v0.3.0 — deck plates, foot plates, OshCut catalog

Deck plates, caster/foot plates, and the OshCut catalog

Deck plates — plates:

Add a laser-cut sheet that rests on top of a layer (the base frame, the top frame, or any named blocking level):

plates:
  - layer: base
    material: {alloy: "304", thickness: 0.075in}
    post_clearance: 1mm

The plate is auto-notched around every vertical member that passes through it — corner notches at the posts, edge notches at perimeter supports, rounded interior holes for anything mid-plate — with the concave relief radius matched to the tube's outside corner radius. It shares rivet holes with the top faces of the rails, cross members, and spanners beneath it, and a hole that falls inside a notch is dropped on both the tube and the sheet so they never disagree. Plates ship as DXFs, join panel consolidation (two plates merge only when their cutout patterns coincide exactly under a flip), count toward the shipping estimate, and render brass-colored in the assembly STEP.

Caster & leveling-foot plates — feet:

Square plates welded to the underside of the bottom frame, flush with the exterior:

feet:
  material: {alloy: "A36", thickness: 0.25in}
  size: 4in
  pattern: {type: square, spacing: 3in, hole: 0.41in}   # + a centered stem hole by default
  mid: {count: 1, axis: width}                          # extra pairs for long spans

Four corners by default, with optional evenly spaced mid-span pairs for long units. The square bolt pattern now includes a centered stem/leveling-foot hole by default (center_hole, set to 0 to omit) so one plate accepts either a bolt-on or a threaded-stem caster; type: single cuts just the stem hole. The plates are welded gussets — no holes are cut into the tubes — and all identical, so they consolidate into a single foot part. The caster itself is not modeled.

OshCut catalog

vendor: oshcut is no longer a stub: all 93 published square-tube profiles (A513, A500, 304 ornamental, 6061 T6, 6063 T52) are encoded with true corner radii — extruded aluminum is a genuine sharp corner (r=0) — and the 235in max part length. Reference profile DXFs are included under docs/samples/oshcut/. weldbox frames are square-tube only, so rectangular, round, and pipe stock are intentionally left out.

Examples & docs

The winding machine cell gains a base plate; the epoxy machine cell gains 6 casters. FUNCTIONALITY.md section 6 covers both plate types, and the README and spec reference are updated.
