Project can contain many Setups. They are shown under the Setups branch in the explorer.
A Setup is an entity that contains an ordered list of toolpaths. They are especially useful for projects that contain a large number of toolpaths as they help you to organise your toolpaths, provide a structured workflow, and ensure that the order of toolpaths in an NC Program is not broken.
Additionally you can apply fixture offsets to Setups, which enables you to easily offset all of the toolpath moves contained in a setup to new locations.
