Introduction

Wood Framing Truss+ RT application for Autodesk® Revit®

1....allows users to generate roof and floor truss systems instantly, perform structural analysis and generate shop drawings,

2....allows user to draw custom truss design and use it in a project,

3....allows usage of steel trusses - user can choose either to use timber or steel truss framing,

4....lets you edit framing manually or automatically,

5....lets you design framing with thousands of possible configurations,

6....prepares shop drawings in just a few clicks,

7....optional CNC output enables your model data to be automatically exported for manufacturing,

8....saves vast amounts of time.

Wood Framing Truss+ RT makes wooden truss design fast and easy with real-time full project updates in Revit®. Plus it generates views with automatic dimensions and tagging for all truss elements. The tool prepares accurate bills of materials and shop drawings. Quality production and accurate assembly on site are ensured.

Recommended workflow

1. Build a model using Revit Roof functionality

2. Create roof types with layers → define roof thickness

3. Truss+ → Configs → Load Roof Truss Families / Load Floor Truss Families

4. Truss+ → Configs → Truss Database Manager → Modify and create new truss types

5. Truss+ → Configs → Roof Truss System Configuration → Modify and create truss systems

6. Truss+ → Configs → Roof Truss Design Settings → Modify truss type parameters

7.opt.1 Truss+ → Truss Systems → Insert Truss System Grid by one Roof Line →

→ Select the roof → Select one roof model line → Choose truss type

7.opt.2 Truss+ → Truss Systems → Insert Truss System Grid by Roof Lines →

→ Select the roof → Define roof lines by selecting model lines → Choose truss type

8. Select a Grid → Truss+ → Truss Systems → Insert Valley Set Grid

9.opt.1 Select a Grid → Truss+ → Truss Systems → Generate Trusses → Choose truss types

9.opt.2 Truss+ → Trusses → Insert Roof/Floor Truss by Selected Model Line → Select a model line drawn previously

1. Truss+ → Shop Drawings → Sort, Schedule, Tag and Dimension your trusses

2. Truss+ → Shop Drawings → Create Shop Drawings by creating an assembly

3. Truss+ → Shop Drawings → Export to CNC

Best practices for making roofs in Revit

Follow these simple steps to model a roof prior to using Truss+. The rules bellow will help you to establish correct connection of roof bottom face and wall top face.

• Use Roof by Footprint at the right level i.e. Wall Top Constraint Level

• Draw roof boundary lines by Pick Walls

• Go to roof element properties and select Truss in the ʻRa er or Trussʼ parameter

• Overhang must be extended to wall core

• Roof Base O set From Level must be equal to Heel Height minus Top Chord Depth/cos (Pitch) for raised heel trusses if top chord is attached to roof top face.

• Roof Base O set From Level must be equal to Heel Height for raised heel trussesif top chord is attached to roof bottom face.
