Usually drawings piping Hot and cold water paths sweep Use the arrow Show.
Hot water> red arrows continuous
Cold water> blue arrows continuous
Is this possible in Revit MEP automatically?
Revit has no ability to create true flow arrows. You would have to create a Generic Annotation family and manually apply it. There may be other suggestions out there - just search this forum with terms like "Flow Arrow" and see if you can find any useful information.
Thank you very much your answer.
Yes, I've used this method.
But I thought maybe there is a better way.
