6. Exploring viewing and manipulation options for an OBJ file

Once we have imported the OBJ file into our 3D modeling application or software, it is important to know the viewing and manipulation options that are available to us. These options allow us to see the model at different angles and scales, as well as make changes or modifications to its structure.

One of the most common display options is the ability to rotate the model in different directions. This allows us to examine it from all possible angles and appreciate the details of its design. To rotate the model, we can use drag and drop functions, or use the rotation controls available in the software.

Another very useful option is the ability to zoom in or out of the model. This allows us to examine it in detail or have an overview of it. To do this, we can usually use the zoom controls or the mouse wheel. It is also possible to adjust the perspective of the view to have a more realistic or flatter view of the model.
