PCB Outline

ivy372

Hi guys,

I have write a skill that change origin to low-left of the PCB  board.

But how can I change the origin to the Board outline center point?

-----------------------------------------------------------------------------

axlCmdRegister( "o_ll" 'o_ll ?cmdType "interactive")
(procedure o_ll()
axlExtentDB()
x = -( caar( axlExtentDB()))
y = -( cadar( axlExtentDB()))
axlDBChangeDesignOrigin( x:y )
axlUIConfirm( "Change Origin to LowLeft.")
)

------------------------------------------------------------------------------

Thanks~

    Try something like this:

    outlineShp = car(axlDBGetShapes("BOARD GEOMETRY/DESIGN_OUTLINE")) || car(axlDBGetShapes("BOARD GEOMETRY/OUTLINE"))
    if(outlineShp then
    centrePt = axlMidPointLine(outlineShp ->bBox)
    else
    axlClearSelSet()
    axlSetFindFilter(?enabled '("noall", "invisible", "lines"), ?onButtons '("noall", "lines"))
    axlAddSelectAll()
    outlines = setof(obj, axlGetSelSet(), obj ->layer == "BOARD GEOMETRY/OUTLINE")
    xMin = min(caar(car(outlines) ->bBox), caadr(car(outlines) ->bBox))
    yMin = min(cadar(car(outlines) ->bBox), cadadr(car(outlines) ->bBox))
    xMax = max(caar(car(outlines) ->bBox), caadr(car(outlines) ->bBox))
    yMax = max(cadar(car(outlines) ->bBox), cadadr(car(outlines) ->bBox))
    foreach(line, cdr(outlines)
    xMin = min(caar(line ->bBox), caadr(line ->bBox), xMin)
    yMin = min(cadar(line ->bBox), cadadr(line ->bBox), yMin)
    xMax = max(caar(line ->bBox), caadr(line ->bBox), xMax)
    yMax = max(cadar(line ->bBox), cadadr(line ->bBox), yMax)
    )
    centrePt = axlMidPointLine(list(list(xMin, yMin), list(xMax, yMax)))
    )
    axlDBChangeDesignOrigin(axlMXYSub(0:0, centrePt))

    Hi eDave,

    Thanks very much~

    But I want to change the origin to the low-left of PCB Board.

    I hope the origin set on the middle line of BOARD GEOMETRY/OUTLINE.

    like below:

    axlClearSelSet()
    axlSetFindFilter(?enabled '("noall", "invisible", "linesegs"), ?onButtons '("noall", "linesegs"))
    axlAddSelectAll()
    outlineSegments = setof(obj, axlGetSelSet(), obj ->layer == "BOARD GEOMETRY/OUTLINE")
    axlClearSelSet()
    minx = min(apply('min, mapcar('caar, outlineSegments ~>startEnd)), apply('min, mapcar('caadr, outlineSegments ~>startEnd)))
    miny = min(apply('min, mapcar('cadar, outlineSegments ~>startEnd)), apply('min, mapcar('cadadr, outlineSegments ~>startEnd)))
    axlDBChangeDesignOrigin(axlMXYSub(0:0, minx:miny))

    Hi eDave,

    Can you please explain me how to execute this code.
