About the Offset Geometry Feature
Use the Offset Geometry tool to offset selected geometry from solid geometry or from a quilt and attach it to the solid or quilt. When you select a quilt, the quilt geometry is offset from its original position. When you select a surface, the surface is offset and the surrounding surfaces are extended unless you specifically remove them from the selection.
The Offset Geometry tool acts on a single geometry selection. To offset another geometry selection you must create a new offset geometry feature.
