Member Function Documentation

◆ alignDirection()

bool OdDbLoftOptions::alignDirection ( ) const

Returns the value of the direction alignment flag.

THe direction alignment flag is used to orient each of the cross sections so that the normal vector of each cross section points towards the next cross section. The default value is true. If the cross sections are not all oriented in the same direction, then this flag should be used to avoid creating a twisted or self-intersecting surface.

◆ arcLengthParam()

bool OdDbLoftOptions::arcLengthParam ( ) const

Returns the flag determining whether arc length parameterization is applied.

◆ checkCrossSectionCurves()

OdResult OdDbLoftOptions::checkCrossSectionCurves	(	OdDbEntityPtrArray &	crossSectionCurves,
		bool &	allOpen,
		bool &	allClosed,
		bool &	allPlanar,
		bool	displayErrorMessages = `false`
	)

Checks whether cross section curves are valid for the lofting operation.

Parameters

crossSectionCurves	[in] A list of cross-section curves.
allOpen	[out] A passed-in parameter indicating whether all of the cross-section curves are open.
allClosed	[out] A passed-in parameter indicating whether all of the cross-section curves are closed.
allPlanar	[out] A passed-in parameter indicating whether all of the cross-section curves are planar.
displayErrorMessages	[in] Indicates whether error messages are displayed. Default value is false.

Returns: Returns eOk if curves are valid or eInvalidInput otherwise.

Remarks: The method is called by createLoftedSurface() and createLoftedSolid() methods, so it is not necessary to call the method separately().

		bool	displayErrorMessages = `false`
	)

displayErrorMessages	[in] Indicates whether error messages are displayed. Default value is false.

Returns: Returns eOk if guide curves are valid or eInvalidInput otherwise.

Remarks: The method is called by createLoftedSurface() and createLoftedSolid() methods, so it is not necessary to call the method separately().

◆ checkLoftCurves()

		bool &	allPlanar,
		bool	displayErrorMessages = `false`
	)

Checks whether cross section curves and path curves are valid for the lofting operation.

Parameters

crossSectionCurves	[in] A list of cross-section curves.

Returns: Returns eOk if curves are valid or eInvalidInput otherwise.

Remarks: The method is called by createLoftedSurface() and createLoftedSolid() methods, so it is not necessary to call the method separately. The method combines calls to check CrossSectionCurves(), checkGuideCurves(), and checkPathCurve() into a single function.

Parameters

rhs	[in] Another OdDbLoftOptions object to assign.

void OdDbLoftOptions::setAlignDirection ( bool alignDir )

Sets the value of the direction alignment flag.

The direction alignment flag is used to orient each of the cross sections so that the normal vector of each cross section points towards the next cross section. The default value is true.

If the closed flag is set to false, the surface is opened or capped with a planar surface at the first and last cross sections. If the flag is set, then there must be at least three cross sections.

The default value is false.

Parameters
