Rebuild
Rebuilds the model with changes.
To rebuild the model:
Click Rebuild
(Standard toolbar) or Edit,
Rebuild, or press
Ctrl + B. Rebuilds only the features that changed since the last
rebuild.
To rebuild all features, press Ctrl
+ Q. Can take significantly more time, depending on the complexity
of your model.
When you reorder an imported
feature or any other feature with no parent or child, the part does not
rebuild - only the FeatureManager design tree rebuilds.
To control the rebuild action:
Click Options 
(Standard toolbar)
or Tools, Options.
Select
Stop, Continue,
or Prompt for When rebuild error occurs,
then click OK.
With Stop or Prompt,
the rebuild action stops for each error so you can fix feature failures
one at a time.
If you drag the rollback bar
to a specific position, the model is rebuilt to that position regardless
of errors.
The model is not rebuilt if:
The document
is not the top-level document.
The feature
with the error is directly above the rollbar.
The part
does not have any more rebuild errors during the current rebuild than
it did in the previous one.
