doneThe table is now 2400 mm long and has a third bench beam halfway along, under both benches, matching the other two. I checked the size (2400 × 1450 × 750 mm) and the drawing. The table now has 16 parts, still under your limit of 20.
- **More length, not more boards:** the top and bench boards are longer, but there are still five top boards and two benches.
- **Same legs:** the legs are still 200 mm in from each end, so they now stand about 2000 mm apart, centre to centre.
- **Middle beam:** the new beam stays halfway along when you change the length or leg position in the Inputs panel. It has no leg under it, so it braces the two benches but doesn't carry weight to the ground.
All the inputs from before are still in the Inputs panel. If you'd like the middle beam to have its own support, I can add a centre leg pair, or a brace up to the top.

promptMake the table 2400 mm long, and give it a third bench beam.
doneI built your picnic table from 15 parts:
- **Top:** five boards, each 140 mm wide with 10 mm gaps between them. The top is 1800 × 740 mm and stands 750 mm high.
- **Benches:** two boards, each 250 mm wide with the seat at 450 mm. They run along both long sides, 600 mm out from the centre line.
- **Legs:** four square legs, 70 mm thick, set 200 mm in from each end.
- **Supports:** at each end, a crosspiece under the top and a longer bench crossbeam reaching out to carry both benches. Both are fixed against the outer face of the legs.
Overall it measures 1800 × 1450 × 750 mm. I checked the size and looked at the drawing. The boards are saddle brown, the benches sienna, the legs olive green and the cross members slate grey.
In the Inputs panel you can change these, most with sliders: table length, board width, gap and thickness, table height, bench height, width and distance from the centre line, leg size, and how far in the legs sit from the ends. The ranges are a guess at sensible sizes, and I didn't test every extreme.
**Limits:**
- The legs are straight and vertical, not the angled A-frame legs many picnic tables have.
- The parts are simple blocks that touch or overlap; there are no joints, bolts or cut-outs.
- The bench beams are a fixed length worked out from the bench width and position. If you move the legs far in, the beams still reach the benches, but they only touch the legs at one face.

promptA simple picnic table: a top of five boards and two benches, all on four legs. Keep it under 20 parts.
