ISE in action [Webinar]”

The process begins by either leveraging the included Civil Engineering Catalogues (i.e. smart tools, reusable components, and IFC-compliant objects which speed up the creation of the skeleton), or the design can start from scratch.

In our railway/bridge project example, the user creates a site from scratch, inserts the terrain, and imports a point cloud to set up the canvas for the structure. The railway’s center curve, imported from a IGES, STEP, or IFC format, is geo-located onto the map.

The Terrain Preparation app allows the user to create a mesh on the point cloud, and apply a contour map to reveal the elevation curves.

You’ll also see how to geo-locate objects by using coordinates from Google Maps, in order to insert 3D mockups of local landmarks, analyze the project’s environmental impact, run noise simulations, and more.

A Large Range Scale is available to mix large range objects with normal range objects within the same view.

Civil Design automatically generates excavation along the center curve, driven a by parametric trapezoidal profile, and estimates the volume removed from the terrain mesh.

The user can modify the side angles and base width as needed. This allows the engineer to compute the excavated volume and get an early estimate of cost and duration.

The project in our demonstration incorporates a constant deck and a cantilever. You’ll see how the engineer creates each using a combination of templated objects and custom modifications.

To make multiple design options, the engineer quickly creates alternatives by selecting the piers and applying a different template.

The edited elements are color-coded to highlight the difference between versions.

All About the 3D Dream Sketcher

By David N.
Share on LinkedInTweet about this on TwitterShare on FacebookShare on Google+

The 3D Dream Sketcher is an experience produced by Dassault Systèmes (3DS) with two main objectives:

– Increase online traffic and booth attendance during an event (such as the CES 2016),

– Crowdsource the value of an immersive ideation design tool targeting the general public as well as professional creative designers.

How Does It Work?

Users are asked to think of themselves in an imagined role, and then sketch it in the air. At the beginning of the experience, users are scanned by a pair of kinects so as to create an engaging starting point: their body!
The user sketches for 3.5 minutes while looking through a VR headset and using two hand-held controllers, as the public watches the scene through an external screen.
A 360° bullet-time animated gif is generated and uploaded onto the cloud, and an email containing a link to the gif is sent to the user.
The user can then give it a title, opt to make it public and share it through mail or on most social media.

Here is how it looked when embedded in Dassault Systemes’ website event page for CES 2016:

The Origins

The experience leverages the recently released HTC Vive Pre VR Headset and controllers along with earlier 3DS projects.
The first project, “Never Blind in VR”, explores how one relates to an immersive live representation of one’s own body. This actually showcased last year at the Laval Virtual Revolution competition.
The second, “BikePics”, examines the impact of augmented selfies shared on social networks. To have a deeper on this 3DXPERIENCE, you can either watch its video of go through this twitter wall.

Marketing Results

The 3D Dream Sketcher welcomed 220 users during the four days of the CES 2016, with impressive results in terms of traffic:

Firstly, it consistently drew throngs of visitors to the booth, proving that VR is a crowd-pleaser that helps brands to engage with captivated audiences.

The experience also contributed to significantly increasing the number of followers of 3DS digital channels on social media (sorry, but we can’t reveal the actual figure), with around 1,000,000 impressions, mostly through Facebook, LinkedIn, Instagram and Twitter.

Outcome for a New Design Solution

This experience has shown us that using a user’s body scan is a good way to circumvent the “blank page syndrome”, while giving the user a better sense of scale and proportion. This is of particular interest for more “serious” applications where sketches are transformed into products or services.

We also received very interesting feedback on how sketching directly in 3D is of particular interest to users who find pen and paper drawing a challenge (it’s so much easier than drawing on paper)

In addition, “social media curation” worked extremely well: having the outcome of the experience sent to a social platform where in two clicks participants could share noteworthy results on social networks. In terms of product ideation research, this may present significant value.

Finally, the experience has shown to be of interest and potentially useful to professional creative designers.

The project is conducted under the 3DEXPERIENCE Lab framework, feeding the ideation theme.
This 3DEXPERIENCE is showcasing Dassault Systèmes’ innovations at several events:
CES2016 (USA)
Laval Virtual 2016 (France)
Design in the age of Experience (Italy)
Future en Seine (France)

Zahner is an internationally acclaimed engineering and fabrication company best known for its highly crafted architectural metalwork.

One of Zahner’s recent projects, the Petersen Automotive Museum in Los Angeles, designed by Kohn Pedersen Fox (KPF), demonstrates how supply chain integration can help move complex buildings quickly to completion.

KPF principal Trent Tesch brought Zahner onto the project during its early stages to prove to the owner that the proposed façade — a complex swirling structure of stainless steel ribbons—would indeed be possible to fabricate.

The fabrication team began and lived in a 3D world from the beginning.

“We took the architect’s surface information and built out all of the parts based on their original 3D model,” says Mr. Shannon Cole, Zahner Senior Project Engineer.

The project called for the design of 26-foot long unitized pieces that spanned from one anchorage point to another.

“For the structural design, we laid out a wire frame and provided this to our structural engineer for analysis,” Cole explains. “This wire frame was then used to fabricate not only our scope, but the structural steel as well. Because [the architects] did their detailing in separate software, the next step towards actually building this was to bring it into our CATIA model as a cross-check to verify that they were providing the required geometry.”

Cross-checking geometry enabled Zahner engineers to accurately verify that each of the more than 300 unique ribbons were correct.

The team relied on CATIA to create knowledge patterns that could be adapted for each element. The CATIA software also enabled Zahner engineers to export and manufacture the parts.

As Cole explains, “From CATIA we had basic scripts that would export all the files to our shop in .dxf format. That’s what gets cut on our factory floor.”

While the process of designing each ribbon was fairly complex and required some design expertise, the fabrication and installation process was much simpler.

“Essentially, we’re building it twice,” explains Cole. “We build it once using CATIA, and then we build it again on our shop floor. So it’s important to get everything right when we build the design in the model, so that the fabrication and installation processes flow smoothly.”

This process of “building it twice” is executed in a managed structured engineering practice, similar to what you might find in the the construction field.

“We had a limited number of senior engineers who worked on this at the conceptual phase, and when production began we were able to bring in additional junior engineers who could smoothly transition into producing the additional system design work.

The model allowed them to quickly release a lot of parts to production based on the rules and knowledge patterns that were used,” Cole says.

The model kept installation simple as well.

“One of the most fantastic things about this is that there were a hundred parts unique to each and every one of these panels, but the way everything fit together for these elements, the parts checked each other,” Cole says.

The installation team used jigs to ensure the location of critical points on the product.

From there, the finish skins simply had to have their corners come together correctly to demonstrate accuracy.

“Everything went up in the field fantastically well,” Cole says.

He attributes the accuracy to reliance on and trust in a 3D model.

“Even when there were problems, the model allowed us to identify them early, we knew exactly what we were getting into at every step.”
