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

Solid Modeling Tools for Families

Create solid shapes that represent the overall form of the family

Five types of forms can be created
Solid Extrusion
Solid Blend
Solid Revolve
Solid Sweep
Solid 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
Void Extrusion
Void Blend
Void
Revolve
Void
Sweep
Void Swept
Blend

Learning Objectives:
1. Working in the Family

2. ‘Structural Framing’
Template
3. Solid & Void Extrusion

Which Structural Framing Template?
1. Structural Framing Beams &
Braces.rft
2. Structural Framing Complex &
Trusses.rft

Structural Framing Template: Beams & Braces
1.
Built-in-Reference PlanesWhat they mean? & What
they do?
2.
Material for Model Behavior
3.
Symbolic Representation

Reference Planes in the Structural Framing: Beams &
Braces
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"
© 2012 Autodesk
‘Symbolic Representation’ in the Structural Framing
Template
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

‘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

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

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’

Concrete Tilt up Panels
• Create Concrete wall and use
‘split with gap’ tool
• Use the PARTS tool
