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.

„In AutoCAD:

Click-drag to select unwanted objects and delete them.

When all unwanted objects are deleted, purge the drawing of all unwanted layers, blocks, and fonts by selecting

File > Drawing Utilities > Purge. Make sure purge nested items is selected. Click Purge until the option is greyed out.

CAUTION: In AutoCAD, you cannot delete a layer if the layer is not empty. However, in TurboCAD, Options > Layers allows you to delete a layer even if there are objects in it.

„Create RF-specific layers and move walls, windows, doors, and other objects that affect RF propagation from other layers into the new layers. For example, create a new layer called RF-ExtWallsfor external walls, and move all external wall objects into that layer. In 3WXM, you can easily select all objects in the layer and assign the same RF attenuation value to them. Create RF-IntWallsfor interior walls and RF-Windowsfor windows.

If walls or windows are shown with multiple parallel lines, delete all but one of the lines. (3WXM can remove unneeded parallel lines during cleanup too, depending on how close together the lines are.)

To create a new layer in TurboCAD 9, select Options > Layers. In AutoCAD, select Format > Layer.
