Usage of Navigation tool , Timeliner and Clash Detection test using Naviswork

1. Aim : Export the revit architecture and structure model to Navisworks Cache.

• Open the Revit file (Architecture or Structure).
• Go to a 3D view actually want in the export
• Head to the “Add-Ins” tab, then choose:
• i. External Tools → Navisworks Exporter
• Check the export settings:
• i. Element Properties: On
• ii. Linked Files: On
• iii. Coordinates: Use Shared
• iv. Room Geometry: On (for Architecture)
• v. Construction Parts: Off
• Export it as a .nwc file
• Save it in project folder (maybe a folder called “Navisworks Exports”)
• Name it clearly, like:
• i. Architecture.nwc
• ii. Structure.nwc

2. Aim : To use navigation tool to walk around the model and walk through the rooms created

a. Use Walk Tool

Go to Viewpoint tab → Navigation Modes → Walk.

right-click and drag to look around.

Turn on Gravity and Collision Detection for realism.

b. Record Walkthrough

Go to Viewpoint tab → Record Animation.

Walk through the model — it records as we move.

Click Stop when done.

c. Save & Export

Go to Saved Viewpoints panel → find the animation.

Right-click to rename.

Export: Output tab → Export Scene → Animation (AVI/WMV).

3. Aim : To use Navigate tool to use Realism feature to walk through the model and record moving as animation in Navisworks file

a) Open the Model
Load the NWD/NWF/NWC file in Navisworks.

b) Enable Realism
Go to the Viewpoint tab → switch to Walk Mode → turn on Gravity and Collision Detection for a realistic feel.

c) Do the Walkthrough
Use mouse to explore the model. Walk through like giving a tour.

d) Record It

a. Option 1: Save key viewpoints (F2), then animate between them in Animator.

b. Option 2: Open Animator, hit Record, walk through — done.

e) Export Animation
Go to Output > Export Animation → choose video format (AVI/WMV) → set quality → export

4. Aim To create a clash detection test between the two models

a) Bring in The Models

· Open Navisworks and append both the architecture and structure .nwc files.

· Make sure they’re aligned and sitting nicely together.

b) Set Up the Clash Test

· Go to the Clash Detective tool.

· Create a new test – name it something like “Arch vs Structure”.

· Pick architecture for Set A, and structure for Set B.

· Use “Hard” clashes, then hit Run Test.

c) Look Through the Clashes

Go through each clash and decide:

· Approve – if it’s intentional or within tolerance.

· Ignore for now – if it’s something minor that’ll be fixed later on-site.

· Needs fixing – if two elements shouldn’t be overlapping at all.

d) Color Code and Comment

· Mark them:

o Green = Approved

o Yellow = Deal with later

o Red = Needs fixing

· Drop quick comments so the team knows why it’s marked that way.

e) Save The Progress

· Save the Navisworks file so the test and results are kept.

· We can also export a report if needed.

f) Annotate and Save Views

· For clashes that need fixing, use the Redline tool to mark them up.

· Then save a viewpoint with a clear name.

5. To prepare a schedule for the project developed by adding reasonable assumptions for task start date and end date and simulate the task completion as a visual simulation.

a) Open the model

Open Navisworks and open the model worked on .nwd or .nwf file.

b) Open the Timeliner tool

c) Make up a simple schedule

For example:

Task	Start	End	Just a note
Site prep	May 1	May 3	Clearing, leveling
Foundation	May 4	May 10	Pouring concrete
Framing	May 11	May 17	Walls, structure
Roof	May 18	May 21	Slap the roof on
Plumbing & Electrical	May 22	May 27	Rough-ins
Interior Finishes	May 28	June 3	Painting, flooring

d) Match tasks to parts of the model

· Click on one of the tasks.

· Attach.

· Then go into the model view and select the objects it relates to.

· Repeat for each task.

e) Go over to the Simulate tab in Timeliner.

· We can slow it down, speed it up, or make completed items change color.

f) Make animation

· Click Export Animation.

· Choose a video format (AVI is fine).

· Export it, and timeline simulation video.

g) Save everything

· Go to File > Save As.

· Save it as an .nwd file so it includes the simulation and all the linked stuff.
