The prompt

2D CAD drawing of a hollow interlocking concrete block profile. Top view. Units: mm. Outer rectangle: 400mm wide by 200mm deep. Wall thickness 25mm. Inside the outer rectangle, draw two smaller rectangular cutouts for the hollow cores. Each cutout is 150mm wide by 150mm deep. Space them evenly so there is 25mm of wall between the two cutouts and 25mm of wall on each side. On the top edge, add 4 evenly spaced rectangular protrusions. On the bottom edge, add 3 evenly spaced rectangular protrusions, offset in the gaps between the top protrusions. Each protrusion is 40mm wide and 20mm tall. All corners 90 degrees. Black outline, no fill. SVG format. Export as SVG.
