OdDbHelix Methods

	Name	Description
	axisPoint	Returns the start point of the axis for the helix.
	axisVector	Vector of the axis of the helix
	baseRadius	Base radius of the helix
	constrain	Returns the constrain property of the helix
	createHelix	This functions creates the helix geometry based on the values set in prior function calls. Without calling this function, no geometry will be visible on the screen.
	dwgInFields	Reads the .dwg file data of this object.
	dwgOutFields	Writes the .dwg file data of this object.
	dxfInFields	Reads the DXF data of this object.
	dxfOutFields	Writes the DXF data of this object.
	height	Height of the helix
	ODDB_DECLARE_MEMBERS	This is ODDB_DECLARE_MEMBERS, a member of class OdDbHelix.
	reverseCurve	Reverses this Spline entity.
	setAxisPoint	Sets the start point of the axis for the helix. axisPoint Input the 3D point where the axis starts bMoveStartPoint Input Boolean indicating whether to relocate the start point by the same offset
	setAxisVector	Sets the vector for the axis for the helix
	setBaseRadius	Sets the base radius of the helix
	setConstrain	Sets the constrain property of the helix
	setHeight	Sets the height of the helix
	setStartPoint	Sets the start point of the helix
	setTopRadius	Sets the top radius of the helix
	setTurnHeight	Sets the turn height (distance between threads)
	setTurns	Sets the number of turns (revolutions)
	setTwist	Sets the twist of the helix (is counter-clockwise)
	startPoint	Returns the start point of the helix
	subExplode	Replace OdRxObjectPtrArray
	subGetClassID	overridables
	subTransformBy	Applies the specified 3D transformation matrix to this entity.
	topRadius	Top radius of the helix
	totalLength	Returns the total length of the helix
	turnHeight	Turn height (distance between threads)
	turns	Number of turns (revolutions) of the helix
	turnSlope	Returns the turn slope angle of the helix
	twist	Returns the twist of the helix (clockwise or counter-clockwise) true means "counter-clockwise
