SW ScanTo3D can not yet import CT data format directly but if they could convert it to Cloud point or mesh on their end, then it's a good change that SW could read it. ScanTo3D formats are:
Mesh: nzip, nxm, scn, 3ds, obj, stl wrl, ply ply2 (first three are Next engine formats)
Cloud Point: xyz, txt, asc, vda, igs, IBL
Thanks for the link, that might prove useful!
