Sheathing Configuration

or:


Sheathing Configuration – allows you to configure and save settings for sheathing layouts. These settings can be saved and linked with roof layer using Link Roof.




Sheathing Dimensions


Sheathing Dimensions – predefine vertical and horizontal sheathing sizes (Width and Length).


Sheathing Layout


Sheathing Layout – predefine settings for Top and Bottom sheathing layers.


Up to two sheathing layers can be created from each side. That’s why there are separate settings for the first and second layer.


First and Second sheathing layers can be predefined in the Link Roof using Sheathing and Sheathing II from Framing Layer column.



Parallel or Perpendicular to Stud/Joist


Parallel or Perpendicular to Stud/Joist – select whether the sheathing should be parallel or perpendicular to the joist.


Build in Place


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



Bottom/Base Extension and Top/End Extension


Bottom/Base Extension, Top/End Extension – adds an offset from the roof base or end.


Sloped Top/End Extension and Sloped Bottom/Base Extension – adds an offset from the sloped roof base or end.


Placement Direction


Placement Direction – predefines sheathing direction: From Start, From End, or From Both Sides.



Second Row Overlap Distance


Second Row Overlap Distance – defines overlap distance between sheathing layouts if Perpendicular to Stud/Joist checkbox is ticked.



Align with Studs/Joists


Align with Studs/Joists – aligns sheathing with joists.



Allow to Split on Second King/Joist


Allow to Split on Second King/Joist – splits the sheathing on the second king or joist of the opening.




Always Try to Merge Parts


Always Try to Merge Parts – tries to merge parts if two parts share the same edge. Merged part size will not exceed the sheathing size that is predefined under Sheathing Dimensions.


Vertical Split on Opening Side


Vertical Split on Opening Side – splits sheathing on the opening side, the nearest joist, or the nearest king if top and bottom trimmers are predefined in the Opening Framing.


You can predefine top and bottom trimmers under Roof+MConfigs  Framing ConfigurationOpening Framing



Minimal Width of Opening for Split


Minimal Width of Opening for Split – define the minimum width of opening for which splits would be available. 


Example: If the opening width is less than the predefined value, then there will be no splits around the opening:


If the opening width is more than the predefined value, then there will be splits around the opening:


Horizontal Split on Opening Side


Horizontal Split on Opening Side – defines whether the sheathing must be split horizontally around the opening.


Example: Horizontal Split on Opening Side is ticked OFF:


Example: Horizontal Split on Opening Side is ticked ON:


Mark Settings


Mark Settings – predefine default values for these parameters for later use in schedules and tags.



Opening


Opening – predefine top, bottom, left, and right sheathing offsets from opening.



End Connection


End Connection – predefine sheathing settings for roof end connections.


Layer Extension – distance from roof face. 


Example: For the free end connection, Layer Extension = 20:

Split at Joist – define the joist number at which the sheathing must be split.


Example: Split at Joist = 1:

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



Excluded – removes the sheathing (part) from the model. Excluded sheathings are only visible when under the cursor and will not be included in schedules.
