Retaining Wall

Evidence scope

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.

BimSpeed.STR → Wall → Retaining Wall reinforces a straight wall. Curved walls are outside the described command scope.

1. Pick one Wall on a copy. Use two distinct axis points to restrict its length, or use the whole wall. Point order defines left/right; verify the diagram before creation.
2. Choose one or two layers. A single layer needs a side choice; ties connecting layers apply only to two layers.
3. Review three cover groups, vertical/horizontal bars and top/bottom ends. Scroll through the form and use Section / Elevation tabs.
4. Enable face strengthening or top/base boundary reinforcement only when required. Dependent settings affect the result only when enabled. For one layer, added face reinforcement follows that layer's side.
5. Create writes native Rebar. A ViewModel error makes the entry roll back its transaction. Existing tool-owned reinforcement can enter update mode: verify the host and existing groups first.

Exercises and verification

Keep diameter/cover fixed and try vertical spacing 200 → 150 → 250 mm: the count along wall length should increase then decrease. Horizontal pitch is checked over height. Test two layers → one and inspect the retained side, connecting ties and additional bars. These are proposed exercises, not successful committed cases from this pass.

Inspect Fine 3D, elevation and section views. Select representative vertical, horizontal, connecting and boundary sets for diameter, Spacing, Quantity and host. Save a separate result RVT and reopen it before treating it as output.

Settings

Control	Unit / choices	Effect and verification
Layers / single-layer side	1 or 2; left/right	Selects retained faces; connecting ties apply to two layers.
Current configuration / Save / Delete	Preset; buttons	Loading replaces multiple values. Saving a preset does not create bars; deleting it does not delete model reinforcement.
Top-bottom / side / start-end cover	mm	Three independent directions; inspect section and ends.
Top / bottom hook type and lengths	Shape; mm	Straight versus hooked ends; hook lengths apply to hooked branches.
Vertical type / spacing	Type; mm	Distributed along wall length; inspect the vertical set.
Horizontal type / spacing	Type; mm	Distributed over wall height; inspect separately.
Connecting type / horizontal / vertical spacing	Type; mm	Two-layer ties. A zero vertical pitch uses the legacy value of twice horizontal wall-bar pitch; verify output.
Top / bottom offset	mm	Vertical end setbacks; compare with host ends and cover.
Start / end horizontal offsets	mm	Axis end setbacks; depend on selected direction.
Additional bars / side / height	On/off; side; mm	Face strengthening. Single-layer mode forces the retained layer side.
Boundary reinforcement / position / region height	On/off; position; mm	Enables the top/base boundary group and its region.
Boundary main-bar type / count	Type; integer	Diameter and count of the boundary main group.
Boundary tie type / pitch	Type; mm	Bar size and tie density in the boundary region.
Section / elevation	Tabs	Input-derived diagrams; inspect native Rebar separately.
Create / Close	Buttons	Create/update depends on host state; Close does not create output.

Read the dialog and its dependent options

These are actual English tool controls in Revit 2024. The coloured section is an input diagram, not newly created native Rebar.

1. Select a preset, then check the fields; Save and Delete manage presets, not model Rebar.
2. The three covers act in separate directions and are entered in mm.
3. Cross Section and Longitudinal Section change the input diagram, not the Revit active view.
4. Read layer count, hooks and spacing on the diagram; height comes from the host.
5. Create writes/updates model elements; Close leaves the editor.

1. The top hook changes the bar end; Top Offset moves its placement. Check both.
2. The three Ø/@ rows control vertical bars, horizontal bars and connectors separately. The connector row also has a vertical pitch; zero selects the tool fallback.
3. Positive Bottom Offset extends the lower end below the host base; inspect cover, hooks and the real support region.
4. The bottom hook and its length are independent of the top hook.

1. Horizontal offsets are measured from the chosen axis start/end; recheck them when its direction changes.
2. Enable Additional Rebar before choosing its side and height. In single-layer mode the tool follows that layer side.
3. Enable the boundary group, select its top/bottom scope and enter the zone height in mm.
4. The boundary main-bar type and count belong to this zone, not the wall web.
5. Boundary tie type and pitch are separate; a smaller pitch increases this zone density.

Edit and save

After changing spacing, layers or extra groups, check both sections before Create. Keep a pre-update copy when the host already contains tool-owned data: regeneration may replace its stored reinforcement. Model Undo and preset loading are different operations. Save As the RVT after inspecting the bars, then reopen the result view.

Educational R24 wall input supplies an input host only; it is not Retaining output.

Cover, offsets and dependent reinforcement

The three covers act at elevations, wall faces and axis ends respectively. Positive Top/Bottom Offset extends vertical ends above/below the host; zero uses the cover branch. Positive horizontal start/end offsets extend bars beyond their corresponding axis ends. They are not additional inward cover. Inspect the supporting region and the whole native shape before accepting an extension.

Top and bottom hook choices are independent. Their lengths act only on the hook branch and add the illustrated horizontal leg; compare one end while holding the other fixed.

Additional face reinforcement derives diameter/distribution relationships from the original vertical group and has no independent diameter input in this panel. Too few vertical bars or a nonpositive added height can yield no additional group. In one-layer mode the effective side follows that layer.

Boundary Position selects top, bottom or both. Boundary height outside the usable range is replaced by the smaller of 500 mm and half wall height. Main-bar count is normalized to an even number of at least four; nonpositive boundary tie pitch can fall back to 200 mm. Read back the values rather than assuming every typed number is preserved.

The connector vertical pitch of zero uses twice the wall horizontal-bar pitch, not twice the connector horizontal pitch. Recheck connectors after changing horizontal web bars. Preset loading can replace values in disabled groups too; check them when re-enabling. Keep a pre-update copy because regeneration of stored tool groups need not retain every manual bar edit.

Requirement for model creation

The exercised Revit 2024 Release build displayed You are not logged in! during its command permission check and cancelled before creation. An open editor does not establish sign-in or creation permission. Use the normal BIMSpeed sign-in flow and check access to the exact command and Revit version before running on a copy. No generated, saved and reopened result has been verified for this command; its preview is not accepted output evidence.
