Grouping and Merging sets

What is the difference between Grouping and Merging?

Grouping: 

Use this feature for a set with many subparts, like different rooms or areas. 

INT. BILL'S HOUSE - LIVING ROOM
INT. BILL'S HOUSE - STUDY
INT. BILL'S HOUSE - KITCHEN

These can all be grouped by the main set name "BILL'S HOUSE' and taking the rooms and making them 'subsets'. 

Grouping allows you to:

• Use one set number for all of the sets. 
• keep all the sets together on the work notes. 

Merging:

Use this feature when a set is the same place with different names. 

EXT. THE DRAKE MANSION

EXT MANSION

EXT THE DRAKE ESTATE

Every set has a 'Display name' and an 'Import name'.
