TurboCAD CAM 2.5 dim or 3 Dim ?

Guys,

Turbo CAD CAM seems like a great G code generator with calculators etc.

Howewever, I have tried to select a 3D object in .TCW and .SAT but I
have not been sucessful. Does anyone know if this package can take as
input 3D from .TCW, .DXF, .SAT or other popular format files ? Or is it
simply a 2.5D package that cannot use parts already made.

As a last resort, is there a way to convert the 3D parts from the
popular formats to 2D and depth that can be used as input?

Thanks
