 Check for grouped objects, especially groups that span multiple layers
or include the entire drawing. If a grouped object contains objects
that you will to assign differing RF values to, or if some objects will not
become RF obstacles, ungroup the objects and delete the unneeded
objects. If all the RF objects in the grouped object will have the dame
RF value, you might want to leave the object grouped.
A grouped object can contain multiple layers, and can contain visible
and invisible objects. (When you select an object that spans multiple
layers, the object is not selected normally when you click on it.
Instead, a selection square appears, offset to the side of the object.) If
you decide to delete a grouped object, ensure that the object does
not contain objects to which you will need to assign RF values.
 Turn visible, unlock, and unfreeze all layers. Then delete unnecessary
layers. (Locking a layer keeps the layer visible but also prevents
changes to the layer. Freezing a layer locks the layer and makes it
invisible.)
In many cases, the information in invisible or frozen layers is not
related to objects that will be RF obstacles, and so is unnecessary in
the floor plan. The information you need to keep is the structural
information to which you will assign RF values in 3WXM.
To check the contents of the invisible layers to make sure the
information can be discarded, reverse the frozen/unfrozen status of all
layers, to that only the layers that normally are frozen are visible. In
TurboCAD, delete the unneeded layers. In AutoCAD, click-drag
around all the visible objects to select them, and delete the objects.
CAUTION: Do not use Ctrl+A (Select All) in AutoCAD to select the
objects to delete. This option selects all objects in the model space,
regardless of layer status (invisible, locked, or frozen). All invisible objects
are unprotected and will be deleted. Instead, always use click-drag to
select multiple objects, or lock the layers you want to keep first.
 Remove all blocks, line types, and layers that are unused.
 In TurboCAD:
To delete a block, select it on the Blocks palette and click Delete.
A line type is an object. To delete an object, select the object and
select Edit > Clear > Selection.
