What is the difference between .NET API and ObjectARX API?

[Anonymous]

I need to dump the coordinates of alignment and profile, but I cannot found the reference of the command list of both of .NET API and ObjectARX API. I have some questions and will appreciate if anyone can give me some advice about them.

1 Where can I find the reference of the commands?

2 Do .NET API and ObjectARX API both provide the commands to access the coordinates alignment and profile?

3 What is the difference between them? I mean the complexity and time to learn.

4 To access coordinates or dump coordinates to a text file, which one is easier to code?

5 Do they provide the commands to write data into a text file? Or can I use standard i/o in visual studio?

Press F1 in Civil 3D and in the contents look for Developer Help.

2 Do .NET API and ObjectARX API both provide the commands to access the coordinates alignment and profile?

I'd do .NET, ObjectARX is C++ based and I haven't attempted to program in it.

3 What is the difference between them? I mean the complexity and time to learn.

Due to advances in programming c#.NET is easier to learn and use.

4 To access coordinates or dump coordinates to a text file, which one is easier to code?

Look at the reports source code that comes with the program: C:\ProgramData\Autodesk\C3D 2011\enu\Data\Reports\Net\Source One of the reports dumps to a file (html, doc, xls) or can easily be modified to a text file.

5 Do they provide the commands to write data into a text file? Or can I use standard i/o in visual studio?

You can use the standard i/o in visual studio.
