Ways To Work Between 3D Program and Pepakura Program

    Originally we build the 3D model and send it out to Pepakura program for flat down the 3D model so we can export out to Rhinoceros 5 for laser cutting process. But since we got a Plotter we can totally send it out directly from Pepakura to Plotter  for printout. Question is "How" we set up the UV properly and import the texture in to Pepakura.
    In Pepakura, we have ability to layout the UV, which is the same way we lay out the piece as we sliced them in to the table. But first thing is make sure the Table is "Square Size!" This is very important, neither way of the  size of table or the size of the 3D model, but the table must stay on square size. Also you may turn off the flaps so there are are more spaces you can use to fit in the table the way you can figure out that which piece is which
Ex:

Once its has been layout, File>>Export>>Texture Editing>>Map Image for Texture,
by this process you will be export out a .bmp file and the program will reset the default UV to what we have layout as on top of the image.

    After reset the Model UV by export the bmp file, we can export the OBJ file from Pepakura
This obj file is going to drop in to Mudbox, which is what I use, for editing the texture from 3D surface. (At here I'm not going to teach how to work on Mudbox since so much totural video on YouTube.)
File>>Export>>Texture Editing>> 3D Model with UV Info

    As an ATEC student who have taking the Modeling class, Autodesk Mudbox is one of the suggest program to use for student. I only texture the upper body of the model so what happened to the texture is become like this

    The lower body is not texture so nothing is under the texture file.
The Pepakura3 do not have ability to import the texture over 1024px but the newer version Pepakura4 have ability to take the 4096px, so suggest to download Pepakura4 for the high quality resolution.
    The way to import the image to Pepakura is very basic, Setting>>Texture Setting>>Specific Texture Image>>select the image
Then go to Other>>Texture On/Off for turn on the texture.

Once done import the image, the 3D object should be colored on. Then you will need to re-placing the pieces since the Plotter's width is 3ft, which is totally different than what I have on above. So what I have done is to re-setting the table to 3ft width and test out the best way of placement and everything works out proper. At the end the quality is totally worth to do with.

Extra editing for plotter printing:
Padding

Also the place to change the size of padding is
Setting>>Other Setting>>Other>>Amount of Outline Padding
