If you work with resources in vPlan, your calendar view will look like this, for example:
Per day you can easily see which resources you have at your disposal. You can click them open to see the hours per resource in detail, whether these are machines, rooms or employees.
Have your resources disappeared from this view? If so, you can probably restore them by pressing the R key on your keyboard. This is a shortcut key in vPlan to easily show or hide resources. (See also: Shortcut keys)
You can show or hide multiple elements in vPlan with hotkeys. For instance, you can show/hide your capacity bar per day with the shortcut C.
You can also use the Eye at the top right of the screen; to manually show or hide information.
