Methods| Name | Description | |
|---|---|---|
| AssignElevationsFromSurface |
Assigns elevations from surface.
(Inherited from FeatureLine) |
| ComputeFingerPrint |

(Inherited from Entity) |
| DeleteElevationPoint |
Deletes an elevation point along the FeatureLine.
(Inherited from FeatureLine) |
| DeleteElevationPoints |
Deletes elevation points along the FeatureLine.
(Inherited from FeatureLine) |

| DetachCorridor | Detaches the corrioor from the auto corridor feature line |
| ExtendWithFixedCurve(Boolean, Point3d) |
Extends the feature line with a curved arc segment to the specified target point.
This method adds a new fixed arc segment to either the beginning or end of the feature line,
creating a smooth curve from the current start/end point to the specified target point.
The arc is automatically calculated based on the current tangent direction and target point.
The method determines the optimal arc geometry to create a smooth transition.
(Inherited from FeatureLine) |
| ExtendWithFixedCurve(Boolean, Point3d, Point3d) |
Extends the feature line with a curved arc segment defined by three points.
This method adds a new fixed arc segment to either the beginning or end of the feature line,
creating a smooth curve that passes through the specified second point and ends at the target point.
The arc is calculated using the three-point arc definition method, providing precise control
over the arc's curvature and direction. This is useful when you need to create arcs with
specific geometric constraints.
(Inherited from FeatureLine) |
| ExtendWithFixedLine(Boolean, Point3d) |
Extends the feature line with a straight line segment to the specified target point.
This method adds a new fixed linear segment to either the beginning or end of the feature line,
connecting the current start/end point to the specified target point.
The extension creates a fixed line segment that becomes part of the feature line's geometry.
This is useful for extending feature lines to specific coordinates or connecting to other objects.
(Inherited from FeatureLine) |
| ExtendWithFixedLine(Boolean, Double) |
Extends the feature line with a straight line segment of specified length.
This method adds a new fixed linear segment to either the beginning or end of the feature line,
extending in the current direction by the specified distance.
The extension direction is determined by the tangent direction at the start or end point.
For smoothed feature lines, the extension follows the smoothed curve's tangent direction.

| GetGradeOutAtPoint |
Gets the out grade at given point along the FeatureLine.

Returns true when it's relative to the surface, false when it's an absolute elevation.
(Inherited from FeatureLine) |
| ReAttachCorridor | Reattaches the corridor the the auto corridor feature line |
| Reverse |
Reverses the direction of the feature line (start and end swap; curve parameterization is reversed).
