Simplified Decking for Roofs

SAPPHIREâ„¢ Structure provides a simplified method of optimizing decking layouts for roof systems and displays the layout and visibility of decking on roof planes and the number of sheets. Designers have the ability to specify a layout start point. All sheathing panels will emanate from that orientation point

The settings for roof sheathing exists in the properties of the roof plane. SAPPHIRE Structure draws the outlines for the sheathing material such that the plane is properly covered for a completed output.

SAPPHIRE Structure automatically creates a decking layout for roof planes if sheathing is selected and roof planes are cut. The program accounts for the slope of roof plane when displaying roof decking objects in plan view and will regenerate the roof decking layout if the slope of the target plane is adjusted.

There are two ways to turn on the properties for roof decking.

One is turn on the Specify Material setting when using the Input Plane dialog. Select the Advanced tab, then select the checkbox for Specify Material.

The other method to create and place rood sheathing is in the Property Grid for Planes. In this Property Grid, the designer can select to Specify Material. Once selected, the sheathing type and material can be selected. Use Decking Orientation to control whether decking is placed perpendicular (default setting) or parallel.


The Decking Row Offset setting controls the distance to offset the start of successive row when decking is placed.

Once the roof planes are cut, the sheathing is displayed in Plan View by selecting the visibility switch for Roof Material.

Visibility Switches

SAPPHIRE Structure uses the current visibility switches to control the visibility of the roof decking and labels for the roof decking.  Located under Objects>Planes>Roof Material, the default setting is OFF for this visibility switch.

When Roof Material is selected and turned ON (), the roof decking objects in Plan View are displayed using the actual material size.

SAPPHIRE Structure provides visibility switch for roof material labels beneath Labels>Roof Framing named Roof Material.

In 3D view, the Visibility Switch is located under Objects>Planes>Roof Material; the default setting is OFF for this visibility switch.




SAPPHIRE Structure attempts to place the label at the center of each piece of decking for floors.

For roof decking, SAPPHIRE Structure labels the decking pieces beginning at the first sheet created within the perimeter of the plane decking container, closest to the Layout Start Point.

For roof decking, the system shall label the sheets within an entire row, move to the row above, label those sheets, beginning with the left-most sheet in that row, moving right, until all sheets are labeled.

For roof decking, after the first plane's decking has been completely labeled, the system shall select the next plane to label decking

Consolidate Labels

1. Select the Labeling icon from the main toolbar.


2. Select the Consolidate icon to consolidate the roof decking labels.

3. Roof decking labels are consolidated; all roof sheathing sheets have a label of R1.

SAPPHIRE Structure reports floor decking in the Accessories section of Layout Materials List. Plot ID's and Length are ignored. SAPPHIRE Structure reports the number of full sheets, consolidates partial sheets into equivalent full sheets, and reports number of full sheets.

To Create  A Layout Material List, complete the following:

1. Select Text and Annotation icon from the main toolbar.

2. Select Create Material List icon.

3. Place the Accessories layout material list.

Waste Factor Setting

SAPPHIRE Structure respects the Waste Factor Inclusion settings for floor decking at Job Properties/Job Settings/Output/Material Length Rounding.



Output>Material List

SAPPHIRE Structure reports roof decking on Output: Materials List. Select Output, the Print My Reports.

The Material List Report is then generated. Roof decking is placed under Accessories and displayed as shown below.


Adjust Roof Decking Layout

The designer is able to modify the orientation start point, indicating the origination for the sheathing within that floor container. All sheathing panels will then emanate from that orientation point.

To adjust or modify the floor decking point, complete the following steps:

1. From Planes toolbar, select the Adjust Floor Decking Layout tool.

2. The status bar prompts to select a plane to adjust Layout Start point.

3. Upon selecting the plane, the existing Layout Start Point is displayed in plan view with a red "X".


4. Select the new Layout Start Point.


5. Roof decking placement is modified according to the new Layout Start Point. With a new Layout Start Line, a new Layout Start Point is generated based on the rules of system-generated roof decking.
