U-Boot Slab Rebar — create and inspect native steel

Open U-Boot Slab Rebar with one eligible structural concrete Floor. This writer creates straight top/bottom mats and U-Boot longitudinal rib bars; it does not automatically create shear stirrups.

Geometry workflow · Every setting/action, unit and enabling condition

Create on one host​

  1. Review Floor eligibility, material and actual cover. U-Boot/Bubble need matching product geometry.
  2. Enable Top/Bottom and X/Y; set diameter/pitch, nearest-face order and layer clearance. Inspect each face in Steel review.
  3. Resolve actual Rebar types by group. Read quantities, diagnostics and audit.
  4. Check Revit readiness, then Create / Update steel. Recheck readiness after edits.
  5. Inspect actual Revit 3D at Fine detail. Select representative bars and check Host, Type, Quantity=1 for each single bar, and length. Compare host/group totals.

Update and exercise​

Increasing pitch reduces density; reducing pitch increases it, while holes/regions can split bars. Updates replace owned bars rather than duplicate them. Preserve FOREIGN_REBAR, LEGACY_OWNERSHIP and PHYSICAL_UNIT_CLASH diagnostics and inspect ownership/actual solids.

Mark 1 encloses actual document type mappings after scrolling. U-Boot also includes Ribs.X/Y. Map every enabled group to the required diameter, then check Revit readiness. Similar names do not establish matching diameters. This shows configured production UI and service readiness, not the entry/selection chain. Mat, rib and readiness walkthrough.

Verified Revit 2024 result​

Installed package 2026.10.23.2046, exercised through its production reader/planner/writer. Ribbon picking, entry authorization and the complete entry flow remain untested. Educational host 498790 is a 5000 × 4000 × 400 mm concrete Floor with a 700 × 700 mm opening. Pre-existing reinforcement on other hosts is outside these totals.

Final centerline length: 96.161 m; Top.X=4; Top.Y=4; Bottom.X=4; Bottom.Y=4; Ribs.X=6; Ribs.Y=7. Each element has Quantity=1. The saved model was reopened and persistence, unchanged host and scoped ownership were checked. Test values exercise geometry rather than approved design.

Marker 1 identifies the settings/report in the UI, actual geometry in the overview and the selected bar’s Properties in the final image. UI images show loaded settings before an entry readiness action. The U-Boot sample bar is 4909 mm long, type 10-A-II, hosted by a Floor, Quantity=1.

Revit 2024 input/native-steel output package. Save a separate working copy and open MUSHROOM_MATS_ZONE_HOLES_STEEL_3D, UBOOT_MATS_RIBS_HOLES_STEEL_3D or BUBBLE_MATS_HOLES_STEEL_3D. The result includes all three test hosts; the input predates their creation. Read the README before reuse. Raw settings are reference data; spatial zones require host review.

Limit: full entry/picking remains untested. The scrolled type mappings above use the actual English module UI.
