# Files in the Scene

This article explains how and where several parts of architectural models can be joined and walked in one scene. This is especially helpful when plans from different construction companies flow together, when electricity and ventilation plans have been created separately or when an environment is to be added in addition to the model.

1. In order to merge several files into one scene, one of the files must first be uploaded. Then open this scene and switch from the "3D view" tab at the top to "Files in the Scene". Here you see an overview of the individual files that are in a scene. 
2. Behind each file, adjustments can be made under the settings icon. You can choose between Delete, Replace and Reprocess.
3. Additional files can be added to the existing scene by clicking on the plus symbol.
