Why is 3D
visualization and visual collaboration important
for manufacturers?
Visual collaboration
can make engineering teams more productive, resolve
design and manufacturing issues early, and improve
product innovation and quality. Visual collaboration
becomes more important every day as product design,
development, and manufacturing are globalized.
Manufacturers are
always striving to improve the value of the
organization, to improve products and the product
development process, and to reduce costs.
Companies invested in 3D digital design tools to
help them achieve some of these goals, and visual
collaboration has evolved naturally as a way to
extend that investment. Certainly, 3D design tools
play a major role in the hands of product
designers and analysts. Now, through 3D visual
collaboration, manufacturers can practice
knowledge reuse by distributing the information
resident in digital product models throughout the
company and the supply chain
What are
the biggest challenges in visual collaboration?
Manufacturing executives know that
global teams have to communicate well to stay
productive. But there are special obstacles to
collaboration involving 3D CAD, CAM, and CAE data:
-
Too many formats.Most
engineering organizations contend with multiple
authoring formats for 3D CAD, CAM, and CAE
product modeling. In large design projects with
dozens of suppliers, the diversity of authoring
formats can seriously hinder
communication.
-
Large data size.Product design and simulation models result in
very large files that must
be efficiently compressed before team members
can share them.
|

|
-
Uneven hardware
performance.Product development teams
typically collaborate withina heterogeneous hardware
environment. Some team members may not have
sufficient hardware
capability to handle large graphics files
easily.
-
Complexity.Nontechnical personnel do not have the
skills required to access necessary product
information where it resides in the native 3D
CAD, CAM, or CAE format.
Another important
challenge is finding a way to move beyond CAD
visualization. Compared to just a few years ago,
companies have become very practiced at sharing 3D
CAD models across the product lifecycle, but
visual collaboration in the 3D CAE and CAM areas
is still evolving. This is our area of expertise.
Our goal is to help engineering companies
communicate any product information, no matter how
complex, anywhere people need it.
The challenges of
visual collaboration originate in the unmet needs
of global product teams. They have been trying to
solve their collaboration problems with the tools
at hand, but it’s getting harder to do. To
collaborate with globally dispersed teams, CAE
managers often have to transfer huge analysis
models electronically, a slow, painful process
that chokes bandwidth and requires recipients to
have the same kind of CAE software on the other
end.
|
Consider the typical CAE design review. To
prepare for the meeting, the CAEmanager asks an analyst to capture
images that represent the simulation. The analyst captures some .jpeg files and some
.avi files, and the manager puts them in a PowerPoint
presentation. This is fine until somebody at
the design review asks a question about an aspect of the model
that isn’t depicted in the images. To cover this
contingency, the manager also has to bring the
analyst to the meeting, along with a UNIX box, since most CAE tools today
still run on UNIX boxes. So the analyst sits
there, and when a question comes up, they switch
to the UNIX box to show the specific CAE result
and answer the question.
|
 |
These are challenges
that occur every day in CAE visual collaboration.
Managers are either transferring huge chunks of
files back and forth or using .jpg and .avi files
to communicate. The big native file
transfers contain all the necessary information
for decision making, but they waste time and
network resources. The .jpg and .avi files are a
lightweight vehicle for collaboration, but they
don’t contain enough information.
What
background does your company have in this
market?
The company founders
and the key technical team have a great deal of
experience in implementing large engineering
visualization projects. We have been deeply
involved with high-end graphics and computing for
many years. We were originally formed in 2000
under the name VirtualE3D. Our vision was to
provide leading-edge engineering solutions in the
form of services and software products for the
science, engineering, and manufacturing
industries. We quickly began offering services in
CAD conversion, modeling, CAE analysis, design,
customization, translation, 3D Web viewing,
visualization, collaboration, e-manuals,
e-catalogues, digital mockups, virtual
prototyping, and product life cycle
management.
With broad-based
experience in providing all these services, it
didn’t take us very long to recognize that the
main bottleneck in CAD, CAM, and CAE effectiveness
and cross-discipline collaboration was the lack of
common communication format. Starting in 2001, we
began our own in-house R&D project to develop
a high-performance, common visual collaboration
platform for 3D CAD, CAM, and CAE technology. We
released the first version of the VCollab product
suite in 2002. In late 2004, we changed our name
to Visual Collaboration Technologies Inc. VCollab
2006 is the current version of the software.
Why does VCollab
stand out in the market for viewing technology?
VCollab is the most
multidisciplinary software for 3D product
visualization available today. With VCollab as a
common platform for 3D CAD, CAM, and CAE visual
collaboration, global product development teams
can share the most sophisticated information that
engineers create.
 |
This is very
significant, both for users of the software
and for corporate IT. Global product
development teams can use VCollab to visualize
and merge a wide variety of 3D CAD, CAM, and
CAE data sets into one common VCollab visual
file. The software then can integrate all of
that complex CAx data with Microsoft Office
tools and Internet Explorer for easy communication. This bridge between the complex
CAx world and MS Office applications
makes possible a whole range of new productive
applications for our end customers. Imagine
teams using MS Office to open a CAE
simulation. A single PowerPoint slide, for
example, can combine a view of 3D CAD product
geometry with separate windows for viewing a
manufacturing simulation and manipulating CAE
analysis results. VCollab is the only
technology that can do this with manageable
file sizes. |
The software is
especially capable of handling large data sets. It
delivers high-performance visualization on laptops
and desktops.
VCollab appeals to
corporate IT departments for two reasons. First,
the software features a professional viewer, which
we support. Many CAx authoring tools come with
free viewers that the vendor does not support, so
corporate IT spends a lot of time troubleshooting
viewer problems for users. Second, we offer a
common viewing platform for 3D CAD, CAM, and CAE
data, which is a plus for IT departments that wish
to consolidate technology. We are continually
building and investing in VCollab as a neutral
visual collaboration platform, working closely
with CAx vendors , PLM vendors, and hardware
vendors to deliver true value to our end
customers.
VCollab addresses the
pain points in visual collaboration in a way no
other software does. CAD, CAM, and CAE files are
very large. For long time, everyone thought that
bigger computers with more RAM and better graphics
cards would be the key to solving the problem of
handling these large files. But the bigger the
computers become, the bigger the engineering
problems become. VCollab doesn’t challenge a
company’s current hardware platform. The
software provides a framework that can help users
control file sizes and frame rates. For example,
they can pick a portion of the geometry or
analysis results from a large file and then apply
compression and culling techniques. The final
compressed file size might be anywhere from 5
percent to 30 percent of the original size,
depending on the selections made. VCollab files
can then be embedded in presentations and
documentation, utilized for version control
purposes, or simply stored for further use.
Perhaps most important,
VCollab is unique in its intention to encourage
interdisciplinary communication in product
development. CAD engineers, CAM engineers, and CAE
engineers all use complex authoring tools. They
are not literate in each other’s software, but
VCollab gives them and their managers a common
platform for communication and for understanding
3D CAD, CAM, and CAE data in context as a product
evolves. The more global teams and suppliers a
company has, the more they appreciate the
collaboration speed and ease of use that VCollab
offers.
What are
the different tools in the VCollab software suite?
VCollab Pro is
a high-performance, scalable visualization tool
that converts 3D digital product data into one
viewing format. The software takes a CAD file
output as VRML and converts it to a .vcb file. It
also converts CAE and CAM files to .vcb format,
using a special utility called VMove CAE.
 |
These .vcb files from
CAD, CAM, and CAE sources can then be combined in
different ways for extensive digital mockup and
virtual reality applications such as animations
and walk-throughs, assembly sequences, view and
markup, dynamic sectioning, and 3D immersive
stereo viewing. VCollab Pro is a powerful tool in
the hands of specialists who are called on to
provide diverse product imagery for collaborative
decision making.
VCollab Presenter
is an easy-to-use viewer for exploring 3D files
that have been created with VCollab Pro. The
viewer displays VCollab files using Internet
Explorer, and it opens VCollab files that have
been embedded into Microsoft® Word, Excel, and
PowerPoint. Anyone can use VCollab Presenter to
view and manipulate 3D CAD, CAM, and CAE
simulations and product models.
|
Used together with
Microsoft Office, the VCollab suite connects
complex CAx tools with business applications that
most people already know how to use. VCollab
offers a remarkably easy way to distribute complex
3D CAD, CAM, and CAE product information
throughout the enterprise for presentation,
visualization, documentation, and collaboration.
Dramatic improvement in the innovation and
productivity of global product teams is a sure
result.
What
software or software category does VCollab compete
with?
Like any new
technology, VCollab crosses traditional software
categories. It is similar to some tools that have
been included in the digital mockup,
visualization, and publishing (DMV) market, but
most of these products are very CAD-centric.
VCollab is not limited to CAD visualization. It
bridges all the engineering disciplines. Thanks to
the neutral flavor of its platform, VCollab can
focus on all aspects of the product, including its
performance. No other visualization software is
able to do so much
What is
the difference between post-processing software
and VCollab?
VCollab comes after CAE
post-processing and complements post-processing.
Post-processing is for expert analysts, whereas
visualization is for everyone. VCollab gives
companies a way to maximize the utilization of
post-processed results beyond the specialists. It
adds a great deal of value to the virtual product
models that specialists create. For example,
engineering teams can combine CAE data with CAD
and CAM data for a view of the digital product
model that is richer and far more integrated than
what a post-processor can offer. And they can do
this in very small files for distribution beyond
engineering.
Describe some
VCollab implementations.
Our customers
communicate 3D product data within their
organizations and with upstream OEMs and
downstream suppliers. Some are using VCollab to
bring submodels from different CAM packages
together. Others are comparing styling data with
CAD geometry, or viewing CAE meshes together
with CAD geometry. One customer is exploring the
benefits of VCollab for combining, into a single
view, results from transient aerodynamics
simulations and structural dynamics of an
aircraft. Another is using the software to
visualize large engine and transmission simulation
results. We had one customer use VCollab to
archive automobile crash simulation results and
then share those results with overseas colleagues
and outside contractors. A number of customers are
using VCollab to integrate all modeling and
simulation data into a virtual prototype, which
they then visualize in stereo in large VR centers
for product demonstrations, design reviews,
decision making, and global training. VCollab has
also been used to publish an e-document of a user
manual and for real-time review of engineering
data.
In small companies,
VCollab users can simply download the software,
install it, and begin to create 3D visualizations.
In larger companies, VCollab is typically
implemented alongside a PDM or PLM system or a web
archiving/accessing system.
How is VCollab
being sold?
The VCollab suite of
software is available according to various
licensing mechanisms, depending on customer needs:
annual, perpetual with maintenance, node lock,
floating, and so on. For large corporations,
we provide customized volume licensing schemes.
Facility to write to .vcb format is provided free
to vendors of CAD, CAM, and CAE software.
