Get error message when try to run code aeccDoc.Surfaces (aeccDoc = AeccDocument)

Hi everyone,

I'm trying to create tin surface from LandXml file by using IAeccSurfaces Interface.

(https://adndevblog.typepad.com/infrastructure/2012/12/creating-a-tin-surface-from-landxml-file.html)

But I got the error message in row "Autodesk.AECC.Interop.Land.AeccSurfaces oAeccSurfaces = aeccDoc.Surfaces;"

How can I fix this problem?

Or Is there any other way I can create TinSurface from file LandXml ?

Thanks everyone.

Which release of Civil 3D are you coding for? Do you really need to be using the COM API? There is now a .NET API method to create a TinSurface from a LandXML file.

You have to change this line:

string sAppName = "AeccXUiLand.AeccApplication.10.0"; // Civil 3D 2013

to match the version of Civil 3D you are using.

I'd suggest using the method Jeff shows here to never have to use the string again:

I'm working with Civil3d 2020 and Civil3d 2021.

No, I don't. I can not find that method in .NET API ... so I have to use the method in COM API.
Could you please send me the .NET API method to create a TinSurface from a LandXML file?

Thank you.
