ProModel uses the COMBINE statement to accumulate and consolidate a specified quantity of entities into a single entity, optionally with a different name. The entities may be the same type of entity or they may be different. Combined entities lose their identities and attributes and you cannot ungroup them later. When defining the location, the location capacity where you use the COMBINE statement should be at least as large as the combined quantity. The following shows the correct syntax for combining 5 Castings into a single entity called Pallet (the location, Out, should have a capacity of at least 5).
