Piping Classification and Piping System

[lee.imbimbo86EM4]

I'm hoping that someone here can explain this to me, because for the life of me I can't seem to get this to work.  I downloaded this Revit Family for a Air Handler Unit from the Manufacturer.  See attached.  It has a Refrigerant Gas, Refrigerant Liquid, and then three different Drain Types.  All listed under the Connector Description in it.  However, while they did this in the Connector Description, they left the Classification  set to Global. 

First, how the heck do you add piping systems to a family?  I know how to do it in my model, but the same Piping Systems Family that's in my model doesn't appear in Family.

Second, when I insert this into my model it has the effect of every thing I connect to it tries to allocate itself solely as a Sanitary Line, and it won't let me change the classification.

I'm hoping that someone here can help me figure this out.

There are no pipes in families. 

I would correct the connector settings to align with your systems properties. 

[lee.imbimbo86EM4]

I wouldn't mind doing that, but all it defaults to is the system defaults.  I'm mean on some level you could call this Hydronic Supply.  But other than the system defaults, how do you select anything other?

[RobDraw]

Each of your systems are based on one of the defaults. I woul set each if the connectors to correspond with whatever your systems are based on. I would use Other for Refrigerant but you may have something different for your content.

Looks like a VRF ducted unit. You should look at the cut sheet to verify what is what and edit if needed. For example, the conduit connectors also may need electrical connectors. 

Always understand and edit your own families! For example, the emergency drain is "global", while you likely want it to be sanitary. 

The system classification is what matters in the model. The description is just text. Whatever you call it doesn't matter except to you to know.

Enkus, I suspect you're trying to be helpful, but please don't presume this is my first rodeo.  I've modelled and remodelled hundreds of families.  I'm a little newer to the MEP stuff admittedly, but my questions wasn't some novice what are the basics question.  It was a direct one regarding piping systems, and how to assign them when working within a family.  Already out the gate suggesting that I'm not a novice that doesn't know what it means to import a manufacturer's families.

I've been practicing for close to 25 years, and been doing CAD since release AutoCAD 10.  Even with third party blocks in CAD the standard practice was to always clean the **** up to make it actually work.  My question wasn't one of "Hey what are standard practices when starting with a manufacturer family."  Instead it was "How do you add more piping systems to a mechanical family, when the controls for those piping systems aren't provided for in the family?"

If your intention is to help, then great.  I look forward to it.  But if that was your intention than you need to rethink your choice of language.  Because your comment basically comes of as some half-assed know nothing pretending they have big game, when they really have nothing of value to offer.

Regarding a follow up to your comment, I have a condensate drainage system in my model, but it won't let me import the family.  and the refrigerant lines it keeps defaulting to Sanitary, when inserted into the model, and then locks it and won't let me change it.

Wow. Someone's being a little sensitive. 

You're welcome. I'm out.

hmmm, maybe it just took a moment to load after your post.  But thank you for the post.  So interesting enough I had to delete the family from the model and purge it, then reload it, and it let me do what you're showing in the video.

That being said, I guess I was hoping that I could go about defining this in the family.  In effect make a piping system in the family that is refrigerant gas and liquid, and then another for condensate.  Then when you go about drawing the pipe out of the system is just defaults to the correct one.  But it would appear that there is no ability to define these piping systems beyond the system defaults within the family.  Is that correct?

[evgeny.kurbatov · Accepted solution]

That's correct. You cannot create piping systems in Families. For a piping connector you can assign the System Classification which is a fixed list of choices. Read more here.

The idea for the post solution is - have the pipe system assigned BEFORE connecting it to the equipment. BTW, I like the following workflow. Draw pipes with the systems you need (do not connect to the equipment). Then select the equipment and use the menu command Connect Into. It gives you a chance to connect equipment pipe connectors to correct pipes/systems.
