In order to define an unconformity event place an Unconformity icon 
in the History window.
You will then be provided with the Unconformity definition window.
Unconformities are planar and are infinite in extent. The X,Y,Z coordinates define one point on the plane of the unconformities (or the top right hand corner of the bounding rectangle of a DXF surface, if defined), and the other parameters are normal structural definitions. A new stratigraphy above the unconformity will also have to be defined.
