hi,
hope you all are fine..
today client send me one drawing which is on jpep file format so i want
to convert that file into autocad so can you people refer me some go0d
converting software....

You can't convert a photo (raster-based image file) into a drawing (vector-based file).  You can import an image (raster file) into a drawing and trace it, but there's no way to do a straight conversion.  They are simply two different types of files.  Apples and oranges.Dave.

There are many programs out there that purport to do that.  I haven't used them, so I don't know how well they succeed, but put "raster to vector conversion software" into a web search, and you'll find lots of offerings.  I couldn't say whether any are outright free, but some [e.g. one called Scan2Cad] at least have free trials so you can check them out before you spend money on them.

Try a search on raster to vector conversion.

finally i m going to trace... :P :P :P

Trust me, we've all done it too. Dave.
