What is a lens?

Lenses

A lens is a custom view of Connexions content. You can think of it as a fancy kind of list that will let you see Connexions through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to Connexions materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual Connexions member, a community, or a respected organization.

Creating a SubVI from Sections of a VI

Module by: National Instruments

You can simplify the block diagram of a VI by converting sections of the block diagram into subVIs. Convert a section of a VI into a subVI by using the Positioning tool to select the section of the block diagram you want to reuse and selecting Edit>>Create SubVI. An icon for the new subVI replaces the selected section of the block diagram. LabVIEW creates controls and indicators for the new subVI and wires the subVI to the existing wires. Figure 1 shows how to convert a selection into a subVI.
Figure 1
The new subVI uses a default pattern for the connector pane and a default icon. Double-click the subVI to edit the connector pane and icon, and to save the subVI.
Note: Do not select more than 28 objects to create a subVI because 28 is the maximum number of connections on a connector pane.
