How to create a solid from a points file

I have a points file that I am trying to create a solid from. It is an xyz data list from a solid mesh (not a surface mesh). I have tried FE Modeller in Ansys with no luck because the surface is too complex even when I cut it into pieces. I am currently trying to use GeoMagic, but the wrap feature keeps shrinking my part. I believe this is due to my points cloud being solid and not surface. I have also tried Creo/Pro-E but don't have the reverse engineering extension plug in. Any help is appreciated.
