The Line/Fill tab of the Format Multiple Objects dialog is used to customize the line size/color and the fill color of selected objects. You can view this tab by selecting 
from the Formatting ribbon group on the Draw ribbon tab after object(s) have been selected on the oneline. This tab’s controls can be used to change the appearance of most, but not all, screen objects. Only options that are relevant for the types of objects selected will be enabled. The Line/Fill tab has the following fields/commands:
Line Thickness
Thickness of the line in pixels. Line can mean either an actual transmission line or background line object, the lines used to draw objects like loads and switched shunts, or the border line that surrounds objects like generators and buses.
Dashed
Allows setting a line to appear as a dashed line on the diagram. There are three types of line dashing to choose from in the drop down menu for this option.
This field shows the current line color. To change the line’s color, click on the box displaying the current line color, or click the Change button next to the Line Color box. This displays the Color dialog. Select the desired color and select OK to change the color, or click Cancel if you do not wish to change the color.
Line Color 2
The Line Color 2 field applies only to transformer and generator objects. Check the Use Color 2 field to implement use of the color and specify the color through the color box. The color can be changed in the same manner as described above for Line Color.
Transformers can be represented by different colors on each side of the transformer coils. This is commonly used to color match each side of the transformer with the color used to represent the voltage level of the transmission system on each particular side of the transformer. However, you can customize the colors for selected transformers by modifying them here. The Line Color 2 field ALWAYS applies to the high voltage side of the transformer.
The rotor image selected for generator objects can be filled with Line Color 2.
Click on this box to toggle whether or not to fill the background for the selected objects with the selected background fill color. Text objects such as Text, Bus Fields, Generator Fields, Load Fields, Switched Shunt Fields, Line Fields, Transformer Fields, Area Fields, background objects such as Background Lines and Background Rectangles, Background Triangles and generator objects can be filled.
This field shows the current fill color. To change the fill color, click on the box that displays the current fill color, or click the Change button next to this box. This displays the Color dialog. Click on the desired color and the select OK to change the color, or click Cancel if you do not wish to change the color.
