Syntax

C#

public class Transform1D : IDisposable

The Transform1D type exposes the following members.

Constructors

	Name	Description
	Transform1D(Double)	Constructs the transformation by specifying the scale only.
	Transform1D(Transform1D)	The copy constructor.
	Transform1D(Double, Double)	Constructs the transformation by specifying the scale and the translation.

Properties

	Name	Description
	Determinant	The determinant of this transformation.
	IsIdentity	The boolean value that indicates whether this transformation is an identity.
	IsValidObject	Specifies whether the .NET object represents a valid Revit entity.
	Scale	The real number that represents the scale of this transformation.
	Translation	The translational part of this transformation.

Methods

	Name	Description
	AlmostEqual	Determines whether this transformation and the specified transformation are the same within the tolerance (1.0e-09).
	Assign	Assigns values from the input transformation to this transformation.
	Dispose	Releases all resources used by the Transform1D
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
	GetHashCode	Serves as the default hash function. (Inherited from Object)
	GetInverse	Gets the inverse transformation of this transformation.
	GetType	Gets the Type of the current instance. (Inherited from Object)
	Multiply	Multiplies this transformation by the specified transformation and returns the result.
	OfPoint	Applies the transformation to the 1-dimensional point and returns the result.
	OfVector	Applies the transformation to the 1-dimensional vector (a "tangent vector" on the real line) and returns the result.
	SetToIdentity	Set this TrfUV to the identity transform
	ToString	Returns a string that represents the current object. (Inherited from Object)
	TransformParameterDomain	Performs a transform of the parameter range defined by domain, and ensures that the domain is ordered correctly.

Remarks

An affine transform is a linear transform plus a translation (which may be zero). 1D space is tranformed according to the following formula: t -> A*t + B where A and B are constants. Some functions only accept certain kinds of transform (e.g., rigid motion, conformal, non-singular, etc.).
