These are the navigation features only present in the 2D view:

Zoom rectangle

With the Zoom Rectangle tool you can enlarge a selection of a 2D drawing area. The zoom rectangle is useful when you want to zoom in on a very small detail. This feature is accessed from the toolbar above the 2D view. It is also found in the context menu when you right-click in the 2D view.

To use this tool, follow these steps:

1. Click Zoom Rectangle.
2. Move the mouse pointer to the drawing area. A small, light blue rectangle follows.
3. Click-and-drag the mouse button to draw a rectangle over the area you want to enlarge.
4. Release the mouse button.
5. The 2D view now shows the area inside the rectangle you drew. Repeat this procedure to obtain detailed close-ups.
6. Once you are finished, hit Esc on your keyboard, or move your cursor outside of the drawing area to escape the command.

Zoom to New View

With the Zoom to New View tool you can select an area in the drawing area which will display in a popup window. 

With this feature you can easily change a small detail in a drawing while you simultaneously get a general view of the whole drawing.

To zoom to a new view, follow the steps below:

1. Click the Zoom to New View tool.
2. Move the mouse pointer to the drawing area. A blue rectangle follows.
3. Click-and-drag the mouse button to draw a rectangle over the area you want to send to the New View.
4. Release the mouse button. A the area selected appears in a popup window.
5. This New View, or popup view, functions the same as a regular drawing view, and can be toggled between 2D, 3D, or Paper View. The New View is in a separate window which can be moved onto a new screen.
