Collect detail items inside crop region

[mr.engineer.aec]

 Hi mate,

 I have many detail items outside crop region.

 But i only want to select detail items inside crop region.

 I use code like this but it collect both inside and outside detail items.

 What can i do ?

 Thank in advanced !

            List<FamilyInstance> symbols = new FilteredElementCollector(doc, doc.ActiveView.Id)
                .OfClass(typeof(FamilyInstance))
                .WhereElementIsNotElementType()
                .Where(x => x.Category.Name == "Detail Items")
                .Where(x => x.IsHidden(doc.ActiveView) == false)
                .Cast<FamilyInstance>()
                .ToList();

Hi @mr.engineer.aec ,

One solution is to get the bounding box from the crop box and create a BoundingBoxIntersectsFilter.

if(doc.ActiveView.CropBoxVisible && doc.ActiveView.CropBoxActive)
                  {
                      BoundingBoxXYZ bb = doc.ActiveView.CropBox;
                      Outline myOutLn = new Outline(bb.Min, bb.Max);
                      BoundingBoxIntersectsFilter filter = new BoundingBoxIntersectsFilter(myOutLn);                    
                  } 

Now use this BoundingBoxIntersectsFilter along with other filters in FilteredElementCollector to get the required elements.

Could you please try this suggestion and let me know?

 Thank @naveen.kumar.t for reply,

 I think if use boundingbox it'll collect detail items like this so,

 I want to collect only inside mate.

Hi @mr.engineer.aec ,

Could you please try using BoundingBoxIsInsideFilter.
