Note: Click the Default.edb button. This means that the definitions and
preferences will be initialized (get their initial values) from the Default.edb file that is
in the same directory as your ETABS.exe file. If the Default.edb file does not exist in
this directory then the definitions and preferences are initialized using ETABS built-in
defaults.
You should create your Default.edb file such that you most commonly click this
button.
In some cases you may want to click the Choose.edb button and specify a different
file from which the definitions and preferences are to be initialized. For example, a
certain client or project may require certain things in your model to be done in a
certain way that is different from your typical office standards. You could have a
specific .edb file set up for this client or project which could then be used to initialize
all models for the client or project. This will allow setting of the repeatedly used
preferences.
