Surface reverse is an exact operation. Follow these steps to reverse a surface:
You must have an existing surface to use Surface reverse.
Use the Surface wizard or select Surface reverse from the surface toolbar flyout.
Set whether to create new surface or modify an existing surface.
Name the surface for future reference if it’s a new surface.
Click Pick and select the source surface, or select the surface from the dropdown list box.
Select whether you want to:
reverse normals
transpose row/column
reverse trim loops
Click Finish or OK to create the new surface or edit the existing surface, whichever matches your settings.
Sheets can also be reversed using the Surface Reverse operator. They cannot be selected with the mouse, but instead should be picked from the drop down list box in step 5 above.
