Hello guys , is there a way to extract the rooms(from a linked document) that are visible in a host view project? i tried doing the bounding box intersection but as you can see the bounding box of the selected view is very far away from the rooms bounding boxes because of using scopeboxes, any other way?

Check whether your LinkInstance has a transformation (it’s likely that your architectural model isn’t linked origin-to-origin); if so, you must account for this transformation in your code to correctly reposition the Room Solids or Room bounding boxes.

Try using the OOTB node LinkInstance.AllElementsOfCategory. [image] Try this python option import clr clr.AddReference("RevitServices") from RevitServices.Persistence import DocumentManager clr.AddReference("RevitAPI") from Autodesk.Revit.DB import * from Autodesk.Revit.DB.Architecture import Room def is_room_type(elem): return isinstance(elem, Room) doc = DocumentManager.Instance.CurrentDBDocument # Get link document with room by keyword in filename - NOTE: Case Sensitive bip = ElementId(BuiltInParameter.ELEM_TYPE_PARAM) pfrf = ParameterFilterRuleFactory.CreateContainsRule(bip, "Architect") epf = ElementParameterFilter(pfrf) link_instance = ( FilteredElementCollector(doc) .OfClass(RevitLinkInstance) .WherePasses(epf) .FirstElement() ) link_doc = link_instance.GetLinkDocument() # Bounding Box Filter crop_box = doc.ActiveView.CropBox outline = Outline(crop_box.Min, crop_box.Max) bb_inside = BoundingBoxIsInsideFilter(outline) bb_intersects = BoundingBoxIntersectsFilter(outline) # SpatialElement works with the primary DB and is recommended rooms_inside = ( FilteredElementCollector(link_doc) .OfClass(SpatialElement) .WherePasses(bb_inside) .ToElements() ) rooms_intersects = ( FilteredElementCollector(link_doc) .OfClass(SpatialElement) .WherePasses(bb_intersects) .ToElements() ) OUT = filter(is_room_type, rooms_inside), filter(is_room_type, rooms_intersects)

FilteredElementCollector Class If you are using rvt 24 or above, you can stop doing things the hard way since FilteredElementCollector now accepts a linkId.

:exploding_head: Using a category filter is neater as well import clr clr.AddReference("RevitAPI") from Autodesk.Revit.DB import ( BuiltInCategory, BuiltInParameter, ElementId, ElementParameterFilter, FilteredElementCollector, ParameterFilterRuleFactory, ) clr.AddReference("RevitServices") from RevitServices.Persistence import DocumentManager doc = DocumentManager.Instance.CurrentDBDocument active_view = doc.ActiveView.Id # Get link document with rooms by keyword in filename - NOTE: Case Sensitive bip = ElementId(BuiltInParameter.ELEM_TYPE_PARAM) pfrf = ParameterFilterRuleFactory.CreateContainsRule(bip, "Architect") epf = ElementParameterFilter(pfrf) link_instance = ( FilteredElementCollector(doc) .OfCategory(BuiltInCategory.OST_RvtLinks) .WherePasses(epf) .FirstElement() .Id ) OUT = ( FilteredElementCollector(doc, active_view, link_instance) .OfCategory(BuiltInCategory.OST_Rooms) .ToElements() )
