A corridor feature line is a connected series of points along a corridor created by joining those points from each assembly that share a particular code. Feature lines are used to build the 3D model of a corridor.

SyntaxThe AutoFeatureLine type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | AlignmentId | Gets the Alignment Id |
| Application |
Gets the Application. Not currently implemented.
(Inherited from Entity) |
| AutomaticUpdate | Gets/sets the status of the automatic update property |
| CurvesCount |
Gets the FeatureLine's curve count.
(Inherited from FeatureLine) |
| Description |
Gets or sets the Entity object's description.
(Inherited from Entity) |
| DisplayName |
Gets the Entity object's display name.
(Inherited from Entity) |
| Document |
Gets the Document. Not currently implemented.
(Inherited from Entity) |
| ElevationPointsCount |
Gets the FeatureLine's Elevation Points count.
(Inherited from FeatureLine) |
| FingerPrint |
Gets or sets FingerPrint of the Entity.
(Inherited from Entity) |
| FolderId |
Gets the folder ObjectId of the Entity
Returns ObjectId::Null if the Entity is located in root folder
(Inherited from Entity) |
| IsCWSReferenceObject |
Gets whether the Entity is a Civil Worksharing reference object. A Civil Worksharing reference object is
a Civil object shared to Shared Space. It is not editable. But it can be updated to the new version in the Shared Space.
(Inherited from Entity) |
| IsCWSSourceObject |
Gets whether the Entity is a Civil Worksharing source object. A Civil Worksharing source object is
a Civil object shared to Shared Space. It is editable and can be updated to Shared Space.
(Inherited from Entity) |
| IsEditable |
Gets the value indicates whether the Feature derived entity (Alignment,Profile,etc) is editable.
(Inherited from Feature) |
| IsPartialReferenceObject |
Gets whether the surface is partial reference surface.
(Inherited from Entity) |
| IsReadOnlyReferenceObject |
Gets whether the Entity is a readonly reference object. A readonly reference object is
either a data shortcut referece object or a Civil Worksharing reference object.
(Inherited from Entity) |
 | IsReferencedSourceExisting |
For reference object (IsReferenceObject == true), it will try to get its source entity while opening a drawing.
This indicates whether the reference object has source entity.
(Inherited from Entity) |
| IsReferenceObject |
Gets whether the Entity is a reference object. A reference object is
located in another drawing, and linked using a data shortcut or Vault.
If the entity is native to the current drawing this property returns false;
if it is being referenced via data shortcuts or AutoCAD Vault it returns true.
(Inherited from Entity) |
| IsReferenceStale |
For reference objects (IsReferenceObject == true), gets whether the Entity object's reference is stale.
(Inherited from Entity) |
| IsReferenceSubObject |
For reference objects (IsReferenceObject == true), gets whether the Entity is a reference subobject.
For example, when iterating through the structure of a pipe network referenced from another drawing,
this property is true for each entity.
(Inherited from Entity) |
| IsReferenceValid |
For reference objects (IsReferenceObject == true), gets whether the Entity object's reference is valid.
(Inherited from Entity) |
| IsUsed |
Gets whether the style is used by other objects in the current drawing.
(Inherited from Entity) |
| Length2D |
Gets the FeatureLine's 2D length.
(Inherited from FeatureLine) |
| Length3D |
Gets the FeatureLine's 3D length.
(Inherited from FeatureLine) |
| MaxElevation |
Gets the FeatureLine's maximum elevation.
(Inherited from FeatureLine) |
| MaxGrade |
Gets the FeatureLine's maximum grade.
(Inherited from FeatureLine) |
| MinElevation |
Gets the FeatureLine's minimal elevation.
(Inherited from FeatureLine) |
| MinGrade |
Gets the FeatureLine's minimal grade.
(Inherited from FeatureLine) |
| Name |
Gets or sets the Entity object's name.
(Inherited from Entity) |
| PIPointsCount |
Gets the FeatureLine's PI Points count.
(Inherited from FeatureLine) |
| PointsCount |
Gets the FeatureLine's points count, including PI Points and Elevation Points.
(Inherited from FeatureLine) |
| ProfileId | Gets or sets the Profile Id |
| RelativeSurfaceId |
Gets or sets the Featureline's relative surface Id.
(Inherited from FeatureLine) |
| ShowToolTip |
Gets or sets whether to show tooltips for the Entity.
(Inherited from Entity) |
| SiteId |
Gets the ObjectId of the Site which FeatureLine belongs to.
(Inherited from FeatureLine) |
| SourceObjectId | Gets or sets the Source ObjectId. this returns the same value as the AlignmentId property |
| SourceObjectName | Returns the source object name |
| SpiralTessellation | Gets/sets the spiral tessellation |
| StyleId |
sets the FeatureLine's style Id.
(Inherited from FeatureLine) |
| StyleName |
Gets or sets the Featureline's style name.
(Inherited from FeatureLine) |
| VerticalDeviation | Gets/sets the vertical deviation |
Methods| Name | Description | |

| ComputeFingerPrint |
Compute FingerPrint of the Entity.
(Inherited from Entity) |
| DeleteElevationPoint |
Deletes an elevation point along the FeatureLine.
(Inherited from FeatureLine) |
| DeleteElevationPoints |
Deletes elevation points along the FeatureLine.
(Inherited from FeatureLine) |
| DeletePIPoint |
Deletes a PI point along the FeatureLine.
(Inherited from FeatureLine) |
