You
can import 3D models in many file formats.
When you import a model, coordinates within a model are in model space (relative to the model origin). Coordinates in a project are in project space (relative to the origin in the center of the scene). The separation of model space and project space preserves the relative sizes of multiple models in the same project.
Also, when you import a project from any supported file format, Visualize automatically scales the scene to fit your model.
You can specify an option to automatically update models when the original file is updated and saved in the 3D software. If you specify this option, the application notifies you when models are externally updated, and you can accept or ignore the change. To specify this option, in the Import Settings dialog box, in the General section of the Geometry tab, select Monitor File.
