In some instances, a translated region may require editing. Reasons include the following: 
- A surface is translated with trim going the wrong way. 
- A loop meant for the outer edge is used as the inner edge. 
- The natural border of the surface is used as the outer edge. 
- The surface contains a hole that must be removed. 
- The region includes a self-intersecting loop. 
Inner and outer regions can be repaired on faces. Only inner regions can be repaired on a quilt. 
- Open a file that contains surface geometry and enter the repair or construction environment. 
- On the ribbon, do one of the following: - Click Repair tab  Modify panel Modify panel Edit Regions. Edit Regions.
- Click Construction tab  Surface panel Surface panel Edit Regions. Edit Regions.
 .
- In the graphics window, click a face to repair. The selected face is highlighted. 
- Click regions in the face to keep. Filled holes are not planar but follow the contours of the underlying surface. 
- Click Done. The selected regions are retained while unselected regions and unneeded loops are removed.
