Mouse Controls

In the 3D PCB Viewer, the display is controlled through the following mouse actions when the cursor is in the view window:

• Dragging the mouse with the left button depressed causes the image to rotate.

• Dragging the mouse with the middle button depressed causes the image to pan.

• Dragging the mouse up with the right button depressed causes the image to zoom out, while dragging it down causes the image to zoom in.

• Simultaneously holding down the Shift key and the left mouse button while dragging the mouse lets you select a specific area.

• Simultaneously holding down the Shift key and the middle mouse button while dragging the mouse lets you select and zoom in on a specific area.

Figure 2-2 lists the mouse controls that are available when the cursor is in the View window.

When the Fly Around feature is selected, the movement initiated by the mouse button continues after you release the mouse button.

Removing the cursor from the View window always stops the rotation, panning, or zooming of the image, as will pressing any of the mouse buttons.

When the cursor is in the Display Control window, the mouse controls are as follows:

• Clicking on a component icon in the Display Control Assembly tab selects and highlights the component in the 3D View window. Selecting another component unselects any previously selected component.

• Clicking where there is no component clears all selections.

• Holding down the left mouse button while dragging the cursor will select a range of components.

• Holding down the Shift while clicking on component selects it while retaining previous selections.

• Middle mouse button scrolling zooms in and out.

When the cursor is in a drop-down list box, the left mouse button opens the list so you can make a selection, whereas scrolling the middle mouse button cycles through the selections in the list.
