A two decade ago nobody would have thought, whatever we draw manually on paper can be drawn on computer more accurately, with exact measurement, precisely in a much faster mode.
AutoCAD from AutoDesk has got all the above. I personally know many designing and drafting softwares like Microstation, Autodesk Inventor, PDS, PDMS, SPR, RR, Elecdes, Paneldes etc. Among all I would rate AutoCAD as the best designing and drafting package.
Generally all the software has got some boundaries/limitations. But AutoCAD is so user friendly and flexible that just with help files & practice you can master it. And so far with my experience it has no area where you stuck, hardly you have to debug it or improper closing required.
I am not a seller but a genuine user. I am confident I can change any entire design office from manual to Computerized only with the help of AutoCAD, this assurance no other software can challenge it in short span.
If you are planing for design office or even personal use like Plan of your house, buisness, electrical, mechanical, piping, civil, architectural layouts etc. go ahead and purchase AutoCAD from an authorized AutoCAD dealer, It is worth of money I assure you.
