The Structure tab enables you to show the structure of the part. By default, the tab only lists the components of the part calculation, but the preset 'Part structure' enables you to display any subparts as well. The tree structure clearly shows the composition of the part.

The column properties of the Structure tab match those on the List tab. If you change the column order, width or alignment, or if you hide a column on the Structure tab, these changes will also be applied to the List tab. Conversely, any changes made to the column properties on the List tab are also automatically applied to the Structure tab.
