Autodesk 123D Catch for iPhone, New Tool for Engineers and Designers

Josh Mings — Thu, 13 Sep 2012 14:41:24 +0000

In Spetember of 1995, you couldn’t take photos with a phone and turn them into 3D data. Last week you couldn’t either. This week, you can. Hello future, nice to meet you. Yes, turning photos taken with your phone into a 3D model is now possible. Autodesk 123D Catch has been available for desktop and iPad, but now Autodesk brings the photo-stitching, mesh-generating app to iPhone, along with access to your data from the 123D web app.

123D Catch for iPhone

The 123D catch app has been out for the iPad since last May. This 1.0.2 update adds the iPhone support, better performance and the ability to access, view, share and edit your models on the 123D community site. If you’re not familiar with how 123D Catch works, here’s a quick video of it being used on an iPhone:

123D Catch for iPhone video

I’ve been waiting for this app on the phone for years. There’s a lot of novelty to it and they’re targeting the mainstream market with this, but the ability to snap some photos and download an OBJ of the model, makes the app an amazing asset for capturing data for reference models. I want to say engineering and design will never be the same again. We could do this months ago with camera or iPad–perhaps it’s just that this is now possible with something so common as a phone. Maybe it doesn’t match the resolution of a laser scanner (yet), but photographing a site installation, taking back to the office and provide a digital representation to design, engineering and the shop floor is just… wow.

New 123D Catch Features:

Take photos with your iPhone 4/4S, upload to Autodesk Cloud for 3D conversion
New capture window and controls to manage focus, exposure, and more
Review, delete or retake over/under-exposed photos for better 3D models

Navy, Marine Corps Will Seek Allies’ Cooperation in Asia-Pacific

Dan Parsons — Thu, 13 Sep 2012 11:05:12 +0000

By Dan Parsons

PANAMA CITY, Fla. — A U.S. defense budget crunch will force the Navy and Marine Corps to lean on regional partners to establish a constant presence in the Pacific, officials said.

Within 10 years, Marines will be spread across the Pacific theater, stationed on a rotating basis everywhere from Darwin, Australia, to mainland Japan, said Marine Corps Lt. Gen. Thomas L. Conant, deputy commander of U.S. Pacific Command. With such a distributed force -- the largest concentration of which will be 11,500 Marines in Okinawa -- the "distances alone can defeat your efforts,” Conant said.

The challenge is how to cover an enormous expanse with existing ships and a dwindling number of troops, said Undersecretary of the Navy Robert O. Work.

For that reason, Marine Corps and Navy leadership are seeking regional partners to close the gaps. Modern, more flexible ships and weapon systems also will be key to executing the U.S. strategy in the Pacific, Work said.

“We can’t afford very expensive platforms,” said Work. “We’ve got to make the platforms we have better.”

In an endorsement of the Littoral Combat Ship, Work cited the vessel to hype “capability containers” as the future of naval shipbuilding. Together with the newfangled Forward Afloat Sea Base and the introduction of the F-35B short takeoff and landing Joint Strike Fighter, the Navy and Marine Corps’ force will have advanced capabilities, Work said.

The Navy will be seeking “energy efficient vessels with smaller crews” that save money while delivering capabilities equal or better than currently available, Work said.

“The people who cry about [the LCS’] capabilities are missing the forest for the trees,” Work said.

The ship’s open payload space, like that of a large-deck amphibious ship or the joint high-speed vessel, is prime real estate for Marines, aircraft, ground vehicles or unmanned systems. The same goes for the afloat forward sea base, which at $600 million is a relative bargain compared to a $12 billion aircraft carrier.

“It’s just a big box,” Work said. It what goes inside that counts, he added.

By 2020, 60 percent of the Navy’s fleet — including 6 of 11 aircraft carriers — will be based in the Pacific. That will happen regardless of defense spending cuts, Work said. The availability of 11 aviation-capable amphibious ready groups means the U.S. presence worldwide could jump from 11 aircraft carriers to 22, he said.

Using forward sea bases, of which two are planned, the military then has another platform from which to launch helicopters and smaller craft. Those aircraft and small boats will carry unmanned vehicles that extend their reach, he said.

Work noted that much of the ongoing planning could be jeopardized if Congress allows sequestration — the automatic, across-the-board 10 percent cut to defense spending looming on Jan. 2 — to occur, he said.

“The big unknown is sequestration,” Work said. “You could not implement the current strategy at the sequestration level. At the current level, it’s hard but manageable. At the sequestration level it becomes hard and unmanageable.”

Solid Edge ST5 third party apps

DEVELOP3D — Thu, 13 Sep 2012 09:49:27 +0000

With the launch of Siemens PLM’s latest release we look at seven of the best add-on products for Solid Edge.

SimpoEdge

Supplier Simpoe
Description SimpoEdge is a plastic injection simulation solution integrated into the Solid Edge graphic user environment, which can optimise the design and tooling of plastic parts.

Injection mould tool simulation is all about reducing the risk of errors in production by giving the design and manufacturing team insight into how a tooling stack will operate based on a given configuration of geometry (part design, gating and runner design) and operating parameters (such as melt temp, pressure, as well as cooling channel design).

The program runs within the familiar Solid Edge user interface, making it relatively simple to operate the powerful pre–and post processing technology, with the idea being to ‘close the loop’ of plastic part design and manufacturing optimisation, however complex the geometry of shell and solid parts.

With plastics in mind, SimpoEdge has a number of features for packing simulation, thermal exchange regulation, and even for simulating the complete part deformation due to warping and material shrinkage, as well as the material database of more than 5,000 materials, which can also be customised with a few clicks.

The base package (SimpoeXplorer) includes all this, plus there are three variations that add on specific benefits for engineers, toolmakers and manufacturers such as multiple gate optimisations, and cooling simulations.
Price On application

EcoDesigner

Supplier Trayak
Description Originally released with Solid Edge ST3, EcoDesigner has become one of the established green product design applications, tightly integrated into the CAD package.

The software allows the product engineer to easily analyse the environmental impact of the design using a Life Cycle Analysis (LCA) ‘first pass’ that works directly on parts, assemblies and sheet metal components before you go too far.

It offers the flexibility to choose an impact assessment method and indicators that make the most sense for your products, operating conditions, geography and industry.

Working from peer reviewed and industry accepted data sources for its analysis, EcoDesigner is also an open architecture system that allows a company to add in its own proprietary material and environmental analysis data.

On install, it supplements the entire existing Solid Edge materials library with the LCA data required for each entry.

The system automatically picks up any assigned material, weight and volume of all the parts in the assembly for the user to then experiment with different materials.

The ST5 release offers new functionalities such as multiple part changes in one easy form; graphical visualisation of best and worst parts in the assembly, and the ability to run, compare, save and load different scenarios based on materials, processes and even transportation data.

Inforbix

Supplier Inforbix
Description For Solid Edge users, a big challenge is presented by the growing amount of product data, and how to aggregate, access, and find the product data they need simply and quickly from across various locations and file types and locations throughout the company.

Think of Inforbix as an online, cloud–based, product data searchengine for CAD that enables Solid Edge users to find and extract data and reduce the time lost or wasted searching for information, while effectively increasing product data reuse.

It is used not through Solid Edge, but via a standard web browser, and can easily access product data within CAD, PDM, and PLM.

All Inforbix apps utilise product data semantics technology that automatically infers relationships between disparate sources of data. For example, Inforbix can semantically connect or link Solid Edge CAD assemblies with a related Excel or PDF file containing a bill of materials table stored on a file server in another department.

A big benefit here is that users are made aware of useful data they may not even know exists, while the source material isn’t actually touched, moved, or migrated to the cloud.

SigmaNEST

Supplier SigmaTEK
Description SigmaTEK is a provider of manufacturing process efficiency software, with its flagship product SigmaNEST being one of the leading CAD/CAM ‘nesting’ softwares.

Its program takes a 3D model from Solid Edge, automatically strips it into the necessary parts for cutting, and ‘nests’ the parts in the most efficient and effective manner possible from your predefined sheet materials.

Slashing scrap and maximising machine cutting efficiency and time for all cutting, punching and router machines.

This is perfect for Solid Edge’s vast user–base in the manufacturing sector including metal shops, steel service centres, OEMs and suppliers of all types and sizes, allowing them to maximise throughput and significantly reduce overheads.

Version 9’s user interface uses a familiar menu ribbon making it simpler to use, while new part/sheet fill colour combinations allows for better visualising and distinguishing parts. Meanwhile a selection of intuitive icons and the ‘Quick Find’ and ‘Feature Tree’ functionalities helps speed up the process.

Increasing material cost savings is the big plus with SigmaNest, while the software itself is flexible enough to incorporate a wide range of machinery, regardless of type or brand, making it a singlesource programming base for production engineers.

Moldex3D eXplorer

Supplier Moldex3d
Description Moldex3D eXplorer is a quick part verification tool embedded into Solid Edge giving industrial designers an easy to understand validation tool to check parts for manufacturing
when creating a CAD model.

With its professional filling analysis capabilities, major moulding problems, such as flow imbalance, air traps, weld lines, and design mistakes can be simulated and discovered in the early design phase, enabling the user to spend more time on the designs.

It’s a versatile product, cutting out the need to simplify designs into 2D plans, and letting you export your models in neutral formats such as IGES, STEP or STL, or as a part geometry, runner layout and cooling channel layout from the CAD.

Any detailed definition that needs to be added can be done using Moldex3D Designer or Moldex3D Mesh.

For those of you hooked on hardware speeds, Moldex3D eXplorer utilises each core of the modern CPU architecture (maximum four cores) for its quick analysis. Once completed, a report generator enables users to share reports with the product design team, clients, suppliers and moulders.

It has a diverse impact on many industries, regardless of how delicate or complex the product design. It’s a great tool for predicting potential mouldmaking blunders.

Smap 3D Piping

Supplier SMAP
Description Developed for planning complex 3D piping systems for machinery and production plants Smap3D Piping is completely integrated into Solid Edge via its XpresRoute add-on.

Solid Edge’s PathXpres within XpresRoute enables designers to rapidly define a 3D tube or piping path without drawing the individual lines of the path, generating the optimum route for it to take.

The addition of SMAP’s software ensures that the complete piping assemblies are generated along the path automatically, using the correct bends, pipes, tees and flanges.

It includes an extensive library of different types of piping and many intelligent functions: should a change be made along the design, it automatically swaps all the components and pipes that are affected by the change.

The user can also define new pipe classes very easily by setting the material, diameter, pressure, temperature and so on for the individual components. SMAP 3D also supports the production of pipe bends or specially adapted curved pipes, besides standard curved fittings, as a basic function.

With Solid Edge customers producing large–scale machinery and even plant designs, SMAP covers P&ID diagrams, 3D planning and accurate isometrics, automating the designs to help save time and
cost while avoiding the need for expensive reworking.

PARTshare

Supplier Striker Systems
Description Striker Systems’ PARTshare is an advanced library system that provides storage and retrieval of sheet metal parts and assemblies along with any associated manufacturing data, allowing Solid Edge users to share flat part data with CAD/CAM and Nesting software in real-time.

Working directly within the Solid Edge user interface, individual sheet metal parts or entire assemblies can be released from the Solid Edge modelling environment, automatically unfolded (as necessary) and placed in the PARTshare library.

Critical part data including part number, revision, and material parameters, are all maintained to facilitate manufacturing operations.

Once the parts are in the PARTshare library they are immediately available to users of Striker CAD/CAM and Nesting software (needing no further importing of parts) and can be individually programmed or nested for CNC punching and cutting machines.

This is for a larger outfit, with a typical configuration for PARTshare including several Solid Edge designers and one or two Striker CAD/CAM programmers, all accessing a common library, although, comparing this to the conventional method of opening each Solid Edge part model individually and saving a flat part, the timesavings can be huge.

SolidWorks 2013: Raising the spectre of backwards compatibility

DEVELOP3D — Wed, 12 Sep 2012 21:08:38 +0000

This has been the holy grail for CAD users since time immemorial. The ability to take data from a current version of your CAD system and allow users with a preview version to open it, use it and work with it as native data. And it’s not particularly common that this possible.

The reasons for this are pretty obvious once you look at the Terminator-like future events influencing the past type of conundrum. There are also very obvious reasons why CAD vendors aren’t all that keen. And by all that keen, I mean, they’d rather see their first born sent to the Mayans temples as an offering. But first, let’s explore why it’s often an issue. And to do that, you need to understand how forward compatibility works.

Bipartisan Group of Former Lawmakers Push Congress to Reach Budget Deal

Sandra Erwin — Wed, 12 Sep 2012 19:30:19 +0000

Body:

By Sandra I. Erwin

A coalition of former U.S. House and Senate members has launched a three-week offensive to try to break the legislative logjam that threatens to create further economic damage to the United States.

The group also is seeking to influence the upcoming presidential and congressional elections by raising public awareness of the nation's fiscal crisis, in hopes that average citizens will demand action from their candidates.

The drumbeat of doom continues to get louder as the United States heads towards a "fiscal cliff" in 2013 — a combination of tax increases and spending cuts scheduled to take effect that, economists project, will drive the nation back into a recession.

A deficit-reduction deal to avert the fiscal cliff would be relatively easy to achieve, if only members of Congress put their country's best interest ahead of partisan politics, said former U.S. Sen. Sam Nunn, D-GA.

Nunn, along with eight other former U.S. lawmakers, spoke Sept. 12 at the inaugural event of "Strengthening of America," the first of four forums planned over the next 20 days.

The overwhelming consensus among the panelists: The current stalemate over federal spending and taxes is driving the U.S. economy and global standing into a ditch. They also insisted that the crisis easily could be avoided if political leaders acted like adults and stopped playing budget chicken.

The panel's message took on added urgency as credit ratings agency Moody's announced it is considering downgrading the U.S. AAA credit rating if Congress doesn't act soon to avert the fiscal cliff. The current federal deficit is about $1.1 trillion. The nation's public debt of about $16 trillion now exceeds the U.S. Gross Domestic Product.

The retired lawmakers insisted that they are not trying to reinvent the wheel by proposing a new deficit-reduction plan. Broad guidelines already have been put forth by the National Commission on Fiscal Responsibility and Reform — known as the Bowles-Simpson commission co-chaired by Alan Simpson and Erskine Bowles. The commission was created in 2010 by President Obama. Other recommendations could be drawn from the Domenici-Rivlin task force, led by former U.S. Sen. Pete Domenici, R-N.M., and former budget director Alice Rivlin.

The outline for a budget deal is in place, Nunn said. “All that's missing is willingness to take action,” he added. "This is not a complicated calculus or physics problem," Nunn said. "The hard part is making political choices ... and having an honest discussion of our fiscal challenges."

The nation's debt is growing faster than the economy. As a result, it will become tougher for the United States to keep borrowing money at today's historically low interest rates. A long-term deal including both spending cuts and tax increases would help restore confidence in the United States and keep interest rates from soaring, said former Secretary of State James Baker, who joined the panel via satellite.

The threat of the fiscal cliff is real, Nunn warned, as economists have concluded that sharp immediate cuts in spending and sharp rise in taxes will push the nation back into recession.

Nunn called for the current Congress to come to its senses. "The parties spend time and attention blaming each other," said Nunn. The endless finger pointing only puts off the inevitable compromise that eventually both parties will have to reach. "There is no chance that one party will be able run over the other and impose their perfect solution," Nunn said.

Domenici, one of the nine former lawmakers on the panel, said it would be naive to expect a "grand bargain" agreement over the lame-duck session after the election. "There is not enough time," he said. Even a partial "down payment" deal to reduce the debt would be unrealistic in that short amount of time. "That's a fool’s errand," he said. "It's going to be just as hard to get a down payment as a grand bargain."

So what can be done? It's simple, said Domenici. During the lame duck session, Congress should agree on the size of the deficit reduction package, and set a timeline. He suggested Congress should adopt Simpson-Bowles' goal of $4 trillion in debt reduction over 10 years — $3 trillion in cuts, $1 trillion in new tax revenue. Lawmakers also would have to a set a series of milestones for calendar year 2013 that would lead up to a grand bargain. An enforcement mechanism, too, would be necessary to ensure the deadlines are met. Another "sequestration" scenario would not be out of the question, Domenici suggested.

The second "Strengthening America" forum is scheduled for Monday Sept. 17, when the panel will discuss the national security implications of the rising U.S. debt. Guest speakers will include former Defense Secretary Robert Gates and former Chairman f the Joint Chiefs of Staff Adm. Mike Mullen. Deficit-reduction gurus Simpson, Bowles, Domenici and Rivlin also are on the lineup

On Sept 27 the group will host an event in New York City focused on tax reforms. On Monday Oct. 1, they will talk about health care and entitlement programs' cost control, which Nunn categorized as the "most important and difficult challenge."
