<b>Function</b>
<dd>
Converts a schematic into a board.

<b>Syntax</b>

<p>
The command BOARD is used to convert a schematic drawing into a board.
<p>
If the board already exists, it will be loaded into a board window.
<p>
If the board does not exist, you will be asked whether to create that new
board.
<p>
The BOARD command will never overwrite an existing board file. To create
a new board file if there is already a file with that name, you have to
<a href=78.htm>remove</a> that file first.
<p>
<u>Creating a board from a schematic</u>
<p>
The first time you edit a board the program checks if there is a
schematic with the same name in the same directory and gives you the
choice to create the board from that schematic.<br>
If you have opened a schematic window and want to create a board, just
type
<pre>
edit .brd
</pre>
in the editor window's command line.
<p>
All relevant data from the schematic file (name.sch) will be converted to a
board file (name.brd). The new board is loaded automatically as an empty
card with a size of 160x100mm
(<a href=327.htm>Light edition</a>: 100x80mm),
where the outlines are placed in such a way that the board is centered
between the 50mil grid.
All packages and connections are shown on the left side
of the board. Supply pins are already connected
(see <a href=69.htm>PIN</a> command).
<p>
If you need board outlines different to the ones that are generated
by default, simply delete the respective lines and use the
<a href=100.htm>WIRE</a> command to draw your own outlines into
the <i>Dimension</i> layer. The recommended width for these lines is 0.
<p>
A board file cannot be generated:
<ul>
<li>if there are gates in the schematic from a device
for which no package has been defined (error message: "device
name has no package). Exception: if there are only pins with
Direction "Sup" (supply symbols)
<li>if there are gates in the schematic from a device
for which not all pins have been assigned to related pads of a package
(error message: "device name has no connects"). Exception:
device without pins (e.g. frames)
</ul>
