The object symbol on the Map may be visible or hidden. An object can be hidden in one of the following ways:

1. At the system configuration stage. Visible objects are always reflected on the Map, whereas hidden objects are reflected only in "view hidden objects" mode. To switch-on "view hidden objects", use the Show hidden command of the Map functional menu called with a right mouse click on any place on the Map, which is free from object symbols.
   
   The status of the mode is indicated by a checkmark near the Show hidden objects button, which indicates that hidden objects can be viewed.
   

   Hidden objects view and hide function applies across all Map levels.

   
   

2. With the filter on the map layer. This filter applies only to the current layer and hides all objects of the specified type. Hiding and displaying objects is performed using the Hide (Filter) command in the Map functional menu called with a right mouse click on any place on the Map, which is free from object symbols.
