1. convert Dicom to STL use (mimics - magics - 3D doctor - inVesalius)
2. convert STL to solid model use ( solidworks - 3dmax)

Dear Hiba - if you're still looking for a solution to this problem, you might want to consider our software - we can convert DICOM to STL for export, and have options for creating NURBS models.
We can also generate volume meshes from CT with contact surfaces, node sets, shell elements, CFD boundary conditions, and material properties. Files can be exported in solver-specific formats, e.g. to ANSYS, COMSOL, Abaqus.
