For example, specifying regex == NULL for a multi-surface will remove all traits at the root level of the multi-surface, whereas specifying regex == kFME_RecurseSome <string> will remove all traits from all levels of the multi surface that match <string>. If <string> is an illegal regular expression, no traits will be removed.

• newMeasureName (str) – The new name of the measure.

Return type:

None

reorient()

Flips the underlying surfaces that make up the solid, such that the front and back of each surface is switched. This has the effect of flipping the solid inside-out. The front and back vertex normals are swapped.

Return type:

None

resolvePartDefaults()

Recursively resolves surface parts with default appearances by replacing these defaults with the inherited appearance references stored by the parent surface, if such a value exists. The nearest non-default ancestor value will be used to set the default appearances on the part.

Return type:

None

reverse()

This reverses the order of the solid’s points.

Return type:

None

rotate2D(center, angle)

Rotates this solid about the z-axis by the specified angle, in degrees. The rotation is performed relative to the center specified. A positive angle corresponds to a counter-clockwise rotation, when looking down onto the XY-plane.

Parameters:

• center (FMEPoint) – The center point of the solid.

Return type:

None

Raises:

Return type:

None

Raises:

FMEException – An exception is raised if an error occurred.

setAppearanceReference(appearanceRef, front)

This method associates an appearance within the Library with this solid. This is done by passing in the unique appearance reference for this appearance. Subsequent calls to this method on the same side, will override the previous appearance used with the new appearance passed in.

An appearance reference of ‘0’ represents the default appearance. Interpretation of the default appearance is left to the consumer of this geometry. When set at this FMESolid level, the appearance represents the default appearance to apply when the contained surfaces use the default appearance instead of a specific appearance. Contained surfaces may be found within nested solids, geometry instances that reference geometries containing surfaces, or as surfaces or multi-surfaces.

The second parameter controls whether this action should take place on the front of the contained surfaces or the back. Both can be set independently. The ‘appearanceRef’ should be a valid reference to a definition stored in the FMELibrary. If the reference was not found in the library, it will still attach the reference to the instance, but will throw a FMEException. This is an unhealthy situation as it represents a ‘dangling reference’.

Parameters:

• appearanceRef (int) – The unique appearance reference for this appearance.

• front (bool) – Boolean indicting whether the appearance reference should be set for the front or back of the solid.

Return type:

None

Raises:

FMEException – An exception is raised if an error occurred or the reference was not found in the library and a dangling reference was attached.

setName(name)

Sets the geometry’s name with a str. By supplying a blank name as input, this method will act as deleteName().

Parameters:

name (str) – The geometry’s new name.

Return type:

None

setOuterSurface()

setOuterSurface(outerSurface),

Sets the outer surface of this boundary-representation solid as the specified FMESurface passed in. The outer surface of a boundary-representation solid must exist. Thus, if None is passed in, an error will result.

Parameters:

outerSurface (FMESurface) – The FMESurface to be used as the outer surface for the BRepSolid.

Return type:

None

Returns:

The existing BRepSolid with a new outer surface.

Raises:

FMEException – An exception is raised if an error occurred, or None is passed in.

setTrait(traitName, traitValue)

Sets a geometry trait with the specified value. If the geometry trait already exists, its value and type will be changed. The following type numeric mappings are used:

PyInt ==> FME_Int32

PyFloat ==> FME_Real64

PyLong ==> FME_Int64

Binary values are to be specified as bytearray values or bytes values.

Parameters:

• traitName (str) – The name of the geometry trait.

• traitValue (bool, int, float, str, bytearray, or bytes) – The value of the geometry trait.

Return type:

None

setTraitNullWithType(traitName, traitType)

This method supplies a null trait value with a type to the geometry. If a trait with the same name already exists, it is overwritten.

Trait type must be one of FME_ATTR_UNDEFINED, FME_ATTR_BOOLEAN, FME_ATTR_INT8, FME_ATTR_UINT8, FME_ATTR_INT16, FME_ATTR_UINT16, FME_ATTR_INT32, FME_ATTR_UINT32, FME_ATTR_REAL32, FME_ATTR_REAL64, FME_ATTR_REAL80, FME_ATTR_STRING, FME_ATTR_ENCODED_STRING, FME_ATTR_INT64, FME_ATTR_UINT64.
