Member Information
System Name	Specifies a data file to use for joist frames.
Model Filter	Select Show Only Producible to limit the Model Name field to joist members that can be made with the roll-former selected in Machines Used.
Model Name	Sets the joist system (e.g., webbed joist, deep-c), and the profile width and shape, and material thickness and grade to use for joist members.
Joist Type	Specifies what to use for side bearers. Side bearers sit at the perimeter of the frame, parallel to standard joists, and do not typically carry joists.
Side Bearer Type	Specifies what to use for side bearers. Side bearers sit at the perimeter of the frame, parallel to standard joists, and do not typically carry joists.
End Bearer Type	Specifies what to use for end bearer members. An end bearer sits at the perimeter of a frame, perpendicular to joists, carrying the terminal ends of standard joists.
Int Bearer Type	Specifies what to use for internal bearers. An internal bearer sits perpendicular to joists and carries terminal ends of joists on both sides.
Machines Used	Sets the roll-formers that will be used to make joist frame members.
Member Height Override	Sets a value to use instead of the height that is automatically derived from sizing rules (for webbed joists only).

Layouts Information

Joist Spacing

Sets the maximum distance allowed between the center of one joist and the center of the next.

Int Bearer Spacing

Sets the maximum distance between one bearer and the next.

Ceiling Batten Spacing

Sets the spacing of ceiling battens along the bottom of joists. Used for bottom chord restraint engineering calculations. Note: A value is required if you want to include batten material in the floor member summary in a border when you type JD to add a joist.

Reduced Level

Sets the height of the floor system measured from the ground level of the structure to the top chord of the joist. Critical for detailing joist layouts in association with wall framing. Value must be < joist depth, +/- 100mm (3 15/16") of wall height before loads are able to be transferred.

Bearers Method

Option	Info
Bearers Inline	Places bearers in line with or under joists.
Bearers Under	Places bearers in line with or under joists.
Blocking	Places a short blocking member in every gap or in every other gap between joists.
Alternate Blocking

Internal Bearer Method

Double Int Bearers

Sets each internal bearer to consist of two back-to-back members.

Oncoming Web Align

Aligns vertical webs with oncoming members (for fixing purposes).

Double Webs to Supports

Places two vertical members in a webbed joist at each edge of an underlying support line (as determined by the line’s support width).

Type LI and select the support line to adjust its support width.

Layouts Colour

Sets the color to use for joists.

Tooling Options

See Panel setting command for info.

Applied Loads	In kPa (metric) or psf (imperial) except where noted.
Dead Load	Dead and live loads of a floor that will be applied to a joist.
Live Load
Ceiling Load	Dead load of a ceiling that will be applied to the bottom chord of a truss.
Snow Load	Snow load of a roof that will be applied to the top chord of a truss.
Design Point Load	Vertical load applied to a point on a joist in kN (metric) or kip (imperial).

Deflection Limit
Deflection Limit (Live)	Preset engineering values.
Deflection Limit (Dead + Live)
Max Allowable Deflection

Ceiling Battens Information	Used for BOM purposes only, not for modelling.
First Ceiling Batten	Defines the material and profile to use for the first batten in a truss.
Next Ceiling Batten	Sets the profile section to use for all subsequent battens.
First Batten Length	The length of the first batten in a truss.
First Batten Lap	Length of overlap between first batten and an adjoining batten.
Next Batten Length	The length of all subsequent battens in a truss.
Next Batten Lap	Length of overlap between two adjoining subsequent battens.
End Screw Type	Type/number to use when fixing the ends of a batten to a frame.
End Screw Frequency
Int Screw Type	Type/number to use to fix internal battens to supporting members.
Int Screws per Crossing

Creation Options
Auto Cutting List	Includes a floor member summary in border in Layouts if joists are labelled.
Auto Label Members	Adds labels to joist members in the layout.
Preserve Floor Outline	Keeps the floor outline in the layout.
Auto Floor Sheet Layout	Includes a floor sheeting layout using Sheeting Information settings in Options tab.

Report Options	Sets information to include about joists when you type REP.
Select True to for each to include joist Members, Connection Brackets, Connection Fixings, Weight, Battens, and/or Batten Fixings.

Labelling Option Information	(Sets labels and info that appear in a border when you type JD)
label prefixes	Sets what prefix to use in labels for joists, for end, side, and interior bearers, and for bearer beams.





Restart Zone Labels	Restarts from 1 for each zone (if zones are set) (instead of numbering continuously across all set zones).
Include Joints	Includes labels when identical members join other members differently or when identical members have different service holes.
Include Service Holes
Use Continuous Numbers	Counts from 1 and continues for all joist types (instead of restarting at 1 for each joist type).
Collect Common Member	Shows a quantity for members of equal length (instead of listing all members separately) in a Floor Member Summary.

(Sets info to include in detail sheets in joist detail spaces)

Include Materials

Adds a bill of materials showing the material, quantity, and length of each member required for the respective joist frame.

Collect Common Lengthts

Lists members in the BOM (and labels members in the elevation view) by common length.

Include Parts

Lists type and quantity of connectors and other parts required for the joist frame.

Include Design Summary

Shows design and load codes, wind speed, and other joist frame design parameters (at bottom of detail sheet).

Show Major Dimensions

Includes dimensions for overall size, layout, and geometry.

Show Minor Dimensions

Includes size, position and spacing of components.

Option	Shows any dimension as...
Traditional	the distance between two points
Ordinate	the distance from one point

Show Reactions

Includes reaction values at support points.

Show Percentages

Shows what percentage of the joist frame’s load capacity is being used (instead of just Pass or Fail). Greater than 100% counts as an engineering failure.
