■ Avoid using the "Edit Material" or "New Material" buttons on the "Materials" tab of your style editor. While these may seem like efficient ways of editing and creating new materials "on the fly", they can be dangerous, as they make it easy to accidentally edit a material that has been applied to a multitude of different object styles, having an unintended and potentially drastic effect on the graphic quality of your drawing, as well as creating a material that deviates from your standard material definitions. The "Edit Material" and "New Material" buttons available in the style editor.These may seem like efficient and handy ways of creating materials on the fly, but their use should be discouraged as they make it easy to accidentally create non-standard materials. ■ Assign commonly used standard materials to palette-based tools so that users can access them quickly and easily without having to browse for your material library file in Style Manager. ■ Material Definitions are essentially nothing more than a collection of display representations. Therefore, every material definition you create should have style overrides placed on every display representation. ■ When defining and editing materials, keep level of detail in mind, especially when you are defining hatch patterns and hatch pattern scale. In the default template drawings there are three display representations for material definitions that are meant to address scale dependency. You can, of course, create additional display configurations and associated display representations for additional scale dependency. The existing display representations for scale dependency are: Display Configuration Material Display Representation General HIgh Detail High Detail General Medium Detail Medium Detail General Low Detail Low Detail ■ When editing a material definition's "General Screened" or "General Reflected Screened" you should assign the components to a layer that has a color or plot style assigned to it that will plot screened with color and line type set to "BYLAYER". These display representations are meant for use with consultants who need a screened background drawing. You can set one of the screened display configurations current and export your AutoCAD Architecture drawing to an AutoCAD format. By assigning the components to screened layers you provide your consultants and collaborators the ability to control their display via traditional AutoCAD layer control. NOTE By default, the screened display representations in the Imperial and Metric templates for use in the United States assign material display components to the layer "A-Anno-Scrn" in accordance with the AIA layering guidelines. IMPORTANT If you want to use material definitions to control the display of object components in a 2D Section/Elevation object on the cut line you must first set the "Defining Line" component in the 2D Section/Elevation's "General" display representation to "By Material". Next, edit the material definitions being used in the section and set the "2D Section/Elevation Linework" component to the color, line type, line weight and plot style you would like to see in the Section/Elevation. You will also need to make sure the setting "Maintain layer, color, linetype properties form the Display Set used during generation" is toggled off. Multi-View Block Definitions Multi-View Block Definitions can be used for both geometric symbols and annotation symbols (primarily chases and column grid bubbles). 564 | Chapter 13 Content Creation Guidelines
