more quickly and accurately with Autodesk Raytracer

rendering engine.

You can specify many different graphic styles for a

project view. Visual styles are grouped into model

display, shadows, lighting, photographic exposure, and

background options.


View >> Presentation

12

Cloud rendering

Produce photorealistic visualizations without tying up your desktop or using special

rendering hardware.


View >> Presentation

13

Point cloud tools

Connect laser scans directly to the BIM process to author an as-built model.

Link a Point Cloud file into the project to provide a highly accurate visual reference

of the existing condition of a building or site.

This reference can then be used to assist in your building information modeling

(BIM) authoring tasks.

Insert >> Link >> Point Cloud

15

Structural modeling

Add structural elements to the building model:

• Beams

• Walls

• Columns

• Floors

• Trusses

• Braces

• Beam Systems

• Foundations

Structure


16

Structural steel modeling

Model connections with a higher level of detail using a

variety of parametric steel connections in Revit or by

creating your own custom steel connections.

17

Reinforcement detailing

Create 3D reinforcement designs for cast-in-place and precast concrete structures.

Produce reinforcement shop drawing documentation with rebar schedules.

Structure >>> Reinforcement


18

Structural documentation

Create more accurate, detailed documentation of steel and concrete designs. Model

elements are direct presentations of information from the building database.


Physical and analytical model

Create a physical model for coordination and documentation,

and an associated analytical model for structural analysis.

Revit develops automatically while you develop the physical

building model.

19

An analytical model is a simplified 3D representation of the full

engineering description of a structural physical model. The

analytical model consists of those structural components,

geometry, material properties, and loads, that together form an

engineering system.

Physical Model

Analytical Model

• Structural Columns

• Structural Framing elements

(such as beams and braces)

• Structural Floors

• Structural Walls

• Structural Foundation

elements

The following structural elements have structural member

analytical models:

Analyze >>> Analytical Model


20

Bidirectional linking with analysis

Integrate analysis results into the BIM process and work in an iterative design

workflow.

Analyze >>> Structural Analysis >>>

Robot Structural Analysis

Use it to perform advanced analyses after transferring a Revit analytical model to

Autodesk® Robot™ Structural Analysis Professional (Robot). It is a structural

analysis and design software application. Use it to perform linear and nonlinear

analyses of any structure type and shape and to design steel, concrete, and timber

elements of a structure.


21

Linking with structural fabrication

Interoperability between Revit and

Advance Steel helps provide a seamless

BIM workflow from steel design to

fabrication.

The Advance Steel Extension for Revit

allows you to exchange BIM data from

your models between Autodesk Revit and

Autodesk Advance Steel. You can export,

import and synchronize BIM data from

your Autodesk Revit models for structural

analysis and detailing in Autodesk

Advance Steel.

Add-Ins >>> Advance Steel Extension

HVAC design and documentation

Design complex duct and pipe systems to express intent, and model duct and pipe

systems with mechanical design content.

System >> HVAC

24

Electrical design and documentation

Design, model, and document electrical systems. Keep track of electrical loads

throughout the distribution system.

Create electrical systems

(circuits) to place devices,

lighting fixtures, and electrical

equipment in a project.

System >> Electrical


25

Plumbing design and documentation

Create sanitary plumbing systems with sloped piping and layout piping systems to

design and document intent.

System >> Plumbing & Piping


26

Insight integration

Insight lets you optimize building performance with centralized access to

performance data and advanced analysis engines.


Analyze >>> Insight 360

27


Construction

28

Construction modeling

Derive construction insight from design models. Split and manipulate wall layers

and concrete pours, and prepare shop drawings for fabrication.

Divide elements into parts or combine them into assemblies as needed to support

your construction modeling workflows.

Two Revit categories are designed to support

construction modeling workflows:

• Parts

Divide building model elements into discrete parts that

can be independently scheduled, tagged, filtered, and

exported.

• Assemblies

Combine multiple building elements into a single

assembly that can be independently scheduled,

tagged, and filtered. Place instances and quickly

generate assembly views.

Modify >> Create

29

Construction coordination

Upload Revit models into BIM 360 Glue and sync with

BIM 360 Layout. View and share point sets in the BIM 360

Glue web interface or the BIM 360 Layout iPad app.

The BIM 360 add-in app for Autodesk Revit supports

round-trip BIM coordination workflows between Revit and

the BIM 360 Glue cloud.

Add-Ins >> BIM 360

Construction

Centralize BIM Models

Merge models in the

cloud to collaborate and

coordinate with project

stakeholders.

Round Trip Coordination

Desktop to cloud model

merging, versioning and

clash resolution.

Extend Model Access

Provide access to 50+

file formats to workers in

the field on their iPads

30

Navisworks interoperability

Use interoperability workflows between Revit and

Navisworks to see your design in the context of

other models and to check for conflicts.

NWC Export Utility

You can use a utility to export Revit models for use

in Navisworks. Install the utility as a stand-alone

exporter, or install it during

the Navisworks installation.

Parametric components

Parametric modeling refers to the relationships among all elements in a project that

enable the coordination and change management that Revit provides. These

relationships are created either automatically by the software or by you as you work.

34

Worksharing

Contributors from multiple disciplines can share and save their work to the same

centrally shared file.

Collaborate >> Manage Collaboration

More Features

35

Schedules

File >>> Export >> Reports >>> Schedule

37

Interoperability and IFC

Revit imports, exports, and links your data with

commonly used formats, including IFC4.

IFC uses architecturally meaningful containers

to describe real-world building objects. Those

containers include parameters that have

meaningful values. Many standard Revit

elements have corresponding IFC containers.

These do not require any specific user action

to export them. (For example, Revit walls

export as ifcWalls.)

File >>> Export >>> IFC

38

Add-ins

Extend Revit functionality with API access, add-ins,

and a content library on the Autodesk App Store.

More Features

The followings are general areas where the API is suitable:

• Creating add-ins and macros to automate repetitive tasks in the Autodesk Revit

user interface

• Enforcing project design standards by checking for errors automatically

• Extracting project data for analysis and to generate reports

• Importing external data to create new elements or parameter values

• Integrating other applications, including analysis applications, into Autodesk Revit

products

• Creating Autodesk Revit project documentation automatically

39

Annotation

Communicate designs more effectively

with WYSIWYG editing and features

that let you control text appearance.

Annotate

More Features

40

Dynamo for Revit

Expand and optimize BIM workflows with an open-source graphical programming

interface that installs with Revit and use computational logic to develop optimized

systems.

Manage >>

Visual Programming >>> Dynamo

More Features

The visual programming interface of Dynamo is enabling engineers with the tools to

build optimized structures with minimal energy, and subsequently make their own

design tools. Based on the Revit Platform, we can use our creativity to develop

optimized structural systems using computational logic in an advanced building

information modeling environment.

41

Global parameters

A global parameter is a project-wide parameter that you create inside a project and

can be used to assign or report a value across the entire project.

More Features

Global parameters are specific to a single project file, but are not assigned to

categories like project parameters. Global parameters can be simple values, values

derived from equations, or values taken from the model using other global

parameters.
