Michael:
When I was looking for plans to make a Taylor 12 style, what I ended up doing was to go to the Taylor website, drag a JPG photo (tiny) of their bracing scheme from this page:
http://www.taylorguitars.com/guitars/features/bracing/Types.aspx, and then copy the specs from the "Show complete specs" pull-down menu on the Taylor 12 model page. (Here's the page for your 314ce model:
http://www.taylorguitars.com/Guitars/Acoustic-Electric/300/314ce/)
What I did with the tiny JPG photo was enlarge it to a full page size, then draw a grid over it so I could then make a full-size plan. The complete specs list gave me a few other measurements to go by.
I also went to a local guitar store and asked them if I could trace the body shape of a Taylor, so I could figure out the cutaway shape, especially.
It was a bit of work to do all this, but it worked out okay. You can see how mine turned out on this page:

Hope this helps.
