You can organize dimensional and user-defined parameters into groups, and control whether they are displayed in the Parameters Manager list.
When many dimensional and user-defined parameters are defined in a drawing, it can be useful to use the Parameters Manager to create several parameter groups, and then assign the parameters to one or more of the groups with a simple drag and drop operation. The result lets you view one group of parameters at a time, organizing and limiting their display in the Parameters Manager. Thus, parameter groups are used as a display filter for the parameter list.
Expanding the filter tree in the Parameters Manager displays all group filters created in the current space, Model space or a layout. There are two predefined filters displayed in the filter tree that cannot be edited:
When you use the Invert Filter option, it will display all the parameters not in the group instead of displaying only the parameters belonging to the group.
You can enter characters and wildcards such as * in the edit box of the Parameters Manager to search for parameters by name. This immediately filters the parameter list as you enter the characters.
