Mathematica supports many popular file formats for 3D graphics, including the CAD-related "DXF" and LightWave 3D "LWO". As with other 3D graphics in Mathematica, these imported files can be rotated with a mouse or other input device.

Import a DXF example file, rendering it as a Graphics3D object:

Import an LWO example file:

Mathematica also allows you to export 3D graphics for use in other programs.

Create a plot in 3D and then export it:

Create a 3D contour plot and export it:

Export a 3D graphic imported from ExampleData:

Once exported, you can bring 3D graphics back into Mathematica.

Import the 3D graphic you just exported:
