To Convert a Mesh Object to a 3D Solid

1. At the Command prompt, enter SMOOTHMESHCONVERT and specify one of the following conversion options:
   • Smooth, optimized. The resulting model is smoothed, with merged faces (SMOOTHMESHCONVERT = 0).
   • Smooth, not optimized. The resulting model is smooth, with the same number of faces as the original mesh object (SMOOTHMESHCONVERT = 1).
   • Faceted, optimized. The resulting model is angular, with merged, planar faces (SMOOTHMESHCONVERT = 2).
   • Faceted, not optimized. The resulting model is angular, with the same number of faces as the original mesh object (SMOOTHMESHCONVERT = 3).
2. Click Modeling tab > Solid panel > Convert to Solid.
3. Select a mesh object that has no gaps or intersecting faces.
