Transform |
An affine transform of 1D Euclidean space.
Inheritance HierarchyNamespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
SyntaxThe 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.).
