Instance shared parameters from a different family show up in properties

[HVAC-Novice]

when I select one mechanical family in the model, I can see and adjust instance shared parameters in the properties bar. But the properties bar also shows me shared instance parameters from a different mechanical family (from a radiator in my example). i verified that the UH family doesn't have those shared parameters. This makes the properties bar too busy. 

What is going on and how can I make Revit only show the instance parameters of the family selected? 

I circled the parameters that belong in there.

Are both of those shared parameter show up in the project parameter list? If those parameter added within family, it may not showup with other family unless you add those same shared parameter into the project. Often I don't bother with Manufacturer shared parameter. I would add your own if you want all future mechanical family to share the same shared parameter.

If the parameters are added to the category in the project then they will show for every family instance of that category.

All the parameters in question are created by myself. Also all the ones shown are part of the project since the families they are used in are in the project. So that is all as expected.

But what I would expect when I select a family in the project, that the properties bar only shows the instance parameters of that specific family. The properties bar is used to see the values, and to edit them for that specific selected family (which is why it only shows instance and not type parameters). what i don't want (and can't see a reason why it would do that) is that if i select a family and it shows me ALL instance parameters of that entire category. Imagine 20 different type of mechanical equipment families with all their different needs for parameters and that properties bar gets busy and confusing quickly.

Organize your Parameters into Groups is what I would do. It'll look cleaner and read easier.

That's the parameters mess you have encountered my friend.

i try to have them in applicable groups. but multiple Mechanical devices can have parameters in the same category (i.e. mechanical flow). So that doesn't help much. 

Revit also has the "feature "to put parameters into a different category if there is one family that has the same shared parameter. it seems where a shared parameter was in the first family i loaded, that will force the same grouping for families loaded later. I try to get that standardized through all families to avoid that. 

So it sounds there is nothing I can do to ONLY show the parameters in the family selected. it is nicer to enter values in schedules since there I decide what is shown. But sometimes it is more convenient to do that in properties and some parameters are not scheduled.

Are you talking about how the Family Grouping gets f'd up in the Project? Yah, that's always been a sore point for me as well.  The fix is a pain in the buttocks.  You need an add-in or Dynamo.  Check Ideate.

The grouping is  a secondary problem and only would help a tiny bit (it still would show parameters not related to the selected family).

With very strict discipline (e.g. making sure all families I create have a specific shared parameter is in the same group) I can deal with the grouping issue. Although, it would be nice if Revit wouldn't force the project grouping into the families. 

If I could have the parameters that are not in the selected family hidden, grouping would be less relevant due to fewer things to see. 

[barthbradley]

Ha! Well, grouping is just a way to lessen the parameters significance in the Pallet since you can't make the parameters go away.

thanks all. I created an idea for this
