Extraction of data in CAD

Hi

can any one explain how can we create a powerpoint or excel sheets from autocad

Those are two different programs so the approach to each might be a little different.

So your first question might be "How do I create a Powerpoint presentation using AutoCAD drawings?" And your second question might be "How do I link Excel and AutoCAD?" Am I on the right tract?

Exactly.

Linking Excel and AutoCAD:

The above four links should get you started. If you have further questions then come back and post them individually. By that I mean, keep questions related to either program, PowerPoint and Excel, separate so as to avoid confusion and maintain a nice flow of information. Agreed?

Thanks it will help
