Reducing dimension of a single sided board

[seangiffney]

I am a complete beginner with Eagle.

I have spent hours over several days learning by trial and error, and watching the tutorial videos.

I have drawn a very simple schematic in Eagle, and converted it to a board.

I worked out how create a '.dxf' file, which I can use with a CNC mill to create a single sided pcb from some blank sheet.

The problem I have is the board has dimensions larger than I was hoping for, and although the .dxf file I have created will work with the CNC mill (and blank copper/fibreglass sheet) it is too large for the enclosures I need it to fit.

Is there anyway I can scale the board down in size, the only 'components' I have placed are "pads".

This is a through-hole build and very simple, I have been drawing this by hand and etching the boards up until now, which is what I look like going back to if this software is too hard to use, or not capable of making the task easier.

I think I may have just wasted a week that I could have used drawing the boards by hand and etching them.

Regards.

Absolutely there is!

I assume you just have the default 100mm x 80mm outline as defined when you first create a board. All you need to do is use the MOVE tool to move the upper and right hand vertices on the dimension layer to adjust the board size as needed, or delete the current outline and redraw in as necessary with the WIRE tool. One thing to note, I assume you are using the free license so make sure the bottom left most corner of your PCB is sat exactly on the 0,0 origin of the board working area otherwise you may end up with issues moving/placing parts.

Best Regards,
