162 Working With Modules
4. Release the left mouse button. The block appears in the workspace.
Important: A new module from the tree's node can also be dragged
and dropped onto another tree's node within the Diagram
Explorer.
Encapsulating Blocks
Create a new module to simplify the structure of your diagram. Use the
encapsulate function to combine several blocks into a single module. You
can easily reverse this process by unencapsulating the module. Refer to
the Unencapsulating a Module section.
Important: Do not attempt to encapsulate a group of blocks that
could result in multiple inputs or outputs. This results in
lost connections.
To create one new module by encapsulating several blocks:
1. Select the blocks and connections that you want to encapsulate.
2. From the menu bar, select Module. The Module menu appears.
