Curious- in your thumbnail, the top left, bottom left and bottom right drawings are just lines (not shaded). How did you do that? Wasn't covered in the video, I think.
I am a home hack making mostly small parts and would like to use the drawing to make paper templets to glue onto material to make . the 1:1 scale does not print full size a 100 mm dimension comes out at 97mm so it is useless to me. Is there a way to correct this?
