There have been user edits to a 2D section or elevation that could not be reapplied to the 2D section or elevation.
When a 2D section or elevation cannot be updated, an error message is displayed in the status window.
To fix the problem, you can set the drawing to read/write instead of read-only, you can unlock the section layer, or
you can undo a specific user edit to a 2D section or elevation.
2D Elevation Styles
A 2D section/elevation style is a group of properties assigned to a 2D elevation that determines the appearance and
other characteristics of that object.
Using 2D Elevation Styles
A 2D section/elevation style controls the linework in an elevation, using design rules that determine how different
parts of the elevation are displayed. You can apply the style to one or more elevations to control their appearance. You
can also change the display of individual lines in the elevation, and save the changes in a 2D section/elevation style.
Display Components and Design Rules
Display components determine the graphical characteristics, such as color and linetype, of linework assigned to each
display component. Design rules determine how the linework in an elevation is assigned to display components.
When you create a design rule, you specify the part of the 2D elevation to control based on the color of those objects
in the building model and their context in the elevation. You then select the display component to use for linework
that meets the criteria you specified. You can assign the linework to a default display component or to a custom display
component that you have added to the style. For example, you might define a rule that assigns all objects that are color
150 in the model and located along the elevation line to a custom display component named Darker that you created
in the style. Or you might hide a staircase behind a wall using a rule that assigns all blue linework to the Hidden display
component.
Managing 2D Elevation Styles
To create, edit, copy, or purge styles, you access the Style Manager. The Style Manager provides a central location in
AutoCAD Architecture to work with styles from multiple drawings and templates. For more information about using
the Style Manager, see “
Style Manager ” on page 490.
Materials and 2D Elevation Styles
Two-dimensional elevation styles offer an easy way to assign materials to 2D elevation objects. You can specify which
section components should have its display controlled by materials and which do not. Custom components cannot
have any material assignments.
Subdivisions in 2D Elevation Styles and Materials
When you are creating subdivisions in your style, you usually want the objects in them to be visually distinct from
other subdivisions. When you have assigned materials to the objects, you can set the 2D elevation style so that it uses
the hatch pattern from the material, but the color and linetype from the subdivision display properties.
