Layer Keys and Layer Keying
When you create an object, the layer key that is associated with the object automatically places that object on the layer
to which it is mapped. Using layer keys to automatically place objects on predefined layers is called layer keying. Usually,
you key objects to layers that conform to a layer standard. Each layer standard names layers according to a set of rules
that you can modify. For more information, see “
Creating and Editing Layer Standards
” on page 434.
Layer Key Styles
You can create different sets of layer keys, called layer key styles, that you can use to place objects on defined layers in
your drawings. Each layer key style contains a set of layer keys. Both the AIA and BS1192 layer key styles contain layer
keys and layer properties, including layer name, description, color, linetype, lineweight, plot style, and plot settings
for all of the AEC objects. You can import the AIA and BS1192 layer standards and layer key styles that are provided
with AutoCAD Architecture 2008 from the AecLayerStd.dwg in the \Documents and Settings\All Users\Application
Data\Ar\ACD-A 2008\enu\Layers folder. You can modify these styles, if needed, or create new layer key styles. You can
also create layer key styles from LY files.
Properties of Layer Key Styles
You can add and remove layer keys from layer key styles. Default layer keys cannot be removed. The properties of any
layer in an existing layer key style can also be edited. You can change the layer name, description, color, linetype,
lineweight, plot style, and plot settings for the layer that each layer key maps to. If the layer key style is based on a
layer standard, you can use overrides on all or some of the layer keys within the layer key style. For more information
about overrides, see “
Layer Key Overrides
” on page 432.
NOTE The default Standard layer key style is not based on a layer standard. It contains the default set of layer keys.
LY Files and Layer Key Styles
If you have LY files from S8 or Release 1 of Architectural Desktop that you want to use, you can create a new layer key
style from an LY file. For more information see “
Creating a Layer Key Style from an LY File
” on page 430.
Overrides to Layer Key Styles
Whether you create an original layer key style or one from an existing LY file, if you want to use overrides, you must
base the layer key style on a layer standard in the current drawing. If you create a nonstandard layer key style, the
Overrides On/Off command is unavailable. If you copy a layer key style, you can use layer key overrides only if the
layer key style that you copied is based on a layer standard. For more information about using layer key overrides, see
“
Layer Key Overrides
” on page 432.
Managing Layer Key Styles
To create, edit, copy, or purge layer key styles, you access the Style Manager. The Style Manager provides a central
location in AutoCAD Architecture, where you can work with styles from multiple drawings and templates. For more
information about using the Style Manager, see “
Style Manager
” on page 489.
