Finally figured out how to implement multiscale calculation in Autodesk Inventor, thanks to cross-checking scale lengths between DXF and SVG format.
FretFind's DXF output for fanned frets really threw me for a loop, since the frets looked like this:
After many days of frustration, I realized that SVG and DXF output was correct, the SVG's frets are not colinear after all (due to non-vertical string paths),
and that simply joining the scales of the outer string paths would produce negligible intonation errors (on the order of microns!).
Though in the end I really had nothing to worry about, I figured I might share my experience with FretFind2D so others won't get caught in the non-issues that I tried to solve!
