Framing Configuration may be found in two locations:


or:


You can add eight different types of continuous or non-continuous Joists, Rafters or Bridging into framing using different rules.



Type – select the family and type that will be used for Joist/Rafter/Bridging. 


Width (b) – shows b size of selected type.


Depth (h,d) – shows h or d size of selected type. 


Define Depth (h,d) by Layer Thickness Roof+M will automatically create new type for selected family with new depth equal to selected roof layer thickness. 


Apply J/R/B (Joist/Rafter/Bridging)



Apply J/R/B (Joist/Rafter/Bridging) – choose whether or not the rules listed below should be applied to the frame.


Rotate by Slope


Rotate by Slope – Joist/Rafter/Bridging can be rotated according to roof slope.



Rotate 90°, Rotate 180°


Rotate 90°, 18 – Joist/Rafter/Bridging can be rotated 90/180 degrees from it's initial position.



Apply by Roof Type



Apply by Roof Type – option to add Joist/Rafter/Bridging only for Structural, Non-structural, or Always selected roofs in the project. Usually used for floors and walls. 


Use Short Noggings



Use Short Noggings – select if noggings have to split between the joists.


Cut Type


Cut Type – select Joist/Rafter/Bridging cutting type.

 


Cut Ends Type


Cut Ends Type – select Joist/Rafter/Bridging end cutting type.


Diagonal Placement


Diagonal Placement – options to place Joist/Rafter/Bridging parallel to top/bottom sloped rim joists or parallel on horizontal rim joists. 


Example: Blocking is placed parallel to top sloped rim joist:


Array1 or Array2


A set of rules for placing many Joists/Rafters/Bridging.



Array 1 or Array 2 – there are options to apply three array rules: Array from Base, End or Center of the frame.


Frame Side


Frame Side – select whether Joist/Rafter/Bridging should be applied in the center, external (top), or internal (bottom) side of the frame. 



Top/Bottom Plate Support (Auto)



Top/Bottom Plate Support (Auto) – option to add top/bottom plate/joist supports and align with top/bottom rim joist automatically. In such cases, the Offset from End/Base Face option is not available because it is calculated automatically.

 

Offset from Base/End – Joist/Rafter/Bridging offset from top or bottom rim joist top face.


Spacing – spacing between rows of Joist/Rafter/Bridging.


Number – the number of Joist/Rafter/Bridging rows.


Measure to


Measure to – measures the offset and spacing to Joist/Rafter/Bridging top/bottom or center. 


Build in Place


Build in Place – writes Yes/No information into the Joist/Rafter/Bridging instance parameter if it is build-in-place or is prefabricated with the whole roof frame. Later this parameter can be used in schedules or view filters.



Bays


For First&Last Bays – select if bays should be applied for both sides of roof.


Number of Bays – number of bays from both roof sides.


Use Alternating Offset


Use Alternating Offset – use linear (no offset) or alternating offset of Joist/Rafter/Bridging rows.


Placement Limits

Placement Limits – Joist/Rafter/Bridging placement. It can go: Throughout the frame, Throughout except all Openings, Only through all Openings, Only through Windows, Only through Doors, or Only through Openings.



Example: Here is bridging added automatically only above the opening:


When Opening Width is over and When Opening Width is less than – here you can predefine the opening sizes for placing Joist/Rafter/Bridging. For example, big openings can have additional bridging above or below.


Cross Diagonal Cripple Joists


Cross Diagonal Cripple Joists – select if Joist/Rafter/Bridging should go through diagonal cripple joists.


Cross Sloped Rim Joists


Cross Sloped Rim Joists – select if Joist/Rafter/Bridging should go through places with sloped rim joists.
