Frame Rebar
The images identify controls in the exercised build. Read the version and run limitations below before applying the workflow. Proposed exercises are not verified results; no accepted result-model download is available for this tool.
Frame Rebar reads one vertical frame from native beams/columns and calls Beam Rebar/Column Rebar engines. Start in a 3D view. Locate BimSpeed → Thép khung → Thép khung. When the host already has BimSpeed.STR but no BimSpeed tab, the module uses BimSpeed.STR → Thép khung. A compatible Frame module must be loaded for the button to appear.
- Select straight horizontal beams and vertical rectangular columns sharing a frame plane. Preselection or command-time selection is supported. Hosts must be free of Rebar; narrow the scope if already reinforced.
- Select a member on the left. Edit its column/beam fields in the middle. Apply to member updates that member; Apply to all of the same type updates all columns or beams in scope.
- Check / view real bars creates trial bars through the engines, reads their centerlines/quantities, then rolls back. Successful elevation/data tabs describe that trial; those bars are not retained in the model.
- Read engine notes and inspect storey diameter/count changes. Changing inputs or model geometry invalidates the previous check; check again before creation.
- Choose whether to create Section, sheet and Schedule, then Create. Close the editor after success to inspect the model. The sheet has no title block and is not a full shop drawing set.
- Inspect Fine 3D, elevation and Schedule. Select representative bars on each storey for diameter, Quantity, Spacing and host. Save As and reopen the result.
Counts and scope
Column edge counts include two corners: total longitudinal bars = 2 × (Cx + Cy) − 4. Cx=4, Cy=4 gives 12 bars, not 16. Rebar-element count differs from summed set Quantity. The table reports individual objects, total length and approximate mass using 7,850 kg/m³; it is not procurement/cutting weight.
Newer versions include storey-specific column diameter/count behavior; the binary pictured here requires a shared column-stack configuration. Read the installed build’s Rules tab before editing by storey. In a build that supports those changes, cover, tie pitches and lap/anchor factors still follow shared stack rules. Offset members still need their sections to intersect the common plane. Curved/sloped beams and noncoplanar frames are outside this scope.
Trial, CSV and saving
CSV records Trial rolled back / Committed. Trial IDs are not persistent model elements. CSV export does not create a Schedule. The optional native Schedule filters the operation identifier, not all project reinforcement. Empty data after a failed/licensing-blocked operation does not establish zero reinforcement in the actual frame.
The 23 October 2026 images remain historical UI/validation evidence. They do not establish current login state or successful creation. Read the new evidence limits below.
Settings
| Control | Unit / choices | Effect and verification |
|---|---|---|
| Member list | Selection | Chooses the edited host; inspect label/tooltip Id. |
| Cover | Integer mm | Cover; committed creation can update column cover. |
| Column longitudinal / beam top diameter | Integer mm | Host-dependent field; matching bar type required. |
| Cx / Cy | Integer, corners included | Columns only; longitudinal count = 2(Cx+Cy)−4. |
| Column lap / anchorage factors | × diameter | Lengths follow diameter; inspect storey size transitions. |
| Top count / bottom diameter / bottom count | Integer; mm | Beam-only upper and lower groups; inspect separately. |
| Additional bars from Beam Rebar preset | On/off, beams | Preset-dependent bars; read warnings and compare trial/commit. |
| Tie diameter / end pitch / middle pitch | Integer mm | Independent tie size and regional pitches. |
| Apply member / all same type | Buttons | One host or all selected columns/beams, without crossing types. |
| Elevation / data / rules / notes | Four tabs | Host diagram before trial; Rebar data after trial; scope limits and warnings. |
| Create Section/sheet/Schedule | On/off | Optional model documentation, independent of CSV. |
| Check / Create | Buttons | Trial rollback first; creation enabled only after a valid check. |
| CSV | Button | Exports current result with state; requires a result. |
| Fit frame / focus member | Buttons | Viewport fit or selected-member focus; no geometry edits. |
| Wheel / middle drag / double-click | Zoom / pan / fit | Canvas navigation; resizing returns to fit. |
| Close | Button | Exits editor to inspect result; save the RVT separately. |
New evidence — 24 October 2026
Revit 2027.3 opened a model copy and read 2 beams and 8 column segments. The production editor and its tabs opened. Preview stopped with “Beam Rebar chưa được cấp phép” (Beam Rebar is not licensed). Successful trial rollback and committed creation were not reached; no new Frame result RVT is available. This was an isolated module-check session; the message does not establish the account entitlement in a normally signed-in BIMSpeed session.
The exercised binary's Rules tab requires a shared column-stack configuration, while newer versions include storey-specific diameter/count behavior. That newer behavior is a reference capability, not a successful result from this binary. The tool UI remained Vietnamese; Vietnamese screenshots are not presented as English UI evidence here.
When preview is disabled or an engine permission fails
Frame uses the Beam Rebar and Column Rebar engines loaded with the package. Use the normal BIMSpeed sign-in flow, confirm those engine permissions and use modules compatible with the same Revit version. Opening the editor does not establish permission to execute an engine. Preserve the input and error when Preview fails; empty tables/CSVs do not mean the real frame has zero reinforcement.
The exercised Revit 2027.3 build requires a shared configuration along a column stack. Storey-specific diameter/count behavior in newer builds must be checked against the actual version; do not apply it to an older Rules panel that states otherwise. Verified English tool UI is unavailable for this build.
Deliberate changes
For columns, Cx=4/Cy=4 predicts 12 longitudinal bars; Cx=5 predicts 14 and Cx=3 predicts 10. Apply to the intended host/type, Preview again and inspect that column section. For beams, change top count independently of bottom diameter/count. Tie diameter and end/middle pitch affect different properties/zones.
Compare lap multipliers at a fixed diameter before changing diameter itself. Inspect storey-junction elevations, not only mid-storey sections. Applying edits invalidates the old preview, so Preview again before Create. After creation Save As/reopen and select committed IDs; rolled-back trial IDs are not model elements.
These are verification exercises for licensed engines and valid inputs. The exercised build did not complete trial/commit; no accepted output model download is provided.
