Starting the Schematic

If your design is a one-off, is just for you, and is never likely to be released for others to use, then you
can take the approach that we did in Chapter 2. However, you never know where a design might lead,
so it can be a good idea to design neatly.

When you look at other people’s schematic designs, you will often see the schematic itself
framed, with an information panel that provides useful information such as the name of the document,
the author, version, and other information such as the licensing of the design. The frame used in Figure
4-13 is the letter-sized frame from the Sparkfun-Aesthetics library and indicates that the design is
released under a creative commons license.

The frames can be added as if they were any other part. To add a frame, search the library for
“frame.” This will bring back frames of different sizes. The size “Letter” will be fine for small
designs; for bigger designs, “A3” is a better option. If a design grows unexpectedly, then you can
always replace the frame with a bigger one.

Place the frame with the bottom-left corner at the origin. Some of the details of the frame, such as
the document name and date last saved, will be automatically shown on the sheet. Note that for them
