Building Parametric REFNET JOINTS

So working for a mechanical contractor where accurate takeoff is a high priority.  Starting a REFNET refrigerant family as a single family object.

 

Below is a screenshot of the submittal.  The size steps are where the fitting can be cut to adapt to multiple sizes, along with extension joints to adapt to an even greater range.

At first I started building all of the components separately, then use visual YES/NO parameters to toggle on what's being used based on a type size of the inlet.  This won't work because of the connectors, they can only be located in the primary host of the part.  

So that leads me to attempting this parametrically, but the number of constrants and variables is a little bit mind boggling ATM.  (Keep in mind this is ACR Copper tubing, so the size tables add an additional level of confusion for me at least.)

 

So questions;

1. Is there a way to nest a connector in a part and have it readable by Revit?

2. Is there a way to toggle on and off the availability of a connector?  

I've added connectors to objects that were options by hosting them on their own solid, and literally pushing the part off of the view (voids) but this still leaves a floating connector in the project that can still be connected to if someone really wanted to.

 

3. Anyone have any thoughts on an object like this?  Gotta love a 1/2" - 1" copper pipe fitting that takes more parametrics to function than dang near any piece of Mecnahical Equipment I've ever made.

 

There's literally a ton of data missing off this cutsheet that has to be incorperated into the part as well, including solder joint depths, cut back points (unspecified, so my wild guess.) I can't even find documentation on the 1 to 2 pipe collector inlet to outlet center to center distances.

Hello,

 

Answering your questions:

 

1 - It is not possible to use connectors in nested families.

2 - Unfortunately, so far Revit does not allow to hide or make unavailable the existing connectors.

 

One issue that happened with nested fittings, at least until Revit 2016, that they does not connect to the system, so pipe systems colors overrides does not work!

 

Fittings are a real challenge sometimes...

Yes, @fabiosato did.  Thank you.  I didn't see a "Accept as Solution" button on this thread for some reason.

Hah of course they make them now.  I originally built these about a year ago and contacted them if they had anything available at that time.  I ended up driving the connector from a void, and using formulea to push/pull it to the new "trim" locations.  They were a mother that's for sure!

 

Thanks for the link, I'd rather use MFR equipment if they work half as well as mine!
