I´d like to have a different pattern to represent the size of 1 brick of 25 cm
The bricks I use is like a LEGO block.
They must match the holes with 1 block of 1/2 block.
And I also must place the concrete columns based on each side of a door and window, and each 7 holes I must fill with concrete, and each place where I have 2 or more walls hit each other.

So if I have it visualy would be very nice.
