Number of elements connected to a piping system

[brunothiagorvs]

I'm creating a user MEP calculation for plumbing fixture flow using a sample avaliable at https://thebuildingcoder.typepad.com/blog/2013/07/user-mep-calculation-sample.html

Is it possible to get the number of elements connected to the piping system from which the current pipe belongs to?

In other words, I want to use the number of elements connected as a variable to calculate the flow.

Hi @brunothiagorvs ,

Try using the below link

Traversing an MEP System and Retrieving Connected Elements

[reylorente1]

public Result Execute(
ExternalCommandData commandData,
ref string message,
ElementSet elements)
{
UIApplication uiapp = commandData.Application;
UIDocument uidoc = uiapp.ActiveUIDocument;
Aplicación app = uiapp.Application;
Document doc = uidoc.Document;

string mep_seccion = "";

//Recorriendo el Sistema MEP
foreach (MEPSystem MEPSystem in new FilteredElementCollector(doc)
.OfClass(typeof(MEPSystem)))
{
List<MEPSection> seccionMeplista = new List<MEPSection>();
getSectionsFromSystem(MEPSystem, seccionMeplista);

foreach (MEPSection secc in seccionMeplista)
{
mep_seccion += secc.Number.ToString() + Environment.NewLine;
}
}
