Often times, especially when modeling Piping Systems, model objects are stacked and fastened to a wall - similar to this elevation example...

What obviously happens in a schematic or other Plan View is an unclear depiction of what is occurring.
Schematic Plan:

Hidden Line Plan:

When showing piping in schematic plan view under this type of condition, a standard practice is to show such beside each other for clarity,
but are then forced to compromise model accuracy to accommodate such...

Having the ability to use the "Displace Elements" tool in a Plan View would allow clarity, like that above, while maintaining model accuracy elsewhere, like that below.

Other disciplines may benefit from such functionality as well.
