Is there a way to get outer points of selected polygons?

kbhow

Hi,

Is there any SKILL codes which able to get the outer points of selected objects?

I was trying to create a new function which may required to get the outer points of selected objects (polygon/rectangle/instances and etc). I want to get a list of points where i can use it to create a polygon which cover all selected objects.

Example, let say i have selected 10 polygons, and i want a function to return me a list of outer points of my selected object. Can someone help?

Thanks

How

    Hello How,

    besides of the convex hull approach, my second proposal was to apply a
    upsizing-/downsizing-cycle to your shapes, did you already try if this fulfills your needs?

    si=geGetSelectedSet()
    cvid = geGetEditCellView()
    stmp=dbLayerSize(cvid "TMPLAYER" si 3.5)
    so=dbLayerSize(cvid "TGTLAYER" stmp -3.5)

    applying a suitable sizing instead of 3.5um will merge your
    shapes, even from more than one layer, into one shape;
    downsizing this shape by the same amount will result in
    a shape that should do what you want...

    kind regards
