Must Not Have Gaps :Create Feature Must Be Covered By : Create Feature Requires that polygons of one feature class must be contained within polygons of another feature class. Must Not Overlap With: Subtract, Merge Requires that the interior of polygons in one feature class must not overlap with the interior of polygons in another feature class. Must Be Covered By Feature Class Of :Subtract, Create Feature Requires that a polygon in one feature class must share all of its area with polygons in another feature class. Must Cover Each Other : Subtract, Create Feature Requires that the polygons of one feature class must share all of their area with the polygons of another feature class. Boundary Must Be Covered By : Create Feature Requires that boundaries of polygon features must be covered by lines in another feature class. Area Boundary Must Be Covered By Boundary Of :None Requires that boundaries of polygon features in one feature class be covered by boundaries of polygon features in another feature class. Contains Point : Create Feature Requires that a polygon in one feature class contain at least one point from another feature class. Points must be within the polygon, not on the boundary. Line rules Must Be Larger Than Cluster Tolerance : Delete Must Not Overlap :Subtract Requires that lines not overlap with lines in the same feature class. Must Not Intersect : Split, Subtract Requires that line features from the same feature class not cross or overlap each other. Must Not Have Dangles :Extend, Trim, Snap Requires that a line feature must touch lines from the same feature class at both endpoints. Must Not Have Pseudonodes : Merge to Largest, Merge Requires that a line connect to at least two other lines at each endpoint. Must Not Intersect Or Touch Interior :Subtract, Split Requires that a line in one feature class must only touch other lines of the same feature class at endpoints. Must Not Overlap With : Subtract Requires that a line from
