Every number below is from the verification report. Where a difference is real, the report names it.
| Check | Result |
|---|---|
| A 200-member tower frame, second order | Reactions within 0.04 %. End forces within 0.16 %. Deflections within 0.44 %. After removing the other program's print rounding, the largest difference is 0.47 %. |
| Nine single-span beams | Moment within 0.22 %, shear within 0.08 %, deflection within 0.66 %. |
| A portal shed with haunches | Within 2 % on 8 of 11 quantities. Three values near 4 %, each explained in the report. |
| A middle frame, haunched method | Reactions within 0.06 %. Knee, apex and mid-rafter moments within 0.09 %. Sway within 0.29 %. |
| Steel member resistances | Within 1.74 %. Interaction formulas within 0.02 %. |
| Base plates (a set of worked examples with printed results) | Within 0.6 %, most at 0.00 %. |
| Wind: peak pressure | Within about 1.2 %. |
| Plastic collapse load factors | Textbook portal frames match exactly (1.6667 and 2.000). |
Where a difference is real, the verification report names it. Three analysis methods — elastic, haunched and plastic hinge — run side by side for a second opinion on every job.
Designed, drawn, quoted and re-issued after client comments in a day. In a test on a copy of that job, four skin moves each left the drawing checker with zero failures, and the cleats, girts and sheeting followed. Moving a frame carries its bases, cladding and openings with it.
Priced as five deck options, each as its own quote, from one frame model.
Laid out by an optimiser that respects forklift aisle widths, doors, columns and ceiling height. It was then designed, drawn and quoted.
A welding table's nine plate parts nested on a single 1 210 × 2 500 sheet at 76.8 % use, with 782 lead-ins and 36 cooling points, and an estimated cut time of 83 minutes.
Every part and all 447 assemblies matched, and every mark count equals the original report.
