By default, your project has one view window called Standard. You can create additional view windows using the View Manager. Each view window can have different view settings. For example, you may want to keep the wireframe 2D plan view in the Standard view window, and create a new view window with a 3D view of the model.
When you create new view windows, you can switch between open view windows using the Window menu. You can also turn your view tabs on, which will display a row of tabs below the drawing area. This provides instant point-and-click access to all your view windows.
You can display multiple view windows at the same time using the Tile Open Views and Cascade Open Views tools. View windows can be moved, resized and closed to create the exact arrangement you want.
To access the View Manager:
Select View
> View Manager, or click the View Manager button on the Advanced
View Control toolbar.
