Before a faulted map can be gridded, fault blocks must be assigned to all of the areas defined by the fault lines and map boundaries. To assign the fault blocks either select Edit > Faults > Assign Fault Block, Popup > Faults > Assign Fault Block or click on the Faults button on the toolbar and select Assign Fault Block. Marquee boxes will then be draw at all of the points on the fault lines and the corners of the map. The fault block is formed similar to a polygon by clicking in a circle on all of the points or map boundaries that form the edges of the fault block. When the last point is reached double-click the mouse button. The Fault Blocks form will be displayed and can be edited as described in the section below.
