The Offset tab is used to create, select and delete surfaces offset from the basic surface (named OUTER).
Create an offset surface
-
Ensure that OUTER is the currently selected surface, as this is the only surface that can be offset.
-
Enter a name and the offset distance (positive inboard and negative outboard) in the relative input fields (Name and Distance.)
-
Select Offset.
To select or delete a surface
-
Select the surface from the list.
-
Select the relevant button, Select or Delete respectively.
Important: Surfaces containing PACE planar patches cannot be offset. If a surface is to be offset, then uncheck the Use plane patches checkbox on the General page of the Build Surface dialog in PACE before building the surface.
