Removing Surface Breaklines using AutoCAD Civil 3D API

By Partha Sarkar

AutoCAD Civil 3D COM API has IAeccSurfaceBreaklines:: Remove method to remove Surface Breaklines. In the ‘ActiveX API Reference’ document we see this  –

IAeccSurfaceBreaklines:: Remove Method - > Removes an item from the collection, specified by index or object reference.

HRESULT Remove( [in] VARIANT varIndex);

One of our Civil 3D application developers friend recently asked me ‘how do we use object reference in Remove()’ ? That prompted me to dig deeper in this and I find we can only use index in the Remove() and it doesn’t work with object reference. By the time we update the Civil 3D ActiveX API reference document on this, I thought it would be useful to you all if I share this information here in IM DevBlog.

Here is the VB.NET code snippet showing usage of COM API Remove(index) –

If(oTinSurface.Breaklines.Count > 0)

 

  ' Remove() Breakline using COM API

  oTinSurface.Breaklines.Remove(0)

  oTinSurface.Rebuild()

  ed.WriteMessage(vbCrLf + "Breakline Removed ! " )

 

End If

 

In Civil 3D .NET API we have the equivalent RemoveAt(int) and here is C# .NET code snippet –

// Get the TIN Surface       

TinSurface tinSurface = surfaceId.GetObject(OpenMode.ForWrite) as TinSurface;

 

// Lets try to Remove Breakline using RemoveAt(int)       

  tinSurface.BreaklinesDefinition.RemoveAt(0);

 

// rebuild the surface

  tinSurface.Rebuild();

 

Hope this is useful to you!
