Changing nested family w/ parameter

[Jessicas]

Hi,

I've got a sink family with a nested faucet. The faucet has a parameter assigned so that the faucet can be changed for a different one if we want.

It was working, needless to say today when I need to change the faucet I get the error "Can't use this type in this host"  -_- 

From what I can see both faucet families have the same settings. 

Help?

Thanks

Works fine.  Nothing wrong with them.

[Jessicas]

serious? Because its still not working for me...

[ToanDN]

Did you open the family I sent?

[Jessicas]

Yup, once I load it into my project I receive the "Can't use this type in this host" error still.

Works perfectly for me too!

I dont know what the issue is.... -_- this is really frustrating. I've attached a project file with the sink loaded in but I still get the exact same issue. It sort of looks like its trying to move the faucet. In fact it looks like its an issue with the original faucet that is on the sink and not the new one. 

My work day is finished so I will be back at this tomorrow.

Thanks for your help.

Try this.  I added a reference plane and re-constrain the faucet to it.

We finally got it to work. 

We ended having to open the faucet families and open the nested family with the model work and save that as the family we wanted to insert. Apparently our revit wasnt liking the family having a nested family. 

So now it works. 

I have no idea how it worked for you guys and not for us. In the family it would work fine for me but as soon as it was loaded into a project I could no longer change the faucet type.

The original family did not work in project as you described because the nested family was over-constrained. Try open the second one, which I have fixed and tested to make sure it worked in project.

I tried all the sinks you shared @ToanDN. I believe that they should work but for what ever reason I kept getting the same "Can't use this type" whatever it says error. 

I really appreciate you trying to fix it. 

[ToanDN]

You are correct. I opened the file I uploaded and it still had the same error.  I hate to give up like that so I tried once more and it works this time around.  I did close and re-open and it still works.
