Use this procedure to edit linework in a 2D elevation. You can also edit individual lines in a 2D elevation by assigning them to display components in the elevation.
You can assign selected linework to fixed display components that determine the display of every elevation that you generate, or you can assign linework to display components that you have defined. After you assign linework to display components, you can change the display properties (visibility, color, layer, lineweight, linetype, and linetype scale) to change the display of lines.
A list of available display components is displayed.
For example, if you want to make the lines invisible, select Erased Vectors for Linework Component.
You can also click (Match existing linework), and select linework in the elevation whose display component you want to match.
