Hallo everyone, i am trying to remove the overlapping or intersected imported family with the linked elements, i tried to the bounding box method but it didnt work, both overlapps as well in the 3d is there any method that could help to get that. thank you so much.
this was my try of finding the intersected grid with linkedElements :
"
private bool FamilyInstanceOverlaps(FamilyInstance instance, List<Element> linkedElements)
{
BoundingBoxXYZ bb = instance.get_BoundingBox(null);
if (bb == null)
{
return false;
}
Outline outline = new Outline(bb.Min, bb.Max);
BoundingBoxIntersectsFilter intersectsFilter = new BoundingBoxIntersectsFilter(outline);
foreach (var element in linkedElements)
{
BoundingBoxXYZ elementBox = element.get_BoundingBox(null);
if (elementBox != null && BoundingBoxIntersects(bb, elementBox))
{
return true;
}
}
return false;
}

}
this is what i am willing to get
3d view
