Object mode - How do I turn off visible wireframe? Simple question.  I do not know but maybe I pressed a button or an option but I can still see the object wireframe in object mode.

How can I disable it to be in normal object mode as in the green part of the helmet I am working on.
The answer is simple as you said. Select your object, go to the object properties panel and the make sure that wireframe isn't enabled under viewport display.
