Detailed Description

Provides CAD Exchanger data model.

The model encapsulates a scene graph (hierarchy of assemblies and parts) and is thus an entry point to entire 3D model data.

A model contains a shared pointer to its internal implementation, so simple copying an object will just copy a shared pointer:

ModelData_Model aModel2 = aModel; //both objects will point to the same contents

The model object can be saved to and restored from a file in native CAD Exchanger format. Currently binary format is used as a file type.

bool anIsOk = aModel.Save ("mydocument.cdx");
 
ModelData_Model aNewModel;
anIsOk = aNewModel.Open ("mydocument.cdx");

Member Enumeration Documentation

FileFormatType

enum cadex::ModelData_Model::FileFormatType

Defines file format used to store model contents.

Deprecated:

Kept for preserving binary compatibility.

See also

ModelData_WriterParameters::FileFormatType.

Constructor & Destructor Documentation

ModelData_Model()

cadex::ModelData_Model::ModelData_Model

(

const Base_UTF16String &

theName = Base_UTF16String()

)

Constructor.

Creates an empty model. IsEmpty() returns true.

Member Function Documentation

AddRoot()

const ModelData_SceneGraphElement & cadex::ModelData_Model::AddRoot

(

const ModelData_SceneGraphElement &

theElement

)

Adds new root element into the scene graph.

If the passed element is an instance of ModelData_Instance, it will be automatically nested in ModelData_Assembly according to product structure requirements.

Examples

MTKConverter/Program.cs, meshing/lods/Program.cs, meshing/lods/main.cxx, meshing/remeshing/main.cxx, modeling/assembly/Program.cs, modeling/assembly/main.cxx, modeling/brep/Program.cs, modeling/brep/main.cxx, modeling/brepfeatures/Program.cs, modeling/brepfeatures/main.cxx, modeling/brepprimitives/Program.cs, modeling/brepprimitives/main.cxx, modeling/metadata/Program.cs, modeling/metadata/main.cxx, modeling/poly/Program.cs, modeling/poly/main.cxx, visualization/offscreen/main.cxx, and wall_thickness/visualization/main.cxx.

AssignUuids()

void cadex::ModelData_Model::AssignUuids

(

)

Assigns uuid's (persistent id's) to scene graph elements and part representations (if not assigned yet).

Examples

MTKConverter/Program.cs, and MTKConverter/main.cxx.

Clear()

void cadex::ModelData_Model::Clear

(

)

Clears the model contents.

Detaches the model contents. Only cleans up contents of this object. Other copies of this object will remain unaffected. For instance, in the following code

ModelData_Model aM1;
//... populate aM1;
ModelData_Model aM2 = aM1;
aM1.Clear();

the aM2 object will continue to have entire previous contents. Respectively, all previous pointers (e.g. to objects of ModelData_BaseObject subclasses) remain valid.

See also

IsEmpty().

Examples

meshing/remeshing/Program.cs, and meshing/remeshing/main.cxx.

IsEmpty()

bool cadex::ModelData_Model::IsEmpty

(

)

const

Returns true if the model is empty.

Returns true if the model has no roots, i.e. NumberOfRoots() returns 0.

See also

Clear().

Examples

MTKConverter/Program.cs, and MTKConverter/main.cxx.

Merge()

void cadex::ModelData_Model::Merge	(	const ModelData_Model &	theSrcModel,
		const Base_ProgressStatus &	theProgressStatus = Base_ProgressStatus()
	)

Adds all roots of another model to the current model.

Adds roots from another model to current.

Name()

const Base_UTF16String & cadex::ModelData_Model::Name

(

)

const

Returns a model name.

Returns empty string if the model has no name (by default).

See also

SetName().

Examples

MTKConverter/Program.cs, MTKConverter/main.cxx, Unity/Assets/Scripts/Editor/ModelLoaderWizard.cs, advgeom/brepsimplify/Program.cs, advgeom/brepsimplify/main.cxx, advgeom/meshsimplify/Program.cs, advgeom/meshsimplify/main.cxx, conversion/cdxwebconverter/Program.cs, conversion/import/Program.cs, conversion/import/main.cxx, machining/dfm_analyzer/main.cxx, machining/feature_recognizer/main.cxx, sheet_metal/dfm_analyzer/main.cxx, sheet_metal/feature_recognizer/main.cxx, sheet_metal/unfolder/main.cxx, wall_thickness/analyzer/main.cxx, and wall_thickness/visualization/main.cxx.

NumberOfRoots()

size_t cadex::ModelData_Model::NumberOfRoots

(

)

const

Returns number of root elements in the graph.

See also

AddRoot(), ElementIterator, IsEmpty().

Examples

conversion/cdxwebconverter/Program.cs, conversion/import/Program.cs, and conversion/import/main.cxx.

Open()

bool cadex::ModelData_Model::Open	(	const Base_UTF16String &	theFileName,
		bool	theToAppend = false,
		const Base_ProgressStatus &	theProgressStatus = Base_ProgressStatus()
	)

Loads the model object from the file.

If theToAppend is true then appends to this model, otherwise resets it first.

The method can be called on a nullified model.

See also

Save().

Properties()

ModelData_PropertyTable cadex::ModelData_Model::Properties

(

)

const

Allows to get property table from ModelData_Model class.

The main purpose of this table is to store information about measurement units of the original read file.

You can get information about them from ModelData_PropertyTable using predefined keys:

ModelData_PropertyTable::OriginalLengthUnitPropertyName() ModelData_PropertyTable::OriginalAngleUnitPropertyName()

See more information on Measurement Units.

RemoveRoot()

bool cadex::ModelData_Model::RemoveRoot

(

const ModelData_SceneGraphElement &

theElement

)

Removes root scene graph element from the model.

Returns true if removal took place and false otherwise.

Warning

A call to this function resulting in true value invalidates the instances of ModelData_Model::ElementVisitor and ModelData_Model::ElementIterator over model's roots, making further behavior of these objects undefined.

Examples

modeling/elementremoval/main.cxx.

Save() [1/3]

bool cadex::ModelData_Model::Save	(	const Base_UTF16String &	theFileName,
		const Base_ProgressStatus &	theProgressStatus = Base_ProgressStatus()
	)		const

Saves the model object to a CDX file.

Kept for preserving binary compatibility. Invokes ModelData_Model::Save(const Base_UTF16String&, const ModelData_WriterParameters&, const Base_ProgressStatus&);

Examples

MTKConverter/Program.cs, and MTKConverter/main.cxx.

Save() [2/3]

bool cadex::ModelData_Model::Save	(	const Base_UTF16String &	theFileName,
		const ModelData_WriterParameters &	theParameters,
		const Base_ProgressStatus &	theProgressStatus = Base_ProgressStatus()
	)		const

Saves the model object to a file.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Any folders you specify in the output path that are not yet present in the filesystem will be created automatically.

Note

Saving the model in CDXWEB format is not supported for the WIN32 platform.

See also

Open().

Save() [3/3]

bool cadex::ModelData_Model::Save	(	const Base_UTF16String &	theFileName,
		FileFormatType	theFormat,
		const Base_ProgressStatus &	theProgressStatus = Base_ProgressStatus()
	)		const

Saves the model object to a file. This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Deprecated:

Kept for preserving binary compatibility. Invokes ModelData_Model::Save(const Base_UTF16String&, const ModelData_WriterParameters&, const Base_ProgressStatus&);

SetName()

void cadex::ModelData_Model::SetName

(

const Base_UTF16String &

theName

)

Sets a model name.

Accepts a string as a unicode string.
