The slicing process dissects a three-dimensional part into two-and-a-half-dimensional slices. These are a collection of two-dimensional layers. The slice files are vital for manufacturing parts, as 3D-printing machines cannot read three-dimensional data.
Furthermore, slices provide you with a visualization of cross sections of your part, and you get more detailed information about the object. You also have the chance to edit your slices before fabricating them. Many of these functions are also available in the three-dimensional data management. However, in the Slice Commander, you have the advantage that calculations are performed much quicker, as complex 3D-tasks are replaced by 2D-tasks. This reduces the complexity of the data handling. For slices, there is an own section in the project tree, where all slices are organized in the same way as parts in the part section.
