Space analysis package/ Using Revit section to Analyse sound

Hey there,
I tried to explore the space analysis package recently to help create a design process to reduce sound, but I get a warning at the “SoundField.BySpaceLatticeAndSoundSystem” and I’m not able to run the script.

What I have done.

  1. Gathered elements such as walls, floor slab, windows roof that would be a major barriers.
  2. Selected a section plane from the model.
  3. Intersected the section plane and the element geometry to retrieve a section profile made of curves.
  4. Shifted the curves/lines to the xy axis as the package deals with 2d analysis.
  5. Create a sound source point and a sound receiving point.
  6. Followed a video on youtube regarding space analysis. Space analysis reference video.

Please If someone point out of help with what’s goin wrong.
I am using Revit basic sample project as main rvt file.
