a variety of ways: all objects on the same floor, all objects of a certain type on the same floor, individual objects, etc. You can hide and restore objects or select other functions in the context-sensitive menu.
If you have access to the Rendering additional feature, you can edit the lights, background and foreground of the model in the object tree.
