Can anyone assist me with this? Kind of take these numbers and draw out a frame on paper for an example?
I am attaching Stern lofting numbers. On my Y axis, I have the heights of my frame and x axis would be width. What is my line spacing? For example 6"? Can someone take these numbers and draw out an example frame?

Don't see any attachment??? What numbers do you have? Sorry if you've mentioned it before but which boat is this for?fishgitr wrote: ↑Fri Aug 16, 2024 4:32 pm Can anyone assist me with this? Kind of take these numbers and draw out a frame on paper for an example?

Usually the plans will specify the spacing between stations (e.g in Jacques' notation for my build it states "24" typ" in one single place on the plans - and that is on a different sheet to where some of the "parts" are shown laid out with offsets). The plans also state, on one page or another, how many stations there are, and where the baseline is. The numbers are measurement points from the baseline, usually in the vertical direction.
The numbers and baseline you need might not be on the same page as the offsets. Naval architects usually put each necessary measurement in just one place on the plans (perhaps on a different sheet). This is for convenience, and to minimise error, so that if they change anything, it is only changed in one place also.
When I started building it took me quite a while to figure out everything. I printed out the pdfs many times and added multiple annotations of my own to help when I was laying out...
If someone else has already built your design, I'm sure they will chime in and offer comments.
Good luck and keep posting on progress!

Re: Lofting
Your numbers should be left and right from a vertical center line , and up and down from a center line , or top or bottom line or starting point . Put a mark on each point , example 30" left 20" up , when you have finished marking your frame drive a finish nail into each point , take a 1/2" piece of hot water pvc pipe or small dia hard flexible item that will bend around the nails . Bend the pipe around the nails , put nails to whichever side of the pipe you need to to hold the pipe tight to your nails on your points , trace along the pipe from point to point .
