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 layers contain details relevant to RF planning.
3WXM allows you to 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.
