For most of the fuselage I am slicing it up into 95mm sections (100mm foam sheet less a surface skim). Fusion will output a drawing of each end of the slice for the foam cutter. Of course it is not as simple as that as the drawings need processing into the right format for the CNC foam cutter. This has been a learning curve too, but with the help of a few people in Germany and France I have it sorted. For each section 2 files are needed, one for each end. Fusion outputs these drawings which are a series of curves and straight lines. I open each one in Autocad and break the curves down into a series of short straight lines (this is automated). These get rejoined into a single multiline which is the path for the hot wire to follow. This drawing then gets converted (Profscan) into a data file that the CNC machine understands. However as each foam slice has a different drawing for each end they need further processing to make each end have the same number of line segments. This is a clever custom program called Echantillonnage it is in French so there was a fair bit of Google translate going on to learn it. The 2 files are then imported into the foam cutting program (GMFC) aligned and sized correctly then cutting can commence.
Here is a test piece but will end up as a 4 degree wedge at the tail post.
