All objects will be placed on certain levels. The Level Manager directs the display of all levels
1) The icon for the level manager is in the tool box primary tools
2) We recommend adding the two additional columns of ‘Global Display’ and ‘Lock’ via right click on the header / Save Layout
3) The ‘Global Display’ option is for switching the display ON and OFF. And Lock means the objects on this level are visible but cannot be changed
We use this for the level PS_WORKFRAME, by standard
4) Instead of using the level manager for setting the ‘Global Display’, you can use the Level Display feature. Switching ON and OFF just by clicking on the names
