Overview of Solid and Surface Modeling tools in Revit

Revit families are groups of elements of the same type. All theelements in a family have a common set of parameters,identical uses, and similar graphical representations.
System Component
Revit Families
•Beams
•Braces
•Columns
•Stiffeners
are created and edited solely within a project and depends on that project model.
•Walls
•Floors
•Roofs
•Ceilings

Solid Modeling Tools for Families Create solid shapes that represent the overall form of the family
Five types of forms can be created
Solid Blend Solid Revolve Solid Sweep Solid Swept Blend
Solid Extrusion
© 2012 Autodesk
Void Extrusion Void Blend
Void Revolve
Void Sweep
Void Swept Blend
Void Tools for Families Create subtractive solid shapes that form a void in the solid mass by subtracting
material away from the solid Five types of void forms can be created

Modeling a Precast Concrete Beam Slab/Void Slab Component
Learning Objectives:
1. Working in the Family Editor
2. ‘Structural Framing’ Template
3. Solid & Void Extrusion
© 2012 Autodesk
Which Structural Framing Template?
1. Structural Framing Beams & Braces.rft
2. Structural Framing Complex & Trusses.rft
© 2012 Autodesk
© 2012 Autodesk
Structural Framing Template: Beams & Braces
1. Built-in-Reference Planes-What they mean? & What they do?
2. Material for Model Behavior
3. Symbolic Representation
© 2012 Autodesk
Reference Planes:Left/Right: Full Extent of the geometry, Controls the length of Framing
Member Left/Member Right: Physical Geometry Edge/Cut back, Controls Cut Length
Stick Symbol Left/Right: Extents of stick representation when symbolic representation is set to "From Family"
Reference Planes in the Structural Framing: Beams & Braces
© 2012 Autodesk
Symbolic Representation:
From Family: Stick Symbol is not auto created/auto generated
From Project Settings: Revit generates the stick symbol and follows the project ‘symbolic cut back’ settings under Manage>Structural Settings
‘Symbolic Representation’ in the Structural Framing Template

‘Material for Model Behavior’ in Structural Framing Template: Beams & Braces
Controls the Joining behavior of these members in a project, Example: Concrete beams auto join whereas Precast Concrete beams do not

Warped Double Tee
Learning Objectives:
1. Understanding and working with Family Profiles
2. Nesting Families
3. Using the ‘Swept Blend’ Geometry Creation tool

Thin Shell Concrete Roof (Hyperbolic Paraboloid)
Learning Objectives:
1. Working in the Massing Family Template
2. Using the Massing tools
3. Create ‘Roof’ by Face

Modeling Rebar
Two Primary Methods:
1. Place/Model Reinforcement using Reinforcement tools in Revit2. OR use Extensions (download from Subscription Center)
© 2012 Autodesk
Custom Rebar Shape
Learning Objectives:
1. Working in the Reinforcement family Template
2. Create Custom Rebar Shape
3. Create parameter labels to control the rebar dimensions

Tips & Tricks
• Understanding Join Geometry in Revit Structure Joins & vs./ attachment Graphic appearance of joined vs. non joined concrete elements Joining Multiple items at once
• Pre cast Tilt up Panels (Using Parts)• Flat Slab with Sloped Soffit• Thickened Slab Edges

Joining Multiple Components

Concrete Expansion Joints
•Use Opening by face (time consuming)
• Create a face based/line based void family
• Change the ‘Material for Model behavior in the family template to ‘Precast Concrete or Other’
© 2012 Autodesk
Concrete Tilt up Panels
• Create Concrete wall and use ‘split with gap’ tool
• Use the PARTS tool
