Acoustic requirements on walls are of the category, Generic Model.

When working with wall requirements there is a vast amount of requirements per project. 


Open Quick Wall Settings to define up to six different requirements which will appear on the six buttons.


Choose up to six different requirements in the drop-down menu. That list all Generic model and Audio Visual Devices within the project. 


Remember, to use your own symbols the requirement must be a line-based family. 


Choose from different requirements within the project such as


  • Acoustic Rating Wall
  • Disturbance level walls
  • Acoustic level wall.



The text for each button is now updated after the Type name.


It's recommended to connect each requirement to a keyboard shortcut. Note: Restart Revit to have the text from the requirement to be updated in the keyboard shortcut list. Otherwise, it will still be Quick 1-6 from start. 


Note: If a requirement is missing, contact the BFT team and they will create it ASAP and deliver the missing requirement.


The Tool itself only lets the users select Wall categories.


The height of the wall will be copied to the parameter “BFT_Top”, and the length of the wall will be applied to the length of the family meaning they should be identical. 


Note: If the wall in the linked model has used “Attach top” / “Edit profile” the engineer needs to manually update the wall requirement height.


The line-weight, line style and colour can be controlled under Manage → Object Styles → Generic Models. 


The wall requirements have three different requirements:

  • AcousticReq_AcousticLevelRating
  • AcousticRatingReq, which is always the same value as AcousticReq_AcousticLevelRating.
  • AcousticReq_Comments



BFT_GUID is a parameter, showing the user that this specific requirement is connected to a component in the linked model.
