OdPrcHelixType0Curve Class

Class Hierarchy

Syntax

C++

class OdPrcHelixType0Curve : public OdPrcCurve3d;

File

PrcHelixType0Curve.h

Description

Class implements a helix with a constant pitch. A helix is a three-dimensional curve defined on an [-infinite, infinite] interval. A helix can be parameterized and transformed for positioning in model space.

Remarks

Transformation can be one of the following:

Value Description

0x00 Identity

0x01 Translate

0x02 Rotate

0x08 Scale

OdPrcHelixType0Curve inherits the OdPrcCurve class and can be reparameterized and trimmed using the OdPrcParameterization class and setParameterization() method.

OdPrcCurve Methods

	Name	Description
	contentCurve	This is the overview for the contentCurve method overload.
	is3d	Returns the current curve's 3D flag value. The flag is equal to true if the curve is a 3D object or is equal to false in the other case.
	parameterization	Returns the current parameterization information used for the curve.
	read	Reads curve data from a specified input stream, and creates and returns a curve entity.
	readArray	Reads data from a specified input stream into a curve array.
	readPtr	Reads curve data from a specified input stream, creates a curve, and returns a smart pointer to an OdPrcCurve object.
	setParameterization	Sets new parametrization information to the curve.
	writeArray	Writes data from a curve array to a specified output stream.
	writePtr	Writes curve data to a specified output stream.

OdPrcCurve3d Class

	Name	Description
	createFromOdGeCurve	Creates new 3d curve instance from OdGeCurve3d.
	getGeMatrix3d	Returns the current transformation matrix for the curve.
	getOdGeCurve	Returns the current curve data.
	is3d	Returns the current curve's 3D flag value. The flag is equal to true if curve is a 3D object or is equal to false in the other case.
	setFromOdGeCurve	Sets a new instance of the curve data.
	setTransformation	Sets a new transformation for the curve.
	transformation	Returns the current transformation for the curve.

OdPrcHelixType0Curve Class

	Name	Description
	direction	This is the overview for the direction method overload.
	origin	This is the overview for the origin method overload.
	pitch	Returns the current value of the helix pitch.
	radiusEvolution	Returns the current value of the radius evolution of the helix.
	setPitch	Sets a new value of the helix pitch.
	setRadiusEvolution	Sets a new value of the radius evolution of the helix.
	setTrigonometricOrientation	Sets the trigonometric orientation flag. The trigonometric orientation flag determines the turn direction of the helix. If the flag is set to true, the helix turns in the clockwise direction; if the flag is set to false, it turns in the counter-clockwise direction.
	start	This is the overview for the start method overload.
	trigonometricOrientation	Returns the current value of the trigonometric orientation flag. The trigonometric orientation flag determines the turn direction of the helix. If the flag is set to true, the helix turns in the clockwise direction; if the flag is set to false, it turns in the counter-clockwise direction.
