An AI built one parametric cricket bat per English willow grade in Siemens Solid Edge from the best dimensions of an earlier analysis. Solid Edge measured Grade 1 at 1.205 kg, within 0.25 % of the analysis, and the four grades range from 1.205 to 1.306 kg.

What was asked

SphereHarness chat showing the long request describing the Grade 1 bat shape and material values — The request in plain words: shape, material values, file name and what to measure.

The dimensions for a short-handle bat in English willow Grade 1 went to the SphereHarness chat in plain words: the sizes, the shape, and the willow's material values. The request includes "Keep the willow blade and the cane handle as two bodies" and ends "Save it as CricketBat_EW_Grade1.par in C:\CADDemo\cricket-bat-se. Show it in an isometric view fitted to the window, then tell me the measured volume, mass and overall size of the bat."

What the agent did

The agent drove Solid Edge itself: named variables, five cross-sections along the blade lofted into the spine, the bow and the toe, then a cane handle and the splice as a second body. The Grade 1 bat has a light willow blade and a darker cane handle saved as its own part.

Table comparing Grade 1 analysis values with Solid Edge measured values, volume 3,171,738.5 mm3 — Grade 1 measured in Solid Edge: 3,171,738.5 mm3 (-0.23 %) and 1.205 kg.

Grades 2, 3 and 4 followed, each with its own spine, thinner edges and a 6 mm bow for grades 3 and 4, each saved as its own part.

What we measured

For Grade 1, Solid Edge gave 851 mm overall, 108 mm wide, two bodies, a volume of 3,171,738.5 mm3 (-0.23 % against the analysis) and 1.205 kg at 380 kg/m3.

Table of four English willow grades with spine, edge, bow, toe, density, volume and mass — Four grades: 1.205, 1.250, 1.278 and 1.306 kg.

Across the grades the mass climbs from 1.205 kg to 1.306 kg even as the bats get slimmer: 1.250 kg for Grade 2 and 1.278 kg for Grade 3. The analysis values are 1.208, 1.252, 1.280 and 1.309 kg, and every volume is within 0.25 %.

The drawings

The A3 drawing after the title block was redrawn with the company name.

An A3 drawing of the Grade 1 bat has the face, the side profile with spine, bow and toe, a section at the middle and the handle end view, with 11 dimensions placed. The stock title block still read Solid Edge, so the person asked for a company name, and the agent redrew the title block with PLM CAD, then made the same sheet for grades 2, 3 and 4.

What did not work as a dimension

Table checking drawing dimensions for four grades, with match results and two note-only rows — The drawing check: five rows match, two are notes.

Every placed dimension matched its own bat. Spine depth and the middle position are still notes, because the drawing cannot dimension the curved edges of the loft yet; the video says this was filed as a product issue. The material values for stiffness and strength are kept as file properties, because Solid Edge took only the density.

Finally all four bats were placed side by side in one assembly, from Grade 1 on the left to Grade 4 on the right. The run used Claude Agent (Opus) in the SphereHarness desktop agent 1.3.8.
