To activate the symbology settings, check the Level Symbology box in the View Attributes dialog box. You can get to the View Attributes dialog box by selecting the option from the Settings menu (Settings>View Attributes) or by clicking on the logo on any view window. To make plots using those settings, select Print Attributes on the Settings menu of the Plot dialog box. Then check the Level Symbology box.
Open Level Manager.
Toggle the Symbology setting to Overrides as shown at the right.
If the Color, Style and Weight columns do not accurately depict the levels (perhaps the Color column is gray and/or the Style/Weight columns are defaulted to 0), click on Level Update. This should take care of the problem.
If nothing changes, detach the existing Level Library - File>Library>Detach. If a box pops up, detach the library by selecting OK. If no box pops up then no library was attached. Import the Level Library - Levels>Import.
Choose the corresponding Level Library (.csv file). For example: 12345ali.dgn's .csv file is ali.csv. Click on the Update Levels button. The levels should now appear correct - Color, Style and Weight in Level Manager. This will have to be done to each file in the Reference File list by using the Tools>Exchange from the References or by going into each file separately. Please note, if exf.csv doesn't exist, attach exd.csv and then attach txt.csv also.
Highlight the level(s) needing to use symbology.
Click on the attribute to change the symbology.
Click on a highlighted "color box". A Symbology Color table pops up. Choose a color and click OK. Choosing the Override Off button will disable the override settings for the chosen level(s).
Click on a highlighted Style (Linestyle). A Symbology Style box pops up. Choose a linestyle and click OK. Choosing the Override Off button will disable the override settings for the chosen level(s).
Click on a highlighted Weight. A Symbology Weight box pops up. Choose a weight and click OK. Choosing the Override Off button will disable the override settings for the chosen level(s).
Note that if you Update Levels at the "Master Level" you will loose all of the symbology work you have worked so hard to achieve. Once you
Update Levels, the level defaults will be in place.
