To Update a Drawing of Model Geometry
To update a drawing after making changes to its source model, regenerate the view. Regenerating a drawing view is not object-action oriented; you must choose the command first, and then select the view.
Do one of the following:
In Drawing mode, click Review > Update Drawing View.
Select one or more drawing views.
Set the configuration file option auto_regen_views to yes.
