Dear Thiago,

Yes.
The setting that I have told you applies for new Models/Diagrams that you create after changing this setting.

If you want to make the Attribute/Operation compartment of new models invisible in the existing diagrams,
1. Go to the Property View of the Diagram.
2. Open [Initial Visibility] Tab and check off [Attribute/Operation Compartment Visibility]
























After checking them off, models you create will not show the Attribute/Operations.

Best regrads,
Satomi
