3D Maya Question:

The user interface is nothing but how you can control Maya. Initially, it will be like an application for image editing. But, it is more complex and there are multiple features that cannot be seen in various apps. Initially, you might be beset by user interface of Maya but later you will get used to that software. Drop down box in status bar is adjusted to change menu bar. It will be same as some other application for windows. Selection of tools can be done using the tool box that you are interested in developing 3D models. Also, it is possible to develop multiple layers similar to Photoshop.
