1. Click View in the main menu.
2. Click Act V-Set (under View Set).
The View Sets table appears.
3. Specify the new active view set in one of the following ways:
Select it from the View Sets table and click Apply (or double click the entry).
Enter the name of the view set in the user input line within double quotes (" ").
Select the view set from the Structure Browser.
4. Click OK.
这是帮助里的办法,但我这里根本没有第四步可以做,选完VIEW SET以后命令就完成了,就好像没有做这个操作一样结束了.
