Namespace: Autodesk.Civil.DatabaseServices

Syntax

C#

public SurfaceOperationAddBreakline[] ImportBreaklinesFromFile(
	string filename
)

Visual Basic

Public Function ImportBreaklinesFromFile ( _
	filename As String _
) As SurfaceOperationAddBreakline()

Visual C++

public:
array<SurfaceOperationAddBreakline^>^ ImportBreaklinesFromFile(
	String^ filename
)

Parameters

filename: Type: System.String
The path and name of the file used to create the breaklines.

All breaklines in the FLT file are copied into the surface as Add SurfaceOperationAddBreakline operations. After the import, the FLT file is no longer referenced. If you want to maintain the link, use AddBreaklinesFromFile().
