The Objects visible and Objects invisible commands have the same functions as the eye symbol to the right of the object name. The only difference lies in the fact that these commands allow you to render a whole selection visible or invisible. The Objects visible command makes all selected objects visible. When working in 3D mode, visible objects are converted into the 2D window. Selecting the Objects invisible command hides the selected objects. Hidden objects in imported, pasted or placed drawings are not converted into the 2D window.
