Detailed Description

Function Documentation

def MakePartition	(		self,
			ListShapes,
			ListTools = [],
			ListKeepInside = [],
			ListRemoveInside = [],
			Limit = ShapeType["AUTO"],
			RemoveWebs = 0,
			ListMaterials = [],
			KeepNonlimitShapes = 0,
			theName = None
	)

Perform partition operation.

Parameters

ListShapes	Shapes to be intersected.
ListTools	Shapes to intersect theShapes.
Limit	Type of resulting shapes (see ShapeType()). If this parameter is set to -1 ("Auto"), most appropriate shape limit type will be detected automatically.
KeepNonlimitShapes	if this parameter == 0, then only shapes of target type (equal to Limit) are kept in the result, else standalone shapes of lower dimension are kept also (if they exist).
theName	Object name; when specified, this parameter is used for result publication in the study. Otherwise, if automatic publication is switched on, default value is used for result name.

Note

Each compound from ListShapes and ListTools will be exploded in order to avoid possible intersection between shapes from this compound.

After implementation new version of PartitionAlgo (October 2006) other parameters are ignored by current functionality. They are kept in this function only for support old versions.

Parameters

ListKeepInside	Shapes, outside which the results will be deleted. Each shape from theKeepInside must belong to theShapes also.
ListRemoveInside	Shapes, inside which the results will be deleted. Each shape from theRemoveInside must belong to theShapes also.
RemoveWebs	If TRUE, perform Glue 3D algorithm.
ListMaterials	Material indices for each shape. Make sence, only if theRemoveWebs is TRUE.

Returns

New GEOM.GEOM_Object, containing the result shapes.

def MakePartitionNonSelfIntersectedShape	(		self,
			ListShapes,
			ListTools = [],
			ListKeepInside = [],
			ListRemoveInside = [],
			Limit = ShapeType["AUTO"],
			RemoveWebs = 0,
			ListMaterials = [],
			KeepNonlimitShapes = 0,
			checkSelfInte = False,
			theName = None
	)

Perform partition operation.

This method may be useful if it is needed to make a partition for compound contains nonintersected shapes. Performance will be better since intersection between shapes from compound is not performed.

Description of all parameters as in previous method MakePartition(). One additional parameter is provided:

Parameters

checkSelfInte

The flag that tells if the arguments should be checked for self-intersection prior to the operation.

Note

This algorithm doesn't find all types of self-intersections. It is tuned to detect vertex/vertex, vertex/edge, edge/edge, vertex/face and edge/face intersections. Face/face intersections detection is switched off as it is a time-consuming operation that gives an impact on performance. To find all self-intersections please use CheckSelfIntersections() method.

Passed compounds (via ListShapes or via ListTools) have to consist of nonintersecting shapes.

Returns

New GEOM.GEOM_Object, containing the result shapes.

Example

References geomBuilder._autoPublish(), geomBuilder.BoolOp, geomBuilder.EnumToLong(), geomBuilder.Partition(), geomBuilder.RaiseIfFailed(), and geomBuilder.ShapeType.

def Partition	(		self,
			ListShapes,
			ListTools = [],
			ListKeepInside = [],
			ListRemoveInside = [],
			Limit = ShapeType["AUTO"],
			RemoveWebs = 0,
			ListMaterials = [],
			KeepNonlimitShapes = 0,
			theName = None
	)

See method MakePartition() for more information.

Example 2

References geomBuilder.MakePartition(), and geomBuilder.ManageTransactions().

def MakeHalfPartition	(		self,
			theShape,
			thePlane,
			theName = None
	)

Perform partition of the Shape with the Plane.

Parameters

theShape	Shape to be intersected.
thePlane	Tool shape, to intersect theShape.
theName	Object name; when specified, this parameter is used for result publication in the study. Otherwise, if automatic publication is switched on, default value is used for result name.

Returns

New GEOM.GEOM_Object, containing the result shape.

Note

This operation is a shortcut to the more general MakePartition operation, where theShape specifies single "object" (shape being partitioned) and thePlane specifies single "tool" (intersector shape). Other parameters of MakePartition operation have default values:

• Limit: GEOM::SHAPE (shape limit corresponds to the type of theShape)
• KeepNonlimitShapes: 0
• KeepInside, RemoveInside, RemoveWebs, Materials (obsolete parameters): empty

I.e. the following two operations are equivalent:

Result = geompy.MakeHalfPartition(Object, Plane)
Result = geompy.MakePartition([Object], [Plane])

def Archimede	(		self,
			theShape,
			theWeight,
			theWaterDensity,
			theMeshDeflection,
			theName = None
	)

Perform an Archimde operation on the given shape with given parameters.

The object presenting the resulting face is returned.

Parameters

theShape	Shape to be put in water.
theWeight	Weight of the shape.
theWaterDensity	Density of the water.
theMeshDeflection	Deflection of the mesh, using to compute the section.
theName	Object name; when specified, this parameter is used for result publication in the study. Otherwise, if automatic publication is switched on, default value is used for result name.

Returns

New GEOM.GEOM_Object, containing a section of theShape by a plane, corresponding to water level.
