JetStream from NavisWorks is a complete design review solution for teams working with 3D models. It is modular in design, built around the core module Roamer with a set of powerful optional plug-ins: Publisher, Presenter, Clash Detective, TimeLiner, and RVM Reader.

Roamer is the central product of JetStream. It allows you to open multiple files from any of the major 3D CAD design formats into a single 3D environment. You can then navigate through the 3D model in real time and use Roamer's extensive toolset to review the design.

Key features:

• 3D File Support - Opens all major 3D design and laser scan file formats. (See the full list)
• Streaming - JetStream technology allows the handling of large models and intelligently streams content from disk or over the internet, enabling navigation around the design whilst the model is still loading.
• Merge Models - Models can be combined together, regardless of file format, into a single unified model.
• Real-time Walkthrough - Smooth real-time walkthrough with a range of navigation tools including:
  • Walk, Look Around, Zoom, Zoom Box, Pan, Orbit, Examine, Fly, and Turntable
• Gravity and Collision Detection - Gravity, collision detection and customizable 3rd person avatars, and allows navigation around the model without moving through walls.
• Review Tools - Review toolkit includes:
  • Measurements - Six tools to allow detailed measurement of distance, area and angle.
  • Viewpoints - Store, organize and share camera views of the design. These can also be exported into images or reports.
  • Comments - Add notes to viewpoints. Fully searchable including date stamped audit trail.
  • Redlines - Add mark-up to viewpoints using seven redline tools.
  • Section Planes - Add up to 6 cross sections to enable close inspection and focus on details.
  • Animations - Record animated walkthroughs for real-time playback or export as pre-recorded avi files.
• Reference Files - With our .nwf reference files every time the model is opened the latest version of the CAD design is used but past review data is kept. (Watch a demonstration of the JetStream workflow)-->
• Object Properties - Read intelligent data from the original design files and view it alongside the model.
• Database Link - DataTools feature allow import of live data from external databases using SQL through ODBC to be displayed with the model.
• SwitchBack - Open the current model and viewpoint in the original design software with one click. (Compatible with AutoCAD 2004 and up or Microstation J)
• Full Screen Mode - Run JetStream with the interface hidden or on a secondary screen.
• Collaboration - Multiple users can share a single review session through Windows NetMeeting technology.
• Stereo Viewing - Support for full OpenGL stereoscopic viewing. (Requires stereo capable graphics card and viewing hardware)
• API - Automate tasks or extend functionality using our extensive COM API.
• 3GB Support - Supports Windows XP running in 3GB memory mode, to load more of the model into memory at once.

Publisher allows you to publish your model in a single, secure and compact, .nwd file. This .nwd file can be shared freely with all stakeholders who can open it in JetStream or use Freedom our free viewer.

Key features:

• Publish to .nwd file - Store the complete 3D model in a single distributable JetStream model file.
• Free Viewer - Using Freedom nwd models can be opened freely by anyone.
• Internet and Office support - Our JetStream ActiveX control allows the viewing of an .nwd model from an internet page or inside a Microsoft Office document, such as a PowerPoint presentation.
• Compact File Size - Powerful compression can reduce the file over 70% versus the original design files.
• Security - Files can be password encrypted, time expired, made read-only, and have authorship and copyright details attached.
• Embedded Review Data - JetStream review data from Roamer, Clash Detective and TimeLiner is stored alongside the model.
• Embedded Materials - Presenter data including textures can be embedded inside the file.
• Embedded Properties - Object properties including external databases read through Roamer's DataTools can be embedded or excluded for added security.

Freedom is our free viewing software that can be downloaded and used by anyone to open .nwd files created by JetStream Publisher. It allows navigation around the model and viewing of embedded viewpoints, redlining and animations.

Key features:

• Completely Free - Anyone can download Freedom from our website and use it to open .nwd files.
• Navigation - Includes Roamer's full set of navigation tools.
• Review - Allows the viewing of review data embedded in the model, including viewpoint, redlines and animations.
• Materials & Lighting - Supports realtime display of materials and lighting added using the Presenter module.
• No Install - Available with or without an installer for users without installation privileges.

Presenter is a JetStream plugin that allows the enhancement of 3D designs with photorealistic materials and lighting. The results can then be exported into rendered images and animations.

Key features:

• Photoreal Images & Animations - Export realistic renderings into avi animations or static images.
• Drag & Drop Interface - Simple but powerful workflow. Most operations can be completed with a couple of drag & drops.
• Huge Archive - Over 1000 built-in materials.
• Full Customisation - Every aspect of the render, including materials, lights, backgrounds, and rendering styles, can be configured.
• RPC - Rich Photorealistic Content allows photographic imagery such as people and trees to be dropped into a scene.
• HDRI Lighting - Powerful rendering technology to provide smooth shadows and natural lighting.
• Environment Backgrounds - Photographic background scenery to add real world skies and landscapes.
• Realtime Shaders - Supports OpenGL 2.0 shader language to provide realtime lighting and shadows.
• Light Scattering - Create stunning night time imagery using our light scattering effect.
• Sketch Effects - Non-photorealistic rendering styles allow a variety of sketchy or painted effects.
• Real World Lighting - Support for real world lighting intensity units (Candela, Lumen, Lux, Foot-candle) and photometric lighting files (.cib, .cie, .ies, and .ldt).
• LWA-enabled - Presenter uses the LightWorks rendering engine, allowing you to add additional materials available from the LightWorks user site.
