Overview of Solid and Surface Modeling tools in Revit

© 2012 Autodesk

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

© 2012 Autodesk

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
