Framing Tools: Sheathing

Tool for the sheathing layer (SHEET, SHEATHING) of a horizontal structure or horizontal structure panel. Select Tool from the list. The parameters are set according to the selected tool. If necessary, edit the parameters in the dialog box. The parameters define the sheet sizes, sheathing direction, alignment, etc. The following sheathing tools are included in the basic software delivery:

• Continuous (CONTINUOUS) - A continuous sheathing style to minimize material waste. The sheathing seams are placed so that the left over parts are utilized in accordance with the spacing of the framing. Parameter Overlap = Spacing.
• Staggered (OVERLAP) - This option makes the sheet seams overlap. Parameter Overlap = Half.
• Grid (GRID) - The sheets are positioned in the sheathing area so that their seams are continuous. Parameter Overlap = None.

Sheathing Rules

Overlap

The overlap is set according to the selected tool. If necessary, you can change the overlap.

Continuous (CONTINUOUS) - Overlap = Spacing, Rotate = 90, Align = Left.

Staggered (OVERLAP) - Overlap = Half, Rotate = 0, Align = Left.

Grid (GRID) - Overlap = None, Rotate = 0, Align = Left.

Sheet code

Select the sheet by clicking Sel.

Select the sheet library and double-click the desired sheet in the browser.

You can first narrow your search results with the column filter function. Set a filter by typing a keyword in the filter field, or click the button and select a keyword from a list. For example, to filter only sheets of a certain size, type a keyword in the filter box in the Sheet code column. Press the Enter key to filter.

Select Use default sheet when you want to use the default sheet size set for the material in the sheet library.

Set the Default Sheet

Gap

Determine the gap for the seams of the sheathing. Select either of the following:

• Default - By default, a gap is not set for the seams.
• Set - Enter the gap dimensions in the text fields:
  • Width - The gap in the shorter direction of the sheet.
  • Length - The gap in the longer direction of the sheet.

Flip

Select the sheathing angle in relation to the frame layer framing from the list. For example, select the tool Staggered:

Align

Select where to start sheathing in the X axis direction. For example, tool Staggered, Angle = 0, Layout direction = From bottom to top.

Left

Right

Middle - The center of the sheet is positioned to the center of the area.

Parts - The sheets are aligned according to frame parts.

Layout direction

Select where to start sheathing in the Y axis direction. For example, tool Staggered, Angle = 0, Align = Left.

From top to bottom

From bottom to top

Offset in sheet’s width and height directions

Enter an offset for the origin of the sheathing area in x and y axis directions of the sheathing area.

• Width: offset in the x axis direction of the sheathing area
• Height: offset in the y axis direction of the sheathing area

The location of the origin depends on the choices you make in Align and Layout direction. If the sheathing area has been divided into fields, all fields will have the same offset except in the following cases:

• the length of the sheathing area is smaller than the length of the sheet in that direction
• the field is a bracing area

Rules

Align sheet edges with the frame

When this feature is enabled, the program tries to align the seams of the sheathing to the frame parts. If necessary, the program resizes the sheet.

The minimum overlap with the piece

If the sheet overlaps the frame part at least for the minimum overlap, and the frame part also has space for the next sheet, the edge of this sheet will not be moved when aligning the sheets.

Adjust the widths so that last sheet's width is at least x mm

If the last sheet in the sheathing direction is narrower than this width, the program widens it by narrowing the previous sheet. If the width is less than the value in the Do not add a narrower sheet than field, the widths will not be changed but that sheet will be removed.
