I WANTED CREATE VOID ON HOLES AS USING MY CODE ITS REMOVING THE SHAPE DBID

Henry Monro

Hello,

I have developed the below code and on running it is removing the Shape DBID after first void creation as shown in snap below.

I would be thankful If anyone can help in this regard and provide a better way for void creation on multiple holes.

Thanks

    Hello Henrt

    I am having issue with running this code, can you provide complete code to test it at my end?

    This might help:

    Note that you need to open the shape after all the other processing of the shape.

    defun( monro (airgap, net_name, void_size)
    l_layers_visible = '("ETCH/TOP")
    net_name = upperCase(net_name)
    antipad_half=void_size/2.0
    axlSetFindFilter(?enabled list("noall") ?onButtons list("noall"))
    axlSetFindFilter(?enabled list("VIAS" "SHAPES") ?onButtons list("VIAS" "SHAPES"))
    axlSelect()
    l_vias = setof(obj, axlGetSelSet(), obj ->objType == "via" && obj ->net ->name == net_name)
    l_shapes = setof(obj, axlGetSelSet(), obj ->objType == "shape" && memv(obj ->layer, l_layers_visible))
    axlClearSelSet()
    foreach(shape, l_shapes
    l_poly_shape = axlPolyFromDB(shape)
    voidPolys = nil
    foreach(via, l_vias
    list_shape_layer = unique(setof(obj, axlDBGetConnect(via t), obj ->objType == "shape") ~>layer)
    l_airgap = axlAirGap(via, shape, shape ->layer, 'enhanced)
    airgapsize = l_airgap ->airGap || 0.0
    when(!memv(car(l_layers_visible) list_shape_layer) && airgapsize < airgap
    l_location=list(via->xy, antipad_half)
    rpath = axlPathStartCircle(l_location, 0.0)
    poly_circle = car(axlPolyFromDB(rpath))
    voidPolys = cons(poly_circle, voidPolys)
    )
    )
    openShape = axlDBOpenShape(shape->shapeBoundary)
    foreach(poly, voidPolys
    axlDBCreateVoid(openShape, poly)
    )
    shape = car(axlDBCreateCloseShape(openShape))
    axlShapeDynamicUpdate(shape t)
    )

    Hi !

    try this code

    (defun for_cut_voidshape ()
    airgap = "5";axlFormGetField(form "airgap")
    net_name = "VSS"; axlFormGetField(form "net_name")

    airgap = atoi(airgap)
    net_name = upperCase(net_name)
    void_size = atoi(void_size)
    antipad_half = void_size/2
    axlSetFindFilter(?enabled '(noall VIAS SHAPES NAMEFORM) ?onButtons '(noall ALL))
    axlSelect()
    l_shapes = setof(e axlGetSelSet() e->objType =="shape")
    l_vias = setof(e axlGetSelSet() e->objType =="via")
    axlClearSelSet()
    temp_list = nil
    foreach(via,l_vias
    foreach(shape, setof(e l_shapes e->net == via->net)
    tmp = shape->segments
    foreach(void shape->voids
    foreach(seg void->segments
    tmp = cons(seg tmp)
    )
    )
    foreach(seg tmp
    gap = axlAirGap(via seg seg->layer)
    if(gap != nil && caddr(gap) < airgap || gap == nil then
    d = axlMXYAdd( 0 : antipad_half via->xy)
    r_path = axlMakeDynamicsPath(list(list(d d 0.0 via->xy antipad_half t) list(d d) ) )
    poly = car(axlPolyFromDB(r_path ?layer shape->layer ?endCapType 'ROUND))
    if(member(poly temp_list) == nil then
    temp_list = cons(poly temp_list)
    )
    )
    )
    )
    )
    foreach(poly temp_list
    axlClearSelSet()
    axlSetFindFilter(?enabled '(noall SHAPES NAMEFORM) ?onButtons '(noall ALL))
    axlSingleSelectBox(poly->bBox)
    shape = car(axlGetSelSet())
    openShape = axlDBOpenShape(shape->shapeBoundary)
    axlDBCreateVoid(openShape, poly)
    axlDBCreateCloseShape(openShape)
    )
