Adding supports allow you to assign precedence relationships (predecessor/successor) between elements.

There are 4 options to assign supports in ALICE:

• Automatic Support
• Edit Data Tabular format 

More instructions and use-case videos about Support as Chain and Automatic Support can be found in the Automatic Support and Support as Chain article.
