OK to have brd dimension NOT to start at origin, that is, (0,0)?

unebonnevie

Hi,

 

I have dilemma.  My brd design has to be 0.1 in. spacing, that is,

2.54mm spacing.  As you can see from the attached image, I can't have

the board dimension starts at the origin, the bottom left corner.  The

reason is that the red wires just under the green via would nearly touch

the bottom edge of the board, thus, violation DRC rules. If I move the

via up the next 0.1 in., then there is no DRC rule violation, but I have

a big gap now.  So, what I do now is moving origin, so that I won't have

a gap and still not having any DRC error.

 

As far as I know, that should be fine, correct?  At the end of the day,

it's the board's dimensions, regardless of its origin, is what counts?

 

Thanks

    You can make your board any reasonable size/shape you want and start it

    anywhere you need to (assuming you have the Pro version). The relative

    dinemsions between the components and pads will remain the same and on the

    grid regardless where you put your board outline. You can shift your board

    to allow for traces and to pass the DRC and it should be fine.

     

    Putting a corner at the origin is more for convenience than anything else.
