Building your own PCB component
Step 1: Build the component outline with line segments, arcs, text labels, or what ever primitive elements that the component may need. Silk outlines and surface mount pads
should be placed on the top layers. The component can be moved to bottom side of the board in a later step. Place pads of the appropriate type where the tracks are to
connect to the component. The numbers in light blue are the pin numbers displayed by the pad itself. They will not appear if the "Pin names/numbers" option is not
selected in the Setup Draw Modes.
Place 2 text strings that are &1 and &2. These will be used to display data after the component has been built. The &1 will be replaced by the reference
identifier and the &2 will be replaced by the type/value. There is an additional field that can be accessed be placing an &3. This will display the modifier field of the
Place any additional documentation that may be desired.
Step 4: Block the entire component setting the reference point of the block as the place that the component is to be grabbed from. The block can be as large as you desire
as long as it contains all of the elements of the component and nothing else.
Type <BB> or select Build Component from the Block menu.
