10.3 ArrayCalc menu options and Toolbar
The drop-down menus "File", "View", "Sources","Extras" and
"Help" on top of the page provide access to additional
functions of ArrayCalc. Several menu items can also be
accessed directly by clicking the respective button in the
toolbar underneath.
10.3.1 File menu
— New: Creates a new project by loading the default
project. Modifying a simple existing setup is usually
much faster than starting without any data.
— Open / Save / Save as: Loads or saves the project
data including room data, arrays, SUB array design and
alignment settings from/to a file. (file format: *.dbac2).
It is possible to open setup files created with ArrayCalc
version 5.x, however additional data has to be provided
manually. Opening setups from earlier Microsoft Excel
based versions of ArrayCalc is not possible.
Note:
When saving an ArrayCalc project, all relevant
information for the related R1 Remote control
project such as amplifiers, groups and control
elements is generated and saved to the same file.
To operate the simulated ArrayCalc project in R1,
just open the respective *dbac2 file.
— Open recent project: Provides direct access to the
last six projects saved.
— Open example project: Provides direct access to
the example project files included in the installation
package.
— Export DXF: Exports all / the currently selected array
or the SUB array to a *.dxf graphics file. The units used
in the dxf-file are millimeters. However for compatibility
reasons the unit formatting in the dxf-file is omitted, hence
several CAD systems import the data as "unitless".
— Export EASE: Exports the selected array to a file which
can be imported by the d&b Line Array GLL or DLL for
EASE 4.x.
— Export PNG: Only available from the 3D plot page;
exports the 3D plot, the color scale and the underlying
signal selection to a *.png file.
— Print: Print options for several pages of ArrayCalc.
— Print preview: Provides access to a print preview with
several options (depending on the printer selected).
— New instance: Opens another instance of ArrayCalc.
— Exit: Closes ArrayCalc.
10.3.2 View menu
— Toolbar: Allows the toolbar to be switched on/off.
— Status bar: Allows the status bar to be switched
on/off.
10.3.3 Sources menu
When working on the Sources page, the Sources menu
provides the following functions:
— Add array: Adds a new empty array to the project.
The maximum number of arrays is fourteen.
— Auto splay: Provides starting values for the splay
angles of the selected array.
— Add point sources: Adds a new empty point sources
dialog to the project. The maximum number of point
source groups is fourteen. Each group may consist of up
to 14 single point sources. You can also select column
loudspeakers from this dialog by choosing xC-Series
from the system selection.
— Rename: Highlights the name of the selected source
for editing.
— Copy: Creates a copy of the selected source settings in
the internal clipboard.
— Paste: Pastes all source settings copied to the internal
clipboard into the selected source.
— Paste as new: Creates a new source containing all
settings from the internal clipboard.
— Delete: Deletes the selected source from the project
after confirmation.
— Export source: Exports the settings of the selected
source to an ArrayCalc description file (*.dbea for
arrays, *.dbep for groups of point sources, *.dbesa for
SUB arrays).
— Import source: Imports the settings of a source from
an ArrayCalc description file (*.dbea for arrays, *.dbep
for groups of point sources, *.dbesa for SUB arrays) to
the selected source.
10.3.4 Extras / Options menu
— Units: Provides access to the selection of:
the measurement units: metric (m/kg) or imperial (ft/lbs).
the temperature units: degrees centigrade (° C) or
Fahrenheit (° F).
— Web search: Provides access to automatic update
options.
— Graphics: Provides optional color palette for bright
environment.
— R1 project: Defines the start mode of the generated
R1 project.
— Air absorption: Provides access to the environmental
settings (temperature and humidity) which are primarily
relevant to calculate excessive absorption of high
frequencies in air (see also 9.6.10). For quick access to
the global Air absorption settings, an on-off switch is
available in the toolbar at any time. A shortcut to the
Extras/Options/Air absorption settings is provided there
as well to define temperature and humidity values.
10.3.5 Help menu
— F1 Help: Provides access to this document.
— Web search: Searches the web for updates.
— System info: Provides information on the computer
system.
— About: Provides information on the version of
ArrayCalc you are using.
