You can change
an object's plot style only if the drawing uses named plot style
tables. If the drawing uses color-dependent plot style tables,
change the object's color to alter its plotted appearance.
Select one or more objects whose plot style you want to
change.
Right-click in the drawing area. Click Properties.
In the Properties palette, select a plot style from the list of
available plot styles. Click the column next to Plot Style.
The plot styles
listed are those already in use by objects and in the plot style
table attached to the current layout.
To select a plot style from a different plot style table,
select Other. In the Select Plot Style dialog box, you can attach a
different plot style table to the current layout and select a plot
style from that plot style table.
To edit the current plot style table, click Editor.
Click OK when finished.
Any changes
made in the Properties palette are immediate. If you change the
plot style table attached to the current layout, both model space
and paper space objects are affected.
