Working with Layers

Most drawings contain multiple layers of information. WLAN Management Software allows you to hide, add and delete
individual layers. You also can add and remove objects and move objects from one layer to another. For RF planning,
you can convert existing objects into RF obstacles and add new RF obstacles.
Generally, only some of a drawing's layers contain details relevant to RF planning. You can hide layers to simplify a
drawing. WLAN Management Software performs RF calculations only with information in visible layers. Each drawing
that you import into WLAN Management Software has a layer 0, which contains information that WLAN Management
Software creates. You can hide layer 0 but you cannot delete it, and WLAN Management Software requires layer 0 to be
visible when calculating RF coverage or performing rogue detection. If you start one of these operations with layer 0
hidden, WLAN Management Software displays a message offering to make layer 0 visible again.
For best performance and simpler planning, Nortel recommends that you hide or remove unnecessary layers and remove
unnecessary objects. The Clean Layout option automatically deletes all objects that meet the cleanup criteria, which you
can modify. (See "Cleaning Up a Drawing" (page 95).) You also can select and delete individual objects.
