The title is maybe a little confusing. For example, I had a List<Element> elements. As shown in the figure below, the System Tab owns various element types: HVAC type, Fabrication type, Mechanical type, Piping type, Electrical type. I need to classify the elements list by these types. Is there any method to implement this?
Use FilteredElementCollector to collect elements and get the type of the elements and with the help of the type classify the elements
FilteredElementCollector Collector = new FilteredElementCollector(doc).WhereElementIsNotElementType();
IList<ElementId> all_eids = Collector.ToElementIds() as IList<ElementId>;
IList<ElementId> mech_ids = new List<ElementId>();
IList<ElementId> elec_ids = new List<ElementId>();
IList<ElementId> HVAC_ids = new List<ElementId>();
IList<ElementId> piping_ids = new List<ElementId>();
IList<ElementId> fabrication_ids = new List<ElementId>();
foreach(ElementId eid in all_eids)
{
Element e = doc.GetElement(eid);
Type T = e.GetType() as Type;
if(T.Name.Contains("Mechanical"))
{
mech_ids.Add(e.Id);
}
if(T.Name.Contains("Electrical"))
{
elec_ids.Add(e.Id);
}
if(T.Name.Contains("HVAC"))
{
HVAC_ids.Add(e.Id);
}
if(T.Name.Contains("Piping"))
{
piping_ids.Add(e.Id);
}
if(T.Name.Contains("Fabrication"))
{
fabrication_ids.Add(e.Id);
}
}
Hi @Anonymous,
You can also approach by using with the below code
FilteredElementCollector mech_coll = new FilteredElementCollector(doc).OfClass(typeof(MechanicalSystem)).WhereElementIsNotElementType();
IList<ElementId> mech_ids = mech_coll.ToElementIds() as IList<ElementId>;
