.srf (surfcad) to .s3dx (shape3d)

Hey friends, I’m trying to convert some files from surfcad to shape3d. I’ve tried akushaper, boardcad and shape3d. These softwares can open the .srf file but some curves are wrong. Anyone know a tip to convert the file and see exactly the same board as in surfcad?

Thank you guys for all the support!
