Is CAD Becoming More Portable?

For years now I’ve been writing on the topic of CAD software running on mobile devices. As more and more of engineering and manufacturing tasks become distributed among various partners and suppliers in ever-expanding supply chains, having a way to access drawings and models on mobile devices (tablets, smartphones, etc.) has become more important.
Obstacles Abound
Critics—for myriads of technical reasons—don’t believe that mobile CAD is anything but a pipe dream of vendors looking for additional ways to deliver software as well as the potential of a new revenue stream for their products. Though most of the apps are free, as the market grows and demand increases, there is always the possibility that users will eventually be willing to pay for mobility. There are also concerns regarding security as mobile devices can’t be regulated and managed by IT in the same manner as desktop computers.
The Current State of Portable CAD
Autodesk was the first vendor to jump into the not-yet-tested waters, offering AutoCAD WS (now called AutoCAD 360), a free drawing and drafting app that enables users to view, edit and share AutoCAD drawings on the go. Available for free on both on the Apple store and Google Store, AutoCAD 360 has been downloaded five million times, though how that equates to the number of actual users is not completely clear.
Ralph Grabowski, an industry analyst, follows the portable CAD market closely and has just released his State of Portable CAD in 2013 report, featured in his weekly upFront.ezine. One of the drawbacks he sees with portable CAD—and one quickly identified with early critics—is the reality that CAD is very hardware-intensive and the portable devices don’t yet have the computing horsepower to run it effectively.
With limited RAM capacity on mobile devices, it’s difficult to cram the operating system, CAD program, and all the drawing data into .5 GB of RAM. On the graphics side is another lingering issue, as users can’t simply swap in a faster, CAD-friendly graphics board. For developers, another issue revolves around the question of how to write apps for iOS with Apple’s secrecy (most hardware specs are unknown), while writing for Android is also tricky because of device targeting.
Have no fear; the hardware problems will resolve themselves, as developers are already upping available RAM and GPU specs are on the upswing. Quad-core CPUs running at 1.5 GHz or faster are now common, while units with a whopping 8 cores of processing power and/or with speeds of over 2.5 GHz are beginning to ship.
How do vendors make money selling CAD apps?
Technical issues aside, there is also the lingering question of exactly how vendors would make money selling portable apps as nearly all of them are free, especially after Apple takes its 30% cut. So this begs the question: how do CAD vendors pay for the cost of developing apps when most of them aren’t charging for them?
There are exceptions. Autodesk is charging for its AutoCAD Pro and Pro Plus apps ($49 and $99/year respectively). IMSI/Design, developer of TurboViewer, is also charging for its higher-end TurboViewer X, TurboViewer Pro, and TurboReview ($6.99, $29.99 and $49.99, respectively) though special pricing of those packages is available.
AutoCAD 360
AutoCAD 360 is a free drawing and drafting mobile app that allows users to edit, view and share AutoCAD drawings from anywhere.
An alternative pricing model ties the mobile apps to desktop software, making the free mobile app useless unless the user is paying for the desktop version. Vendors trying out this pricing structure include Geometric, with its Glovius software, Simens PLM Software with its Solid Edge Mobile, Nemetschek Vectorworks with its Nomad software, and Vizerra with its Revizto Viewer.
The bottom line
Though some of the pricing quoted here may have changed, it’s a good landscape to view the general market for mobile CAD applications. While most vendors understand that there is a need for portable CAD, finding out how to actually make money at it in the short run might prove problematic.
We’ll certainly keep an eye on this emerging new market and hope to see progress—both on the technical side and the business side—so designers and engineers will have the CAD apps they need to become increasingly productive when they are out of the office or on the road.

Some basics and how it works in conventional CAD

1. Reverse engineer from scanned photo tracings. Sometimes, I wanted to reverse engineer a part where I didn’t need precise measurements for most of its geometry. Remodeling from a photo, along with calipers when I needed more resolution, has proven to be a very efficient approach. One particularly compelling trick is to put flanges and other flat interfaces directly on the glass of the office scanner. Sketching over those images easily achieves similar resolution to most 3D printers. Years ago, I modeled most of the castings on this ‘78 Beetle Transmission in SpaceClaim by tracing carefully taken photographs and scans of its flanges. 2. 3D sketch on top of images. The next step is to try actual 3D sketching on top of images. Below are some examples I did by 3D sketching on MC Escher lithographs using a technique substantially similar to the basic approach used in the video. 3D models from photos  Now let’s take a look on how to to accomplish this basic tric...

Altair Solid Thinking: Conceptual Design Inspired by Bone Growth

The concept of a part taking shape as it reacts to its environment may be new to engineers, but nature has been doing this for a long time. Take for instance the evolution of bones—long skeletal bones will grow and change shape as they are subjected to loads and boundary conditions. Altair’s solidThinking has programmed this bone-like behaviour into Inspire, a concept modeling application for mechanical design. Essentially, Inspire uses a bone growth algorithm to create the shape of a part from little more than loads, boundary conditions and a space that represents a maximum build volume. Inspire is an interesting example of early concept CAE design. Instead of bringing simulation into the initial CAD design, Inspire works backwards. It will “grow” a near optimal concept using FEA simulations. “Inspire is based on human bone growth algorithms developed at the University of Michigan in the mid ‘80s,” said Kroeger. “We mimic what nature would do. We took this high-end engineering...
