OptionDescriptionDefaultOther

Direction of Spring Fixes
(Top-> Bottom, Bottom-> Top, Default)
This defines how the spring fixes are fitted. For example, going up the roof top->bottom would cause them to be fitted between the top hole of the first purlin and the bottom hole of the second purlin.The default direction will be determined appropriately from the roof pitch data to give the standard CMF arrangement for the bay length. 
Type of Anti Sag (Anti Sag Ties, Angle Brace, Threaded Rod)This specifies the type of connecting member to be used for the anti sag. The default is set to Anti sag Ties. 
Rule Type
(Standard, Barrelled)
If Standard rule type is selected more restrictive checks will be used to ensure the purlins are aligned correctly.The default is set to Standard. 
Add Offset Hole Pair
(No, Yes)
This defines whether to place an extra pair of holes on each purlin connection when an offset value is defined.The default is set to No.

Number along the bayThis specifies the number of struts to place along the bay (as defined by the two rafters).This value will come from the data files. 
Place Diagonal Tie Wire atThis sets the position where diagonal tie wires will be added. This is writen as a list of bay numbers for example, 1 3 would put diagonal tie wires in the first and third bay (see image). A brace must be placed in the bay that needs a tie wire. The default behaviour is to not place any tie wires.

General Bolt GradeThis sets the standard for all bolts added by the macro excluding those which may be placed to the web of the eaves beam. The default setting is 8.8XOX. 
Eaves Bolt Standard
 
This sets the standard for bolts placed to the web of the eaves beam. If this standard specifies countersunk bolts then a suitable packing plate will be added.The default setting is 8.8XOX. 
GroupThis defines the class that all parts will be included in.The default setting is 99.
