You can share equations and global variables among models.
You can export all equations or selected equations to a text file, and
import all equations or selected equations from a text file. The text file can be shared
with other parts and assemblies that use the same global variables and equations.
You can create permanent links with text files
using the Link to external file, so that changes to the text file
are propagated to the model.
The Link to external file
always creates a link with the external file. The Export and
Import processes include options for one-time exports and
imports without a link.
