CadnaR 2022

Calculation / Configuration

New function: "Calibrate spectra" for automatic adjustment of material properties (absorption coefficients, scattering coefficients) to achieve user-defined target reverberation time
Possibility to now define scattering coefficient globally for all objects and surfaces of surrounding room
Scattering coefficient can now be defined per surface of the surrounding room

Multi-selection of several objects possible, e.g.
- in 2D-View drag frame with right mouse button pressed
- add objects to multi-selection: keep CTRL key pressed and drag frame in 2D view with right mouse button or click on single object
- add objects to multi-selection in 3D-view: CTRL + click with right mouse button on single object
Object tables can be filtered to show current multi-selection
New attribute MULTISEL to also allow modifying the multi-selection via object-tables and "Motify Object | Modify Attribute"
New attribute LENAREA for barrier: Area (one side of the barrier, half of the barriers total surface)
Attribute LENAREA vert. Polymesh: now automatically uses triangulation to determine the area (one side, half of total surface)

3D view: Move camera perpendicular to the direction of view with middle mouse button pressed + mouse movement
"Clean Tables" now also deletes unused 2D and 3D library symbols
Dialog “Appearance” now accessible via button in the toolbar. Switch object visibility on and off by double-clicking on entry in the object list.
Update DXF Export: box-type Obstacles and Box-type Sources nows exported as 6 rectangles, Vert. Polymesh exported as triangles
Diagram for Reverberation time: target reverberation time for "Calibrate spectra" can be displayed via submenu "User-defined reference reverberation times"

Consistency check: Check object expansion adapted to min 1mm length/height or 10mm² base area
Consistency check: Warning if grid height outside the surrounding room
