When designs contain large numbers of layers, it can be difficult to select only the layers you're interested in, such as connectivity or
metal layers. Calibre DESIGNrev allows you to quickly select these layers using the layer search (at the top of the layer panel). In this
video you'll learn how to select layers and to dim or hide unselected layers for better visualization in the design. You'll also learn how to
create layer filters with user defined layers, allowing you to toggle between different layer views.
