Then select your filler part and mark it as 'filler' and press apply, then preview the results. First select the part you want to nest, enter the number of copies required and press apply. You can also combine filler parts with other nested items, for example if you want to nest 20 of one part and then fill the remaining space with a filler part you can do just that. Simply mark the part as “filler” using the check box in the form and the software will identify the filler part with a green star in the 2D view, hit preview and see the results. We’ve introduced a new option in the nesting form that allows you to fill your sheet with a given part, this is useful for scenarios where you want to fill your sheet with parts but don’t know exactly how many will fit and so the software calculates that for you.
