Add/Modify Elements – features for adding/modifying additional joists, support joists, bridging/nogging elements, etc.
Add Additional Bridging/Nogging/Blocking
Add Additional Bridging/Nogging/Blocking – adds additional bridging/nogging/blocking between two selected joists with predefined settings.
Additional Bridging/Nogging/Blocking sizes
Type – select the family and type that will be used for Bridging/Nogging/Blocking.
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.
Rotate by Slope
Rotate by Slope – rotates additional bridging/nogging/blocking by roof slope.
Rotate 90° – Bridging, Nogging, or Blocking can be rotated 90 degrees to its initial position.
Use Short Noggings
Use Short Noggings – makes short noggings between the joists, instead of long ones.
Example: Use Short Noggings is switched ON:
Cut Type – select blocking/nogging/bridging and joist connection cutting type.
Example, when Cut Type = Cut Additional Element
Select Line-Based Element
Select Line Based Element – adds blocking/nogging/bridging according to selected line-based element.
Offset from Selected Element – writes an offset for adding blocking/nogging/bridging from selected line-based element.
Example: when Offset from Selected Element = 0, Select Line-Based Element = opening header:
Example: when Offset from Selected Element = -200, Select Line-Based Element = opening header:
Split Studs/Joists – splits joists near inserted blocking/nogging/bridging.
Example: when Split Studs/Joists is switched ON:
Note: Split Studs/Joists is available ONLY IF Use Short Noggings is switched OFF.
Offset – predefines the offset rule (from shorter or longer joist end or base. This function works for joists that are not split. It is especially used with sloped roofs.
Joist base is at the top of the roof, and end is at the bottom of the roof.
Offset from Base/End – predefines the offset from top or bottom of the joist.
Spacing – distance between blockings/noggings/bridgings.
Number – number of blockings/noggings/bridgings.
Measure to – measures the offset and spacing to bridging/nogging/blocking top/bottom or center.
Frame Side – choose whether nogging should be applied in the center, external, or internal side of the frame.
Build in Place
Build in Place – writes Yes/No information into the blocking/nogging/bridging instance parameter if it is build-in-place or is prefabricated with whole roof frame. This parameter can later be used in schedules or view filters.
