RVOs Manager Show/Hide command
Use this command to toggle the visibility of selected RVO, hiding RVO if it is visible, and showing it when it is hidden. The column Hidden of RVOs Manager grids displays the value True and False depending of the visibility of the RVO.
This command has the same effect that clicking on the Hide Command if the RVO is hidden in 3D Visualization View.
This command is disabled if no RVO is selected in grid.
