The frames are in the center of the line set, second from the right...
Here they are pulled from the set, and in the second picture I have highlighted them in red.
The left side are the frames from the mid ship to the stern.
And the right side of the drawing is the midship to the bow.
The outside frames reuse the outer most line, for the two lowest/largest lines on each side.
Photo copy that area of your plans once, for each frame you need.
Then take each copy, fold it in half, and cut along one frame line, and then
. boldy number it with the number of the frame line you cut.
You should end up with a cut piece of paper for each frame line. And when unfolded, it will
represent the cross section of the boat at that frame.
You can than mount the paper cutouts to plywood and proceed to cut your frames.
Don't forget to allow a "bump" or an area of plywood at the center to allow you to
make a cut out to place the frame over a keel.
