Facility Drafting utilizes Level Symbology Overrides to keep track of levels in the CAD design file. The seed file has been set up to include a level symbology override definition for each level. The override is set to display COLOR only. The line weight and line style is not activated.
Level Symbology Override causes the elements on each level to appear as a specific color. When the user places the elements, they should be placed with color set to white (CO=0). However, with the level symbology overrride display turned on, the elements will appear to have color.
Each level has a color assigned to it. Because it is difficult to differentiate between more than 30 colors, the same color may be re-used many times for different levels in a design file. By utilizing the level symbology override display, it is easier to tell when an element is placed on the wrong level because it will appear with a different color.
Level Symbology Override uses the color table in the display of color for each level. In order to see the correct colors on each level, the color table provided by the District must be attached to the file.
Level Symbology for Reference Files
In order to more easily see reference files, you may change the reference file override color to be one single color for each attached reference file. Make this change in the file where the reference file is attached. Using Level Manager, display the levels for one reference file. Highlight all of that reference file's level, and change the color override. All levels will change simultaneously. Save settings to save the changes. When the reference file display is set to a single color, it is immediately apparent to the user which elements are in the active file, and which are in the reference file.
Changing The Level Symbology Table
Occasionally, it is necessary to modify the default level symbology settings.
A user may want to modify the default level symbology table because two levels, with the same color, are used extensively in a drawing. When this occurs it is difficult to tell which level is the active level. By changing the color display for one of the levels, it is easier to work on the correct levels.
The user may modify the level symbology table for any design file, if the result will make the file easier and clearer to work in. Changes to the level symbology table should only be required in special situations. Every effort should be made to keep level symbology table changes to a minimum.
