Control Visibility of 3 Yes/No Parameters

[Kev_D]

Hey

I have created a Door Family which has 3 different door panels applied. Type A = Door Flush Panel, Type B = Door Panel with 1 Glazed Panel, and Type C = Door Panel with 2 Glazed Panels. I have created types for each (A, B & C) and the visibility is turned off on the 3 types that are not being used. So when A is being used the other two are turned off (but have to be turned off manually). Is there a formula to use to turn off two visibilities automatically when one is switched on. I am aware of the not(parameter) to control 2 visibilities, but how do you control 3?

Are the door panel families nested and shared in the door family?

See Munkholm's post here:

Lots of other good stuff in it too.

Yes the panels are all separately nested but not shared. No need to share I don't think. I have carried all the parameters through.

Yes/No parameters work best when there are two.  When you have more than two, such as your case, it's better using Family type parameter to control types.

Yes I have looked at this link many times. Some great info there. He only discusses controlling 2 visibilities, not 3. Unless I am blind.

Thank you. Yes I have created the types, but when new types are created/duplicated within a project I would like to my team to choose a panel type they require and then for me to not worry if they unchecked the other types. So I was hoping I could control this with a formula.

That is exactly what a Family Type parameter is for .  See the example door family (2016).

Thank you.

@ToanDN

So, I made the family types like you said.

There are 3 door panles, and each panel is chosen to match the type. All good so far.

When I load it into the project and change the types, the parameter value changes to the proper type, but the actual panel in the model does not change. see images.

So the first is straight forward and shows the type of panel associated with that family type.

 

however, when I change the family type to another, all the values change but the actual door does not.   

Any ideas why?

[ToanDN]

Can you share the door family?

[Kev_D]

@ToanDN

Family attached

[ToanDN]

None attached.

[barthbradley]

..and you are sure the nested family in the host family has been assigned the label? And, that it is the correct family type? 

[Kev_D]

It is there now

[Kev_D]

@ToanDN

That is it by the looks of things. Always a simple thing you forget.

[ToanDN]

- You did not assign the label to the nested panel

- Do not insert all three nested panels in the door family model space, only one

[Kev_D]

Somethin doesn't add up here. If I don't load the 3 panels into the family, how can I assign the different panels to the different family types. 

[cbcarch]

Maybe it has something to do with a Family Type Catalog?

I see that you posted a solution already, so I don't know if this information is needed now, but the Family Types Parameter is specific to a Family Type. For instance, if it's a <Generic Model> type, the drop-down will show all the Generic Model Types that are loaded into the Family -- whether or not they are components you what to use/swap out for.  Additionally, when you load this Family into the Project, that Family Type Parameter drop-down will populate with every shared family type in the Project.  This can be a little problematic.  So, just an FYI FWIW.
