â– Layer Standards: Defined in the Layer Manager, layer standards are stored
in the same library drawing as the layer key style with which they are
associated. When the layer key style is imported into a drawing, the layer
standard on which it is based will import also.
â– Display Configurations: Default display configurations are stored in the
drawing template.
TIP Most content types have associated naming conventions that are documented
in this guide. As a global convention, it is acceptable to prefix any name with a
company or organization name to differentiate your custom content from the
default content supplied with AutoCAD Architecture.
National CAD Standard Compliance
The National CAD Standard version 3.1 is a consensus standard compiled
from three existing standards and guidelines by NIBS (The National Institute
of Building Sciences). These consist of the AIA Layer Guidelines version 3.0,
the CSI Uniform Drawing System (UDS) and the Tri-Services Plotting
Guidelines. The National CAD Standard v. 3.1 is supported where possible in
AutoCAD Architecture through the use of pre-configured Layer Standards,
Layer Key Styles, plot style tables and annotation tools. While it is not required
that custom content be compliant, when creating new content for use in the
United States you should take this support into account.
The Imperial templates provided with AutoCAD Architecture are pre-configured
to load the AIA Version 3 Layer Key Style by default. This is based on the AIA
Version 3 Layer Standard, which is in turn compliant with the AIA Layer
Guidelines version 3.0.
The AIA v3 Layer Key Style includes line weights and linetypes that are in
accordance with the Uniform Drawing System, and the colors that it specifies
are compliant with the Tri-Services plotting guidelines. Additionally, the
drawing default display representations for all objects in the template files
have been configured to adhere to the Tri-Services Guidelines and Uniform
Drawing System recommendations by assigning appropriate colors, linetypes,
line weights and plot styles to all display components.
