Hello,
I see your family but i have no idea what is that device.
I will tell you how to use yes/no parameter step by step.
You can control 1 view with this parameter . For 2 views you need to create 2 family types with 2 yes/no parameters
- Open the family in Family Editor
- In the Project Browser go to Floor Plans and open Ref. Level.
- Select the area you want to control visiblity of.
- Go To Properties, Under Graphics select the Associate Family Parameter Option Bar (A pop up window will appear)

5. In the Associate Family Parameter window select “Add Parameter” located at the bottom left.

6. A new Parameter Properties window will open.
- Name describing this option
- Yes/No should already be selected as Type of Parameter
- Group under Graphics (this is where it will be listed in properties for you to turn on/off),
- Select Instance
- Select ok

7. Select OK.
8. Load edited family back into Project.

9. If family already exists in project you will get this window. Select Overwrite the existing version and its parameter values

10. Now Select the family in view and go to Properties to find the new parameter you created. Check or Uncheck for that view.
