Buenos dias!!
Estoy con dificuldade de entender o que me cita,
Estoy seguindo tambíen las intruciones del manual, mas não consigo definir una area diferente. Estoy anexando una imagem explicando mi dificuldade.. fiz outro quadro con layer Dimension, mas não consigo mover los componentes dentro de todo quadro.
Tieno que aplicar alguno comando to comit the changes?

El manual diz:
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 (Light edition: 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 PIN command).
If you need board outlines different to the ones that are generated by default, simply delete the respective lines and use the WIRE command to draw your own outlines into the Dimension layer. The recommended width for these lines is 0.
Saludos,
Alexandre.
