Can anyone help me to get via on a single net if it is inside the BGA premises. Thanks.
You can use axlGeoPointInShape as advised by eDave but you ca also use axlIsPointInsideBox as alternative if you do not have the datebase id of the BGA placebound.
point = viaDbid->xy
box = BGAsymbolDbid->bBox
ptIsInsideBGA = axlIsPointInsideBox(pt box)
output will be t/nil
Hope it helps.
