Working with Layers

Most drawings contain multiple layers of information. 3WXM 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. 3WXM performs RF
calculations only with information in visible layers. Each drawing that you
import into 3WXM has a layer 0, which contains information that 3WXM
creates. You can hide layer 0 but you cannot delete it, and 3WXM
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,
3WXM displays a message offering to make layer 0 visible again.
