Chapter 4 Creating and editing models
100
Enabling and disabling automatic part creation
Part creation in the Model Editor is optional. By default,
automatic part creation is enabled. However, if you
previously disabled part creation, you will need to enable
it before creating a new model and part.
To automatically create parts for new models
1 From the Tools menu, choose Options.
2 If not already checked, select Always Create Part to
enable automatic part creation.
3 Under Save Part To, enter the name of the part library
for the new part. Choose either:
• Part Library Path Same As Model Library to create
or open the *.OLB file that has the same name
prefix as the currently open model library (*.LIB).
• User-Defined Part Library, and then enter a file
name in the Part Library Name text box.
Note
If you select a user-defined Part library, the Model Editor saves all
new parts to the specified file until you change it.
Saving global models (and parts)
When you save your changes, the Model Editor does the
following for you:
• Saves the model definition to the model library that
you originally opened.
•
If you had the automatic part creation option enabled,
saves the part definition to
MODEL_LIBRARY_NAME.OLB.
To save the new model (and part)
1 From the File menu, choose Save to update
MODEL_LIBRARY_NAME.LIB (and, if you enabled
part creation, MODEL_LIBRARY_NAME.OLB), and
save them to disk.
