3. Layers and the Export#

With the captured shape correct, the next step is assigning surfaces to layers.

Why layers matter#

Every captured surface is placed on a layer, and one acoustic material is assigned per layer after import. By default surfaces are grouped by Revit category, so every wall in the room — heavy masonry, stud partition, stage enclosure — arrives on PAV_Walls.

Assign types to layers#

  1. Open Settings → Capture Settings, and click Edit... beside Type layers. The dialog lists every element type of the selected categories in the venue.
  2. Give the acoustically distinct types their own layer names:
  3. heavy masonry separately from lightweight partitions;
  4. the stage enclosure separately from the side walls;
  5. seating separately from the floor beneath it;
  6. glazing separately from solid wall.
  7. Clear Include for anything acoustically transparent, and anything captured that is not part of the room.

Assigning types to layers

Unassigned types remain on their category layer.

Capture again#

Click Capture Venue. The DWG is overwritten with the new result.

Import the file#

The DWG is at the path set in Settings → Project Info. Import it following the documentation for the simulation software, and confirm on import:

  1. The units match the project's units.
  2. The layers are present as separate layers. Where all geometry arrives on layer 0, the layers were not read on import.
  3. The enclosed volume corresponds to the volume of the room. A significant difference indicates a missing surface — return to the review view in Revit and locate it.

Restore the diagnostic settings#

Disable Keep export view in Settings → Application Settings → Diagnostics. Each run otherwise adds a view and a set of surfaces to the model.
