# Item Sets

Product (Items) are naturally grouped in Item Classes. However it is possible that you may want to group a set of items that are in
different classes when configuring check sheets that should only be enabled for a certain grouping of products.
Item Sets can also be used to group together items that share a common set of tolerance specifications and the ability to do this
really simplifies the management of tolerances rather than having to specify the same tolerances for every product you have.
