How you can generate 4-axis toolpath for HUGE facet body (imported STL, 320 Mb binary file)? Just see a video!! I build one UGOPEN application to UNWRAP "cylindrical" STL to "PLANAR" STL, I do it without import STL into NX, just working with input file and output new unwrapped stl to another file and after this recalculation - import STL to NX. Then - generate 3 axis FIXED CONTOUR operation. And - WRAP this toolpath to source STL. Thats all.
