Column Rebar v2.0 — Settings reference

Existing walkthrough and UI captures. This reference is specific to Column Rebar v2.0; installed labels can vary. Bars were saved and reopened on an educational column, but one tie set was outside its host. Read the walkthrough result before reusing that configuration. Preview graphics and calculated summaries do not replace actual Rebar Quantity, diameter and host checks.

Hosts, geometry and layout

Control	Unit / condition	Effect and verification
Column / Level list	selection	Select the edited story. Use a single column or aligned stack of one section kind; independent columns belong in Multi-Column.
Cx quantity / Cy quantity	integer	Rectangular face counts include corners; perimeter total is 2Cx+2Cy−4. Increasing Cx adds bars on two corresponding faces.
D quantity	integer, circular hosts	Total bars around a circular section, replacing Cx/Cy. Check circular geometry before generating.
Main bar type	RebarBarType	Changes longitudinal bar diameter independently of count; inspect its Type Properties.
Main stirrup type / Additional stirrup type	RebarBarType	Independent main and additional tie types; their pitch settings are under Stirrup.
Reinforcement description / Area / Ratio	read only; count / area / %	Calculated layout summary, not a report of created model elements.
Distribution: L1 / L1,L2 / L1,L2,L1	mode	One uniform zone, two zones or end–middle–end. Inspect boundaries as well as pitch.
Single tie / Closed tie / section picking	mode + picks	Choose the additional-tie kind and pick bar positions in the section. Inspect the tie shape before Run; not every combination has been verified.
Delete all stirrup ties	action	Clears configured additional ties in the edited layout/preview; not a project-wide Rebar deletion command.
Framing/Floor height / Name	mm / association	Check intersecting framing depth and name; a number alone does not establish a valid association.
Top cover / Other cover	mm	Independent top and other-face cover. Increasing cover reduces the cage domain; measure the model section.
Apply for other levels	action	Choose Main Rebar and Stirrup independently for target stories. The source row is disabled; Section/Base/Top are read only. Apply copies settings without generating reinforcement.

Main and additional ties

Control	Unit / condition	Effect and verification
Spread to bottom / top of Framing/Floor	mode	Chooses the tie termination boundary at the intersection. Spreading to the top exposes intersection distribution settings.
Seismic stirrup: Spacing / Quantity	mm / integer; intersection branch	Choose pitch or a fixed count in the framing zone. These are different input modes; verify actual count.
Starting offset	mm	Distance from region boundary to the first tie; not tie pitch.
A1 / A2	mm	End/middle pitches. Reducing A1 increases density in its zone without increasing longitudinal bars.
L1 minimum / value	toggle + mm	Enables the minimum end-zone length candidate.
Clear height / Division factor	toggle + divisor	Enables clear height divided by the factor. The largest enabled candidate governs.
Column section height	toggle	Adds section depth as an L1 candidate; this is not story height.
Cover splice zone	toggle	Extends the dense tie zone over the splice according to tool rules; compare with actual lap locations.
Separate top zone / Top zone length	toggle + mm	Enables an independently sized top zone; otherwise the common rule applies.
Main stirrup hook type	RebarHookType	Select a loaded main tie hook; inspect the resulting hook type and angle.
Follow main stirrup spacing	toggle	Additional ties follow main tie distribution. Disable for independent pitch.
Additional spacing / Hook type	mm / RebarHookType	Independent pitch applies with Follow Main disabled; hook type belongs to the additional-tie role.

Foundation dowels

Control	Unit / condition	Effect and verification
Starter Bar Settings	toggle	Enables dowels; check actual footing and column base geometry before Run.
Separate two segments	toggle	Separates dowels from column bars; count both segments by role.
Foundation stirrup / spacing	toggle + mm	Enables ties in the footing region and sets their pitch.
Hm / Lb	mm	Vertical and anchorage-leg dimensions shown in the diagram. A bounding box containing blinding is not the structural concrete thickness.
Left / Right / Back / Front / Reverse	actions	Changes individual legs or reverses their common direction; inspect plan and elevation.

Anchorage, laps, metadata and execution

Control	Unit / condition	Effect and verification
Head hook: Fixed length / Diameter factor	mode + mm / ×D	Use a fixed length or diameter multiplier for the hook; only the active mode applies.
Head lock / Continue as starter	mode	Top anchorage or continuation as a starter; inspect the highest column end.
Add elevation / Add Partition	toggles	Writes metadata; inspect Properties. Does not directly change bar counts.
Lap coefficient / Anchorage coefficient	×D	Independent lap and anchorage multipliers based on longitudinal bar diameter.
Crank at splice	toggle	Cranks bars at laps; inspect the resulting splice geometry.
Group same Rebar Number / Parameter name	toggle + parameter	Aggregates quantities into the selected parameter; a suitable writable parameter is required.
Max e / Hd:e / Crank by ratio	mm / ratio / toggle	Section-offset and ratio conditions for cranking/termination, distinct from cover and lap multipliers.
Splice from bottom / Middle	mode	Selects a bottom-based or available-clear-height middle splice reference.
Bottom offset	mm; bottom mode	Distance from the column base to the splice in bottom-based mode.
One / Two splice positions; separation	mode + ×D	One splice level or two staggered levels; separation is in bar diameters, not millimetres.
Framing/Floor: default / manual / automatic	mode	Use default depth, manual hosts or automatic discovery. Manual mode enables Select Framing/Floor and Finish.
Default framing height	mm; default mode	Used by the default-depth branch; compare with actual framing.
Run / Close / tabs	actions	Run saves configuration and creates Rebar; Close exits and tabs navigate settings. Inspect 3D output and save the RVT. Do not assume repeat runs replace manually created bars.
