The prompt

Sure. For TextoCAD, keep it simple: Create a 2D reinforced-concrete septic tank, 2.4 m long × 1.2 m wide × 1.4 m deep, with 1.2 m liquid depth and 0.2 m freeboard. Use two compartments, 2/3 and 1/3. Include 100 mm inlet/outlet pipes, concrete baffles, two 500 mm manholes, scum and sludge zones. Use 150 mm concrete walls, base and top slab, with Ø10 mm rebar @ 200 mm each way. Show plan, section, dimensions, reinforcement, inlet/outlet, baffles, and manholes.
