As of PitStop 2018, you can quickly combine multiple selected shapes into one shape and vice versa (divide shapes into multiple parts). To that end, an extra option (Combine/Divide Shapes) was added to the PitStop Pro Object menu, to the context menu and in the Enfocus Inspector.
When using the Object menu and the context menu, the selected shapes are modified; the originals are not kept.
If you don't want this, you can first duplicate the selection and work on this copy, or you can combine and divide the objects using the Enfocus Inspector, which has a Keep original objects checkbox (selected by default).
Note that there is one more way to do the same: the new "Combine and divide shapes" Action. For more information, refer to the Action List manual on our website.
