If your trying to count tiles etc then an array method works much better, as a Tile can be a rectang/pline shape.
You could do a 2 point pick of the exploded hatch to get the length and width then do an undo to make the hatch again. Then divide the total area by the tile area. Its the way they are sold in the box. Tiles per square metre. Note need to take into account tile gap.
@jaimuthu You cannot count the shapes in a HATCH pattern without exploding it then creating full tiles from the remnants. Or just creating an ARRAY of a full tile in that area then count the numbers. Or use a BLOCK for a full tile to count those. Or... I am sure there are other ways, how would you like to proceed?
