OK then.  I looked at the GCAM program site without installing it yet. 
Seems to have a 3D wireframe view of "hand made" macros done via GUI to 
create sets of RS-274 G codes.  The G code macros it will make are about 
cutting simple circle or rectangle shapes, then outputting a series of 
moves that will cut a global depth of cut setting and repeat while 
necessary.  I did not see anything generating spline curves yet.

I cannot find any import export function yet.

So far, Blender -->python scripts to create G codes --> GCAM setup 
details added to G codes --> machining job shop  is the most reasonable 
flow I have found to make real parts with.  It might be possible to go 
from blender --> STL --??--> IGES, but I've not found how yet.

GCAM checked G codes are farther along than an IGES file, so your 
charges at the machine shop would be less with them.

Whether GCAM would show in 3D a set of G codes that follow a spline 
curved surface from Blender is an interesting question to answer...
