I have seen several questions which appear to be similar to mine, but I can't see an answer that gives what I need. I am not interested in adding dimensions to my drawing.

I inserted a reference image (aerial photo) and traced to relevant outlines that I wanted, then deleted the reference image.  I couldn't get to grips with the scaling options when I loaded the reference image, so the resultant lines are not the correct length (as shown by the 'properties' section).

How can I change the scale such that a line which now shows as 6.7 long will show as 57 and pro rata for all other lengths? I have seen how, if I added a dimension, it would show 57 instead of 6.7 but the properties sill show the line as 6.7, which is not what I want.

Can anyone help please?
