Hello @RAJENEESHMISHRA
You will probably find the information you are looking for in URLs (expecially the second one, but it's not PDF) provided in article 118858
In order to go deeper in technical details, you will also have a better understanding of what offers Advanced Assembly Extension, akas AAX (compared to what is offered by Pro Assembly module) starting from article 58879. (also not a PDF, but PDF easily possible with >File >Print and using a virtual printer, like PDF Creator or Microsoft Print to PDF).
Hope this helps,
Regards,
Serge
