CompiledModelBlockNormalModeVisibility	For a top model that is being simulated or that is in a compiled state, return information about which Model blocks have normal mode visibility enabled.	Return values indicate which Model blocks have normal mode visibility enabled.
DefaultAnnotationFontName DefaultBlockFontName DefaultLineFontName	Name of font to use for new annotation text, block text, or signal line labels and on existing annotations, block names, or signal lines whose FontName property is set to 'auto'. To set, on the Format tab, click the Font Properties button arrow, then click Fonts for Model.	character vector
DefaultAnnotationFontSize DefaultBlockFontSize DefaultLineFontSize	Size of font to use for new annotation text, block text, or signal line labels and on existing annotations, blocks, or signal lines whose FontSize property is set to -1. To set, on the Format tab, click the Font Properties button arrow, then click Fonts for Model.	positive integer
DefaultAnnotationFontAngle DefaultBlockFontAngle DefaultLineFontAngle	Angle of font for new annotation text, block text, or signal line labels and on existing annotations, blocks, or signal lines whose FontAngle property is set to 'auto'. To set, on the Format tab, click the Font Properties button arrow, then click Fonts for Model.	{'normal'} | 'italic'
DefaultAnnotationFontWeight DefaultBlockFontWeight DefaultLineFontWeight	Weight of font for new annotation text, block text, or signal line labels and on existing annotations, blocks, or signal lines whose FontWeight property is set to 'auto'. To set, on the Format tab, click the Font Properties button arrow, then click Fonts for Model.	{'normal'} | 'bold'
HideAutomaticNames	Hides block names given automatically by the Simulink Editor. See Hide or Display Block Names.	{'on'} | 'off'
LineUpdate	Specifies when to update line routing to avoid overlapping lines and obstacles in the model. When set to the default 'deferred', scripts postpone line routing until they pause or complete. To perform deferred line routing within a script, you can use function Simulink.BlockDiagram.routeLine.	{'deferred'} | 'none' | 'immediate'
ModelBrowserVisibility	Show the Model Browser. In the Simulink Editor, in the Modeling tab, select Environment > Model Browser.	'on' | {'off'}
ModelBlockNormalModeVisibility	Use with set_param to set normal mode visibility on for the specified Model blocks. You can set this parameter with the Model Block Normal Mode Visibility dialog box. For details, see Specify Which Instance Has Normal Mode Visibility Enabled.	With set_param, use an array of Simulink.BlockPath objects or cell array of cell arrays of character vectors of paths to blocks or models. With set_param, an empty array specifies to use the Simulink default selection for the instance to have normal mode visibility enabled.
ModelBlockNormaModeVisiblityBlockPath	Return information about which Model blocks have normal mode visibility enabled. Use with a model that you are editing.	Return values indicate which Model blocks have normal mode visibility enabled. See Simulate Multiple Referenced Model Instances in Normal Mode.
PortDataTypeDisplayFormat	When you display port data types in a model, choose whether to display data type aliases, base data types, or both. In the Simulink Editor, in the Debug tab, set by Information Overlays > Base Data Types and Information Overlays > Alias Data Types.	{'AliasTypeOnly'} | 'BaseTypeOnly' | 'BaseAndAliasTypes'
ReqHilite	Highlights all the blocks in the Simulink diagram that have requirements associated with them. In the Simulink Editor, in the Apps tab, under Verification, Validation, and Test, click Requirements Viewer. The Requirements Viewer tab appears. Click Highlight Links.	'on' | {'off'}
SampleTimeAnnotations	In the Simulink Editor, in the Debug tab, select Information Overlays > Text.	'on' | {'off'}
SampleTimeColors	In the Simulink Editor, in the Debug tab, select Information Overlays > Colors.	'on' | {'off'}
ScreenColor	Background color of the model window. In the Simulink Editor, on the Format tab, set Background.	'black' | {'white'} | 'red' | 'green' | 'blue' | 'cyan' | 'magenta' | 'yellow' | 'gray' | 'lightBlue' | 'orange' | 'darkGreen' | [r,g,b,a] where r, g, b, and a are the red, green, blue, and alpha values of the color normalized to the range 0.0 to 1.0. The alpha value is ignored.
