<div style="text-align: justify;">
Here are the steps:</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<b><i>Select the Components</i></b></div>
<div style="text-align: justify;">
Begin your layout by adding the components. Select the parts from the Component Manager dialog box. Many components (such as connectors) include Digi-key part numbers to make ordering easy.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<b><i>Position the Components</i></b></div>
<div style="text-align: justify;">
Drag each component to the desired location on your board. The Snap to grid feature makes it easy to neatly align the parts.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<b><i>Add the Traces</i></b></div>
<div style="text-align: justify;">
Now add each trace by clicking on the pin of a component and dragging the trace to another pin. If you link your schematic file to the PCB, then the ExpressPCB program highlights the pins that should be wired together in blue.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<b><i>Edit the Layout</i></b></div>
<div style="text-align: justify;">
Making changes is simple using standard commands such as Copy, Cut and Paste. Rearrange the parts by dragging them with the mouse. Traces always stay connected to their pins, even when you move things around. You can set the properties of items in your layout by double-clicking on them. For example, double-click on a trace to change its layer or width.</div>
