MEP system condition

[brane1012]

Hi All,

Best regards, Branimir.

Get all the elements of category pipes → Connect to GetParameterByname with name of Parameter System Types → Use List.GroupByKey node with list of your pipes and key with Output of SystemTypes. That will group your pipes with system types. After you group your pipes with system types use Element.GetLocation that will return lines as output. Use Line.Direction node to get the direction of pipes. Connect Vector.Normalized Vector.Normalized gives us …
