| Line Members |
| Line Class Methods Properties See Also |
The Line type exposes the following members.
Methods
| Name | Description | |
|---|---|---|
 | Clone | Returns a copy of this curve. (Inherited from Curve.) |
| ComputeClosestPoints |
Find the closest points between two curves.
Closest points mean closest pairs of points, each pair consisting of a point on this, say P1, and a point on other curve, say P2.
P1 and P2 are closest locally.
Each pairs of closest points will be represented by the corresponding parameter values with respect to the two curves and the 3d points.
A closest pair is also known as a pair of critical points of the distance function between points of the two curves.
If the input parameter returnAllCriticalPoints is set to false, then the function will return only pairs with minimum distance.
(Inherited from Curve.) |
| ComputeDerivatives |
Returns the vectors describing the curve at the specified parameter.
(Inherited from Curve.) |
| ComputeNormalizedParameter | Computes the normalized curve parameter from the raw parameter. (Inherited from Curve.) |
| ComputeRawParameter | Computes the raw parameter from the normalized parameter. (Inherited from Curve.) |
 | CreateBound |
Creates a new instance of a bound linear curve.
|
| CreateOffset |
Creates a new curve that is an offset of the existing curve.
(Inherited from Curve.) |
| CreateReversed |
Creates a new curve with the opposite orientation of the existing curve.
(Inherited from Curve.) |
| CreateTransformed |
Crates a new instance of a curve as a transformation of this curve.
(Inherited from Curve.) |
| CreateUnbound |
Creates a new instance of an unbound linear curve.
|
| Dispose | Causes the object to release immediately any resources it may be utilizing. (Inherited from APIObject.) |
| Distance | Returns the shortest distance from the specified point to this curve. (Inherited from Curve.) |
| Equals | (Inherited from GeometryObject.) |
| Evaluate |
Evaluates and returns the point that matches a parameter along the curve.
(Inherited from Curve.) |
| GetEndParameter |
Returns the raw parameter value at the start or end of this curve.
(Inherited from Curve.) |
| GetEndPoint |
Returns the 3D point at the start or end of this curve.
(Inherited from Curve.) |
| GetEndPointReference | Returns a stable reference to the start point or the end point of the curve. (Inherited from Curve.) |

| Intersect(Curve) | Calculates the intersection of this curve with the specified curve. (Inherited from Curve.) |
| Intersect(Curve, IntersectionResultArray%) | Calculates the intersection of this curve with the specified curve and returns the intersection results. (Inherited from Curve.) |
| IsInside(Double) | Indicates whether the specified parameter value is within this curve's bounds. (Inherited from Curve.) |
| IsInside(Double, Int32%) | Indicates whether the specified parameter value is within this curve's bounds and outputs the end index. (Inherited from Curve.) |
| MakeBound | Changes the bounds of this curve to the specified values. (Inherited from Curve.) |
| MakeUnbound | Makes this curve unbound. (Inherited from Curve.) |
| Project | Projects the specified point on this curve. (Inherited from Curve.) |
| SetGraphicsStyleId | Sets the graphics style id for this curve. (Inherited from Curve.) |
| Tessellate | Valid only if the curve is bound. Returns a polyline approximation to the curve.
