New Wall Rebar (TCVN)

This guide opens an actual Revit 2024 wall model, checks the layout and regenerates reinforcement for one core, five branches and eleven stories. All new screenshots were captured full-screen with the English UI. Model level/core/template names retain their original project names. Click an image for its original resolution.

Download the actual result model (.zip, Revit 2024) · Unreinforced practice-model pack · All 86 fields in 14 settings groups · Bar-count changes and regeneration.

1. Open the model and find the ribbon command

1. Extract and open Wall-Rebar-Result-Revit-2024.rvt in Revit 2024 or newer. Save As a practice copy. The file also contains another sample core; this run regenerated only the selected core. View {3D} already isolates V2 between L8 and L9.
2. To start without reinforcement, use 01-Thep-vach-Revit-2024.rvt from the practice pack. Select one concrete wall in the connected core, rather than selecting every story.
3. Click BimSpeed.STR → Wall → Wall Rebar, not the adjacent Shear Wall command. If prompted, select walls and click Finish. For several cores, select a representative wall in each.

① BimSpeed.STR; ② Wall Rebar; ③ selected model wall. The command recognizes connected branches, openings and story stacks from this selection.

2. Main window: select the scope before editing

Maximize using the top-right square button. Selected V2 is 8,400 mm long, changes from 300 to 250 mm thick and has two 1,100×2,200 mm openings. The header confirms 1 core, 5 legs, 11 storeys.

Mark	What to click and read
① Cores & legs	Tick the intended core/branches; click a branch to inspect it. Search filters names/grids. All / To review / Created filter the list. + Add walls / cores… returns to Revit selection; Skipped explains excluded elements.
② Plan / Elevation / Boundary / 3D	Switch layout previews; switching tabs does not create Rebar.
③ Properties	Select Project / Core / Story group / Leg / Storey, or a zone on the canvas. Read the scope description before editing. ○ means inherited; an override has a reset action. Fields unavailable at this level must be edited at a broader allowed scope.
④ Storey table	Double-click a reinforcement cell for a story-specific override; blue cells are overrides. Group storeys… manages groups; Copy storey → storeys… copies settings to chosen targets. Quantities and Checks show summaries and issues.
⑤ Create rebar	Writes the checked cores to Revit. Save settings persists configuration only. Close exits. Stop appears while writing; read the retain/rollback prompt before choosing.
⑥ Storeys / Standard / Seismic	Set the run's first/last story, standard and seismic level. Material/lap information reflects the configuration; edit it at the correct Properties/profile scope.

Undo reverses settings edits in the session. Layout templates… selects a reusable arrangement. Detailing standard… opens all 86 fields: choose Profile, Duplicate for a separate copy, Rename/Delete where allowed, Export/Import JSON for sharing, Apply to project to assign it, Save to persist the profile, Cancel to discard edits and Defaults to reset values. Review narrower overrides after applying a profile.

Create drawings & sheets (P2) is disabled in this build; it does not produce drawings.

3. Change reinforcement and inspect its effect

Select the intended Leg/Storey/Zone first. This example has Ø14a150 vertical web bars, Ø12a150 horizontal bars, 8Ø20 boundary bars, Ø10a100/150 boundary hoops and Ø8 2×2 S-ties. These are practice-model values, not universal project defaults.

Change	Control	Inspect
More/fewer vertical bars	Vertical web bars → Max spacing a: 150→100 is denser; 150→200 is less dense.	Plan dots, counts and mass; actual spacing depends on distribution.
More/fewer horizontal rows	Horizontal bars → Spacing a; also check First bar above slab s0 and Continue through slab zone.	Elevation rows and the slab zone.
Different diameter	Diameter in the correct web/horizontal/boundary/tie group.	Mass, clearances and laps; diameter does not directly set count.
More boundary bars	Boundary elements → Bars per face nX, e.g. 4→5.	Count per face, lc and restraint of every bar.
More hoops	Reduce Hoop spacing inside hcr a1 or outside hcr a2.	Hoop density in the corresponding zone.
More S-ties	Reduce every-N vertical/horizontal values, e.g. 2×2→1×2.	Ties layer and tie density; diameter is separate.
Different splice/base/top	Vertical bar laps / Wall base / Wall top / Story transitions.	Lap elevations, staggering, foundation feet, top anchorage and terminating/dowel bars.
Opening reinforcement	Openings & lintels: trim bars, diagonal corners, jamb boundaries, lintel top/bottom bars and hoops.	Opening edges and anchorage into the side walls.

Use the complete 86-field reference for options, units, deepest edit scope and output effects. Each group has an actual English UI screenshot with marked input areas.

4. Elevation, boundary sections and 3D buttons

Elevation

Click Elevation and use Storey ▼/▲ to choose a story. Full height shows the whole branch height. Vertical / Horiz. / Ties / Laps / Dims control preview visibility; hiding a layer does not delete bars. Use Fit, −/+, wheel zoom and canvas drag. This image shows two openings, foundation starters and staggered A/B laps.

① Elevation tab; ② opening and base details; ③ accompanying section/lap dimensions; ④ boundary controls to compare against the section.

Boundary

Click an end/junction zone on Plan, then Boundary; choose another zone in the canvas dropdown if needed. Click Fit if the section is outside the frame. Inspect bar dots, closed hoops, C-ties and horizontal layer order. Read Quick checks beside the section.

① Boundary tab; ② L-node section and restraints; ③ Quick checks. This local section is not the entire core bar count.

3D preview inside the tool

Click 3D immediately after Boundary. Choose Story and Scope (story with laps from below, or another available scope). 3D / Top / Front / Side changes the camera; Vertical / Horiz. / Ties / Laps filters layers; Fit frames the scene. Left-drag orbits, right/middle-drag pans, the wheel zooms and clicking picks a bar. Heavy scenes show a simplified view notice for reduced display detail.

① 3D tab; ② story/scope; ③ camera and layers; ④ planned cage. Use Create rebar to write actual Revit elements.

5. Check, create and read the report

1. Click Check. A trial write is rolled back to detect Revit writing errors. Open Checks below the canvas. Go to locates the issue in 2D; 3D locates it in the preview.
2. The sample reports WALL_THIN at V4–L1: 200 mm thickness is below its 225 mm check threshold. Notes include COVER_MISMATCH (Revit cover 40, tool 25), COUPLING_BEAM and SPACING_CHANGE at thickness transitions. This is an instructional model with issues requiring engineering review, not an approved design.
3. After reviewing scope/settings, click Create rebar · 1 core(s). If edited tool-owned bars are detected, Yes retains them, No overwrites from the plan and Cancel stops. This practice-copy run chose overwrite.

① Check; ② detailing warning; ③ notes and location buttons.

The actual run completed with 3,508 Rebar sets, 41,034 bars and 57,941.3 kg, 0 creation errors / 1 warning. These totals are for one core in this run, not both cores in the file. ① Run totals; ② by-diameter quantities; ③ Select in Revit, Export CSV…, Close. The reported mass belongs to this example model.

6. Actual reinforcement in a Revit view

Close the report and tool. In South, select the wall between L8 and L9 and type BX — Selection Box: Revit opens {3D} and fits its section box around the selection. Press Esc to deselect and zoom with the wheel. In the downloaded result file, directly open Project Browser → 3D Views → {3D}.

① Actual reinforcement around the two door openings at L8–L9; ② Detail Level=Fine and enabled Section Box; ③ {3D} view. Toggle Thin Lines (TL) for dense cages. If concrete obscures bars, select Rebar → Properties → View Visibility States → Edit and enable Unobscured for the view; do not hide the entire Structural Rebar category.

Close-up: ① end/jamb cage; ② above-opening/lintel bars; ③ vertical, horizontal and confinement steel in the middle pier. Inspect individual stories with Section Box before judging anchorage and laps.

The selected set's Properties shows D18, Partition Lõi 1–V2, Quantity=2, Spacing=230.7 mm. This is neither the web mesh pitch a150 nor the total wall count. Compare the correct reinforcement role and location when checking a setting.

7. Edit again and save

Reopen Wall Rebar from a wall in the core, edit the correct scope, then Check → Create rebar to update tool-owned elements. Save settings does not replace Create rebar. Save the practice file with Ctrl+S after inspection. Disable Section Box or open South to see the whole model again.

Download the result model with the prepared 3D view. Its README records scope and warnings. The tool assists detailing; an engineer must still verify strength, cracking, anchorage/laps and seismic design requirements.
