Assigns elevations from surface.

Compute FingerPrint of the Entity.

Creates a FeatureLine from the specified Line, Arc, Polyline, Polyline2d or Polyline3d.

Creates a FeatureLine from the specified Line, Arc, Polyline, Polyline2d or Polyline3d.

Deletes an elevation point along the FeatureLine.

Deletes elevation points along the FeatureLine.

Deletes a PI point along the FeatureLine.

Gets the 3d distance at given point along the FeatureLine.

Gets the bulge at the index of feature line's segment.

Gets the radius at the index of feature line's curve.

Gets the deflection angle in radians at given point along the FeatureLine.

Gets the in grade at given point along the FeatureLine.

Gets the out grade at given point along the FeatureLine.

Returns the point's elevation, depending on the absolute or relative mode. Use the IsElevationRelativeToSurface() method to determine the elevation type.

Gets the feature line points by type.

For Data Shortcut reference entity (IsReferenceObject == true), gets the entity's reference information.

Inserts an elevation point along the FeatureLine.

Inserts multiple elevation points along the FeatureLine.

Inserts a PI point along the FeatureLine.

Gets whether the point's elevation is absolute, or relative to the surface. Returns true when it's relative to the surface, false when it's an absolute elevation.

Move FeatureLine to none Site.

Move FeatureLine to another Site.

Sets the bulge at the index of feature line's segment.

Sets the radius at the index of feature line's curve.

Set an elevation to existing Feature Point.

Sets a point's elevtion, with the elevation value specified either as an absolute elevation, or a relative to surface elevation.

Gets the Application. Not currently implemented.

Gets the FeatureLine's curve count.

Gets or sets the Entity object's description.

Gets the Entity object's display name.

Gets the Document. Not currently implemented.

Gets the FeatureLine's Elevation Points count.

Gets or sets FingerPrint of the Entity.

Gets the folder ObjectId of the Entity Returns ObjectId::Null if the Entity is located in root folder

Gets the value indicates whether the Feature derived entity (Alignment,Profile,etc) is editable.

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.

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.

For reference objects (IsReferenceObject == true), gets whether the Entity object's reference is stale.

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.

For reference objects (IsReferenceObject == true), gets whether the Entity object's reference is valid.

Gets whether the style is used by other objects in the current drawing.

Gets the FeatureLine's 2D length.

Gets the FeatureLine's 3D length.

Gets the FeatureLine's maximum elevation.

Gets the FeatureLine's maximum grade.

Gets the FeatureLine's minimal elevation.

Gets the FeatureLine's minimal grade.

Gets or sets the Entity object's name.

Gets the FeatureLine's PI Points count.

Gets the FeatureLine's points count, including PI Points and Elevation Points.

Gets or sets the Featureline's relative surface Id.

Gets or sets whether to show tooltips for the Entity.

Gets the ObjectId of the Site which FeatureLine belongs to.

sets the FeatureLine's style Id.

Gets or sets the Featureline's style name.
