Navisworks File Formats

9

• NWF: contains an index of all model files you are using, also stores all other

NavisWorks data. For example, a DGN, viewpoints and redlining and etc.

• NWD: stores all of the NavisWorks specific data that the NWF file format

stores, as well as the geometry of the model.

• NWC: contains a cached version of the converted model geometry, is

not intended for general use

Which version of Navisworks is better for saving our files?

Real-Time Navigation

Explore your integrated project

model using advanced navigation

tools that produce a realistic, real-

time experience.

Real-time navigation capabilities are

included in all Autodesk Navisworks

products.

Project Viewing

12

Whole-team Project View

Provide equal access to explore the whole

project view.

In Autodesk Navisworks you can open files

originated from a variety of CAD

applications. You can combine these files

together, and create a single Autodesk

Navisworks file with a whole-project view of

your model. This file brings together

geometry and data created by multi-

disciplinary teams, and enables you to

explore and review complex models in real-

time.

Project Review Features

13

Model File and Data Aggregation

Autodesk Navisworks can be used to combine multiple models (civil, architecture,

MEP, Structure) of a building into a single 3D model that can be used for

visualization, clash detection or virtual inspection.

Home >>> Project


14

Review Toolkit

The software’s review toolkit offers a host of tools that

facilitate whole-project review. Its features enable you

to measure distance, areas, and angles; store,

organize, and share camera views of a design and

export those views into images or reports; and add

cross sections and section plans to inspect details

closely.

Review >>> Measure

Navisworks NWF reference files enable you to view the latest version of a CAD

design while maintaining previous review data.Viewpoint >>> Enable Sectioning


15

NWD and DWF Publishing

Publish your entire project for a whole

project view. Complete project models

can be published and stored in a single

distributable NWD or DWF file with

compressed file sizes up to 90 percent

smaller than original design files.


16

Collaboration Toolkit

Communicate design intent and encourage teamwork with the ability to add

markups to viewpoints with advanced redlining tools, comment on viewpoints with

searchable notes, record animated walk-throughs for real-time playback, and

stream large models and content, navigating the design as the model loads.

Review >>> Redline Review >>> Comments


17

Simulation and Analysis Features

18

Photorealistic Model Rendering

Use Autodesk Navisworks advanced visualization features to develop compelling

3D animations and imagery to present projects to stakeholders. Customize and

configure every render aspect, including materials, lights, backgrounds, and

rendering styles; use environment backgrounds to add real-world scenery; and

choose from more than 1,000 built-in materials to create an accurate, photorealistic

look. Render >>> System

19

Object Animation

The software’s object animation features help you create animations of objects for

clash and interference analysis. You can create interaction scripts that link

animations to specific events, triggers, or key comments, and link animations to

tasks in a 4D schedule for improved construction planning.

Animation


20

Simulates construction schedules and logistics in 4D to visually communicate and

analyze project activities, and help reduce delays and sequencing problems. The

4D scheduling features enable you to verify building or demolition viability by

4D Product Scheduling


developing construction or demolition

sequences that link model geometry to

times and dates; import times, dates, and

other task data from project management

software to dynamically link schedules with

project models; and set up planned and

actual times to visualize deviations from the

project schedule.

Coordination

23

BIM Coordination with AutoCAD 2017

Open Navisworks files within AutoCAD, Revit, and ReCap.

BIM 360 Glue Integration

With the BIM 360 add-in for Autodesk Navisworks, you can share the latest project

models directly to your BIM 360 project from within Navisworks.

To coordinate Navisworks models with other models in BIM 360 Glue, you must

use the Navisworks add-in and use the Glue feature to share Navisworks models

to the BIM 360 cloud.BIM 360

Clash Detection and Interference Checking

24

Anticipate and avoid potential problems

before construction, reducing expensive

delays and rework. Clash and

interference detection features in

Autodesk Navisworks Manage software

enable you to perform clash tests

against specified geometry to more

easily find and resolve conflicts. Link

clash tests to 4D simulations and object

animations to analyze issues in space

and time.

25

Home >>> Tools >>> Clash Detection

Autodesk Navisworks Manage software provides the ability to manage and track

clashes and interferences through to resolution. Reports of clash tests, including

comments and screenshots, can be exported to communicate issues to the project

team.


26


Quantity Takeoff

27

5D Simulation (Integrated Model Takeoff)

Quantification is a core piece of functionality of Navisworks. Using a 3D model, you

can create a highly accurate quantity takeoff that ties it physically to the model.

Project Specification

31

Architectural Model Name: rac_basic_sample_project

Default Path: C:\Program Files\Autodesk\Revit 2020\Samples

Structural Model Name: rst_basic_sample_project

To review the mentioned features of Navisworks, we use the sample Revit files (a

house) generated by Autodesk:

rac_basic_sample_project.rvt

rst_basic_sample_project.rvt

Initial model set up and project review

32

• Export NWC file from Revit.

• Open NWC file in Navisworks.

• Save as NWF file with the same name and in the same location as NWC file.

• Create some search sets.

• Work with Viewpoint tab functions and navigate in the model.

• Work with Review tab functions.

• Explore in project and make some animations.

Hands on software (Autodesk Navisworks Manage)

Simulation, 4D modeling and Quantity take off

33

• Explore in project and make some animations.

• Work with timeliner, create some tasks and link model geometry to times and

dates.

• Run the quantity take off.

Clash detection

34

• While the architectural model is opened in Navisworks, append the structural

model.

• Run the clash detection.

Navisworks Features

• Export the RVT architectural model to NWC and open it in Naisworks

• Create a simple animation (about 5 sec.) (in this step, save as NWF file and send the NWC

and NWF files to the TA)

• Append the structural model (NWC File)

• Create some search sets

• Work with timeliner, create some tasks (or add a data source (MSP file)) and link model

geometry to defined tasks using the search sets and create the 4d model and export it as

an AVI file) (send the NWC, NWF and AVI files to the TA)

• Run the clash detection between architectural and structural model and export a HTML

Tabular report. (send the NWC, NWF and HTML files to the TA)

• For quantification, create WBS of the project using search sets and run the quantity take off

and export quantities to Excel. (send the NWC, NWF and Excel files to the TA)
