voids, dynamic shapes, and 15.x

archive
archive over 17 years ago

Greetings all,

Pre-15.0, shape objects had an attribute of ->voids which contained a list of all the voids in the shape. A void consisted of a series of line/arc segments much like the parent shape.

Now in >15.0 I have a dynamic shape which contains several voids but the ->voids attribute shows nil  .
How can I access these voids using SKILL in 15.x ?

TIA,

    A dynamic shape is the boundary object that contains the original outline and any user added voids. A dynamic
    shape can contain 0 or more generated shapes. Generated shapes appear on class ETCH and contain the actual copper
    fills used for artwork.

    If you want to access the generated shape(s) of this dynamic shape then you should process the list of shapes on
    shapeAuto attribute [ dbid->shapeAuto ]. Each of these generated shapes may have zero or more voids.

    dbid->shapeAuto
    = nil then NOT a dynamic shape (basically any shape where dbid->shapeIsBoundary = nil)
    = () empty list, a dynamic shape with no etch
    = (dbid1, dbid2, ...) list of generated shapes


    By default axlSetFindFilter will always return the boundary shape. If you want the generated
    shapes do NOT add "BOUNDARY_SHAPES" to the list of ?enabled sent to axlSetFindFilter.
    Example: axlSetFindFilter(?enabled '("NOALL" "SHAPES") ?onButtons nil)
