How to offset

How to fit the brick to the dimensions while moving it forward?
I want to move forward along the curve.

make a perpframe frame from the same ‘t’ outputs, use the plane axis that’s equal to ‘forward’ to move your geometries - or post a .gh file

Sorry, I don’t understand. How do you move forward for each plane axis?

The bricks are staggered because their positions are not right.

actually not needed (the perp frame), just use Y axis of your horizontal planes:
