Multiple Values Result

[a1abrams694127]

Hello. Can anybody give me some pointers on why my duct systems show " multiple values" after I connected my systems. I use REVIT MEP 2013. and also the ducts do not show duct air flow...etc.... even if the system is connected.

thanks

Do you have the calculations turned off?

One of the improvements for 2013 is that you can use system colour fill to show the breakup of flow/ pressure etc in a duct with taps. Unfortunately this means, if you have taps, your duct will schedule and tag "Multiple values" as there is a different value for flow/ pressure etc before the tap compared to after it.

I checked the parameters on the duct systems and set the calculations to "ALL" and the result was that the duct members where there are taps display "multiple values" while those ducts after the taps show the values. Is this a bug within Revit?
Regarding Families, I made a model of an FCU, Samsung to be exact, and loaded it into a sample project, the thing is, when I tried to connect say a flow chw pipe to it, the pipe size in the model followed the size of the pipe that I was connecting. Something is definitely wrong with the family. Is there a way to fix this.

thanks guys.
