Extracting DATA from AutoCAD using ObjectARX

[Anonymous]

Hi everybody.
Well I am starting to work on a new project where I need to extract information from an dwg file.
I understand that this can get quite requirement specific. However my question is really basic.
What are the steps I should follow here?
If somebody can get me started with an example like where I can extract the co-ordinates of a line and the length then I guess I can get on with it.
Please let me know what you guys got to say.
Thanks in advance.

Hi,
Firstly, you should choose the right SDK(ObjectARX, ObjectDBX, RealDWG)
according to your requirement. Then get the SDK and read the help files and
documentation. After that, you will have a general idea about the question
you mentioned.

RealDWG is what ObjectDBX used to be called, they are the same thing.
"Choosing" ObjectARX is easy because all you need is AutoCAD, RealDWG must
be specifically licensed.

Thanks for your interest in this guys.
I'll probably use ObjectARX because I am familiar with it.
But I have a small problem which I think one of you can solve.
I want to find out how to get the length of a polyline from a drawing using ObjectARX when the user selects the polyline. If somebody can get me started with some code then it probably put me on the right track. Please let me know how this can be accomplished.
Thanks in advance
