Add/Modify Bracing – features for adding/modifying braces between joists or rim joists, corner braces and brace groups.
Modify Brace – modifies selected brace in the frame.
Type – select the family and type that will be used for brace. Default family is M_MF Strap.rvt (for Metric projects) and I_MF Strap.rvt (for Imperial projects).
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+ will automatically create new type for selected family with new depth equal to selected roof layer thickness.
Rotate 90° – brace can be rotated 90 degrees to its initial position.
Example: when Rotate 90° is switched OFF:
Extend Ends – extends brace ends when it connects to other elements.
Example: when Extend Ends is switched ON:
Example: when Extend Ends is switched OFF:
Rotate 180° – brace can be rotated 90 degrees to its initial position.
Mostly used for non-symmetrical wooden profiles or metal braces.
Minimum/Maximum Angle – define angle limits for adding a brace.
Cut Joists – select brace and joist connection cutting type.
Possible options: Don't Cut, Cut Joists, and Cut Bracing.
Example: when Cut Joists is selected:
Cut Bridging/Nogging – select brace and bridging/nogging connection cutting type.
Possible options: Don't Cut, Cut Bridging/Nogging/Blocking and Cut Bracing.
Example: when Cut Bridging/Nogging/Blocking is selected:
Brace Connection Offset from Joist/Rim or Bridging/Nogging/Blocking
Brace Connection Offset from Joist/Rim – brace offset from connection point with a joist.
Brace Connection Offset from Bridging/Nogging/Blocking – brace offset from connection point with a rim joist, bridging, or nogging.
Example: when Brace Connection Offset from Joist/Rim = 100:
Special options for corner braces:
Placement Type – select a corner brace placement type: by offsets or fixed angle.
Angle – define corner brace placement angle if Placement Type = Fixed Angle.
Example: when Placement Type = by offsets and Brace Connection Offset from Joist = 400, Brace Connection Offset from Bridging/Blocking/Nogging = 300:
Example: when Placement Type = Fixed Angle, Angle = 45 and Brace Connection Offset from Joist = 400:
Frame Side – select whether a brace should be applied in the center, external or internal side of the frame.
Example: when Frame Side = Center:
Example: when Frame Side = External:
Build in Place
Build in Place – writes Yes/No information into the brace instance parameter if it is build-in-place or is prefabricated with whole roof frame. Later this parameter can be used in schedules or view filters.
