Conversion using this level will result in an axis aligned box (bounding box) that fully encloses the input body. One axis aligned box will be created for each input body. Using this level, the converted geometry will be the coarsest, and the model will have the least number of components. Using this level, the conversion to Icepak and the meshing in Icepak will be fastest. However, geometric details will be ignored. It is suitable for CAD parts that are already axis aligned Parallelepiped, or whose details are not important. Level 0 simplification does not provide any other options.
