JPG to 2-D Drawing

HI All,

I have some difficulty / question in converting a JPG file to 2-D drawing.

1. how can I make sure when creating a 2-D profile from the attached picutre, that it is in 1:1 scale?

2. The dimensions measured from the sketch I created from JPG file do not match the real dimensions of the original object (object -which i scanned).

Any help will be greatly appreciated.

Thank you,
