Scale & Zoom

Use the zoom tools to modify the scale of the diagram, either via the editable list box „Scale 1:“ on the symbol bar, or via the three global tools in the toolbox:

Zoom +

Zoom -

Zoom to Limits

Using a mouse with mouse wheel this can be used alternatively to change the scale.

Combo Box "Scale 1:“

By clicking the arrow to the right of the box „Scale 1:“ on the icon bar, a list of predefined scales drops down. You may click the desired scale on that list. The graphic on the CadnaA main window will be modified accordingly-

Combobox

You may also enter an arbitrary scale. Click the edit box and enter the desired value. Then press RETURN.

Zoom in

The "Zoom +" icon on the toolbox allows you to enlarge the graphic representation of a specific area. After clicking this icon, the mouse pointer drags along a little magnifier icon with a "+" sign.

There are two comfortable ways of enlarging a selected area:

  1. Clicking an object with the left mouse button enlarges the graphic by a factor of two with each click. The position of the mouse pointer becomes the new centre of the displayed area.

  2. If you hold the left mouse button down, you can draw a rectangle around the objects you wish to enlarge. Upon releasing the mouse button, the area within the rectangle will be enlarged so as to fill the screen.

The enlarging is undone in reverse order by clicking with the right mouse button.

Zoom out

The "Zoom -" icon on the toolbox allows you to reduce the graphic representation of a specific area. After clicking this icon, the mouse pointer drags along a little magnifier icon with a "-" sign.

Clicking an object with the left mouse button reduces its size by a factor of two. You may repeat this several times. The reducing is undone in reverse order by clicking with the right mouse button.

Zoom to Limits

All objects lying outside the visible area will immediately be shown on the CadnaA main window when you click this icon. The scale of the representation is automatically selected according to the dimensions of the limits and the size of the CadnaA main window.
