Hi all,

For now, I'm quite ok with the 80mm x 100mm board size restriction in
the free 'Light' version of Eagle.

However, I might soon need to do bigger boards.

So a very simple idea hit me for how to do this in Eagle Light.

Assume we want boards up to 320 x 400 mm.

The obvious recipe would be:
- use an 80 x 100 board
- create a custom component library
- populate this library with all the components one uses
- edit the components' packages artwork, scaling them down to 1/4
of their size - pads, holes, the lot
- do 'Edit'/'Design Rules', and scale everything down to 1/4 of the
original values - trace widths, clearances etc
- in the board editor, scale the grid down to 1/4 the size
- if autorouting, scale the routing grid to 1/4 the size
- when printing out the artwork, scale it up to 4x the size

Rather time-consuming, but something I'm likely to try on a temporary
basis while I'm getting the money together to pay for Eagle Standard.
