Active Line Style
Sets the Active Line Style and changes the line styles of selected elements to the line style that is chosen.
The Active Line Style specifies the line style of an element upon placement, and if set to a standard line style, is stored as a value in the 0-7 range.
If elements are selected, their line styles will change to the newly selected line style.
If one or more elements are selected, the line style of each is changed to the chosen line style.
Line_style can be a standard line style number (0-7) or the name of a custom line style.
Line Style can also be set ByCell or ByLevel. If ByCell is selected, when a cell is placed the active line style is used in place of the line style used when the cell was created. If ByLevel is selected, when an element is placed the line style defined for the active level is used to display the element.
