Is it possible to upload photo images into cad software

[FatFreddie]

Take a photo (long lens, make sure you're square on, have a contrasting background), use Inkscape, import the image and trace it (http://inkscape.org/doc/tracing/tutorial-tracing.html) then export as DXF and load into your favourite CAD package.

If you need sizes to be accurate, put a ruler or known size object in the photograph and resize to suit.

I've done that sort of thing before. Maybe put two rulers, perpendicular, to get the scale exactly right/stop it skewing.
