# Visual review
Outline: four through holes, circular blind pocket below central hole, horizontal step intersecting small upper middle hole. Outer hexagon has rounded upper right corner. There is no global feature symmetry; preserve individual feature rings.
d1 drawing: right hole fans too far across region, its top band is pinched; blind pocket needs a core, and large central boxes give shallow diagonals. Top outer round has a redundant boundary corner. Revise to local right-hole enclosure, compact central box widths and explicit pocket core. Step-hole transition is coherent and remains fixed.
d2: compact right hole ring now isolates feature, but background transitions contain one concave corner above its box and narrow diagonal below its left side. Adjust outer-boundary cut height and nearby interior junctions, without added blocks. Central and blind-pocket rings look appropriately scaled; top-round junction moves inward to provide a clear radial transition.
d3 pre-submission: all four through holes enclosed; lower pocket has concentric interior core. Step-hole cap is isolated with shared level-boundary corners. Right-hole enclosure is compact; remaining narrow transition immediately upper-left of that enclosure is local, not carried across the part. Outer upper-right round now has an inward cut. Background has broad left blocks and several top columns; no missing features. Submit this first 2-D passing layout to obtain actual quality/refinement diagnostics.
rev1 final drawing read after full run: same coherent feature coverage as d3; four holes remain empty, circular blind-pocket interior is meshed, and both sides of height-step share the intersecting-hole corners. No accidental change from numerical repairs. Remaining tradeoffs: several upper vertical strips and a locally narrow upper-left transition at the right-hole enclosure, plus broad diagonal background transitions on the right. Frozen realized SJ is 0.353892 at both densities, with no refinement degradation, all sharp edges captured and no inverted elements. Stop on first counted pass as instructed.
