To Create a Work Region
Create a simplified representation by creating a work region that removes a portion of the model from display. Each simplified representation can have its own work region.
1. Click View Manager on the Graphics toolbar, or click View > Manage Views > View Manager. The View Manager dialog box opens.
2. In the Simp Rep tab Names column, double-click to select the representation, or select the representation and click Options > Set Active.
3. Right-click and select Redefine. The EDIT METHOD menu appears.
4. Click Work Region. The SOLID OPTS menu appears.
5. Specify the type of cut you want to create by clicking one of the commands in the SOLID OPTS menu.
6. The dialog box for defining the cut of the specified type appears. Define the cut feature.
7. When you finish defining the cut, click OK from the dialog box.
* 
Work regions behave in a manner similar to cut features, except that geometry is removed from the display only rather than physically removed from the model (that is, from the regeneration list).
When a simplified representation is active, the system applies the work region cut; otherwise, the cut is suppressed.
Once you create a work region, you can redefine it by using the Redefine command in the WORK REGION menu; this brings up the dialog box so you can select the feature elements that you want to redefine.
To delete a work region, click Delete from the WORK REGION menu.
