Hi everyone. I have to draw up a streetscape for a planning application and was just wondering is there a program you can download to convert a jpeg to a dwg/dxf file in autocad. Great site by the way.

I think you can import images to attach to an existing .dwg but I don't think there's a way of extracting the raw image data for manipulation or anything.

Some people xref in the image and trace over it like for building profiles and what not

Its an issue I quite often face, and I have yet to find any software that will convery JPEG directly into .DWG. If the JPEG has any dimension marked on it, or anything that has a known dimension, then it can be imported into Autocad or a whole number of other CAD apps as a picture and then expanded or reduced to the drawing scale and then, as suggested above, traced over. It's not a dead accurate way of doing it though since JPEG doesn't produce sharp lines.

I've tried it and it works:)
I don't know if it helps the originator of the post, but it does help me. Many thanks.

Thats not going to help in my opinion,
Its a raster to vector convertor, so it can take a rastered "line drawings" and make a vector drawing from it.
It won't work well with a photographic, as there is no line data to vectorise.

As an aside, one example often used is PDF, which is a bit silly as a PDF is a vector drawing already (unless scanned)

This will do PDF to DWG/DXF while not free it does work.

EDIT: Just noticed it's incredibly expensive!

I think there is a way to do PDF to DWG with pretty standard office software.
A pdf is already a vector drawing

Nice one Sinnerboy... Aide PDF to DXF, thats pretty good quality. Better than the others I've tried.
