Collaborate like never before

Conduct effective design reviews with lossless CAD data combined with reality visualization.
Just like meeting in person to review a physical prototype.


Save on travel time & costs through interactive & immersive 3D meetings. Select a 3D meeting environment, import 3D CAD content, invite others, interact & communicate – Just like a physical meeting.

Exxar has a Zoom-style easy-to-use workflow & replicates a physical meeting using following features that are not possible with Video conferencing solutions:

  • Individual viewpoints & Free navigation in the meeting environment
  • Real-time interactions with 3D content using built-in toolsets like X-ray, measurements, pick & move
  • 3D Annotations to provide specific instructions or highlights
  • Saving & loading sessions on the cloud for future meetings
  • Immersive Visualization using AR & VR

Digital transformation

Corporate Travel is expensive, time consuming & now restricted, due to COVID. Manufacturing Industry has been using physical equipment & travel for product design, training, sales & service activities. Exxar enables digital transformation of these processes by replacing a physical meeting with digital data, communications, interactions & environments.

With increased pressure for cost reduction, the pandemic has restricted the manufacturing industry in many ways. Now is the time for manufacturers & dealers to take the leap forward and enhance the customer buying experience through digitization.


Exxar Stream, our data ingestion engine, allows publishing existing CAD & Design content directly from your favourite 3D CAD application. Stream enables lossless CAD data integration without the need for manual content creation or data conversion steps. Stream integrates with all major CAD applications from Dassault (Catia, SOLIDWORKS), Autodesk (Navisworks), Siemens (SolidEdge & NX), PTC Creo & Aveva (Review, PDMS, Outfitting & Marine).


Traditional design tools use proprietary data formats requiring multiple manual conversions & optimizations. Stream makes this process as simple as a click of a button!

FAQ (Frequent Asked Questions)

Huddle allows you to join 3D Meetings from desktop PCs, mobile phones & tablets. You can also immerse yourselves in these meetings using VR/AR devices.
  • Supported VR headsets include the Oculus Quest, HTC Vive & Windows Mixed Reality headsets
  • Supported AR devices include ARcore-compatible Android mobile phones & tablets
The actual configuration depends on the following factors
  • Size & complexity of 3D models loaded inside Exxar
  • Use of Virtual Reality headsets
Huddle runs on Windows PCs with 4 GB main memory & built-in Intel graphics chips. However, for enjoying our high quality graphics with a smoother user experience, we recommend a minimal config of 8 GB memory with a discrete nVidia GPU. Your PC / workstation needs to be VR ready for it to be able to run with VR headsets
Yes!!! All user tools including annotations, X-ray, pick & move operations can be saved to the account as a Session.
No! Huddle only saves annotations on the server as Sessions. These can be loaded for future Huddle meetings. Exxar Stream is a one-way secure content publishing tool. We are careful not to touch or modify your CAD files directly. Stream works as a virtual driver with the CAD application to help you securely publish CAD content directly to If you need support for this feature, we will love to hear from you. Please give us feedback here & we might be able to get you a test installer faster than you think 🙂
Exxar pricing is not available on our web site! Checkout our Pricing page for more information. If you are an Enterprise user and want custom pricing for your specific requirements or if you want to avail special volume discounts, we will love to hear from you. Please contact us & our design consultants will get back to you as early as possible 🙂
No! Huddle requires the user to go through 2-levels of authentication to run:
  • Login to & authenticate against his/her account
  • Host or join a valid Huddle meeting (even if with only one user) to enable the 3D content stream & tools
If you need support for this feature, we will love to hear from you. We do engage with Enterprise clients on custom standalone builds for specific use cases where Internet access is not possible. Please give us feedback & we might be able to get you a test installer faster than you think 🙂

Why Real Time CAD Collaboration

Physical meetings are a costly affair, both in terms of travel time and cost. Global businesses spent over $1.33 Trillion last year on travel alone! The need for physical presence of individuals to communicate with each other is clearly expensive, not to mention the challenges in scheduling such meetings and repeating the same visits for follow-ups. But why are physical meetings necessary? For example, in the engineering industry, design reviews are incomplete without real scale visualization of product designs. Despite recent advancements in video conferencing technologies, sharing 3D content and experiencing it on a real world scale is not possible. Enter Real Time CAD Collaboration!!
