okay,
heres a quarter of one image (A4 size), it's a plan of a stone circle - I've overlaid a heavy grid for clarity here, also tried to choose an area that wasn't too cluttered with stones
If you think it's not too bad,
keep in mind it's a quarter of one image that's supposed to join up with four other A4 images to make one large drawing.
Also, it's at a scale of 1 to 100 so if it's one mm out thats multiplied by 100 ..
Note: they were drawn in the field this way, notebook-paper is already distorted from years of heated room to cold humidity & back, then photocopied & sent to me & I scan it - I know there must be a better way but thats the way it's happening for the foreseeable future.
Also, across 297mm (A4 page height) you can get a lot of wobbeldy bits going in various directions on one line

It would be nice though, to be able to photograph a really large drawing & know you could correct it later.
I was working on some over 6 foot drawings a couple of years ago but that was all done by hand
EDIT:
PS. these are screenshots & so not to scale!
