First person walk through mode is a powerful feature that enables you to ‘walk through’ a 3D model. This mode is mostly used for reviewing buildings, landscapes or other larger models that would require more than just rotation of a model to evaluate.
To turn this setting on, select the ‘First Person’ icon (person icon) in the toolbar across the bottom of the viewer pane.
Once you select the first person mode, you will be brought to an information menu that explains how to manipulate the model effectively. This can always be accessed by clicking the ‘i” information button in the top right of the viewer while in first person mode.
The navigation controls are as follows:
To exit first person mode and return to home in the model, click the first person button again and then the smaller home icon in the top right corner of the viewer.
