Local Simulation Feature To Be Removed From All Autodesk Fusion 360 Versions

The removal of features from Autodesk products would appear to be turning into something of a routine at this point, with the announced removal of local simulations the latest in this series. Previously Autodesk had severely cut down the features available with a Personal Use license, but these latest changes (effective September 6) affect even paying customers, no matter which tier.

While previously executed local simulations on designs will remain accessible, any updates to these simulations, as well as any new simulations will have to use Autodesk’s cloud-based solver. This includes the linear stress, modal frequencies, thermal, and thermal stress simulation types, with each type of simulation study costing a number of Cloud Tokens.

Solving a linear simulation should initially cost 0 tokens, but the other types between 3 – 6 tokens, with the exact cost per token likely to vary per region. This means that instead of solving simulations for free on one’s own hardware, the only option in a matter of weeks will be solely through Autodesk’s cloud-based offerings.

Naturally, we can see this change going over exceedingly well with Fusion 360 users and we’re looking forward to seeing how Autodesk will spin the inevitable backlash.

(Thanks, [Jeremy Herbert] for the tip)

Bartop Arcade Machine That Isn’t Afraid Of Change

Arcade machines have a distinct look and feel with large imposing cabinets and smaller bartop machines that try to keep the look and feel of a traditional upright arcade cabinet while taking up less space. An entirely new aesthetic has been given for this engineering marvel of a bartop arcade that [DIY Engineering] has made. Gone is the expansive angular box, and in its place are sleek and slender curves. The key piece that makes this build work is the curved monitor.

He started with a detailed design in Fusion360 that really focused on the tools and techniques that [DIY Engineering] knew would work. The backbone of the device was formed from wooden dowels around which 3d printed parts slid on. To the sides of the dowels, two pieces of acrylic are screwed on to act as an LED diffusor. To that acrylic, two pieces of CNC’d red oak are attached with two arcade buttons for pinball-style actuation. Over the top, cast acrylic was heated and then bent into the desired shape with the help of a two-part mold press. The screen slotted right in perfectly. Part of the display at the top was reserved for a marquee, and the look is extraordinary with the dark acrylic. Ten arcade buttons and an eight-way joystick offer an array of options for input.

Internally, a temperature-controlled fan and a Raspberry Pi are running the show. Controls are wired as GPIO and read by the Pi. So naturally, the games on the SD card tend to look best on a long vertical screen: vertical shooters and the like.

Arguably, the best thing about this project isn’t just the execution (which is fantastic) but the look behind the curtain at the process. So many potential problems were solved in the modeling stage, and fabrication went fairly smoothly as a result (or so we think youtube hides a multitude of sins). The results speak for themselves, and we think this is an enviable arcading machine. [DIY Engineering] has mentioned providing files in the future for you to build your own. If perhaps it seems a little intimidating, why not give a smaller 3D printable bartop a try?

A Simpsons TV For A Golden Age

While the pace of technology continues to advance at breakneck speed, certain things in the past are left behind largely subject to the whims of nostalgia. Televisions, for example, are lighter, cheaper, and bigger than they were in the early 90s, but they did have a certain design aesthetic that doesn’t exist anymore. Meanwhile, Simpsons episodes have been (arguably) on the decline since the golden age of the 90s, so [buba447] decided to combine these two facets of a nostalgic past into a custom TV that only plays these older Simpsons episodes.

Update: Now there’s a build guide.

The TV is 3D printed but takes design cues from CRT-based technology from decades past. It even has working knobs emblematic of that era as well. Inside the “television” is a Raspberry Pi which is hooked up to a small screen. The Pi powers up and automatically starts playing Simpsons episodes once it boots. There is a power button at the top of the TV which mutes the sound and also turns off the display. As an added touch, the display outputs in 640×480 resolution, which is also somewhat historically accurate, even if the TV itself is much smaller than its ancient relatives.

Of course, the TV only plays episodes from The Simpson’s first eleven seasons, which includes all of the episodes of The Simpson’s golden era (and a few extra) and omits those episodes from the modern era, which will please certain Simpsons fans as well. This actually isn’t the first time we’ve seen a 24 hour Simpsons device. This Pi-based build serves up Simpsons episodes nonstop as well, but sends them out over the airwaves instead.

Autodesk Blinks, Keeps STEP File Export In Free Version Of Fusion 360

Good news, Fusion 360 fans — Autodesk just announced that they won’t be removing support for STEP file exports for personal use licensees of the popular CAD/CAM platform after all.

As we noted last week, Autodesk had announced major changes to the free-to-use license for Fusion 360. Most of the changes, like the elimination of simulations, rolling back of some CAM features, and removal of generative design tools didn’t amount to major workflow disruptions for many hobbyists who have embraced the platform. But the loss of certain export formats, most notably STEP files, was a bone of contention and the topic of heated discussion in the makerverse. Autodesk summed up the situation succinctly in their announcement, stating that the reversal was due to “unintended consequences for the hobbyist community.”

While this is great news, bear in mind that the other changes to the personal use license are still scheduled to go into effect on October 1, while the planned change to limit the number of active projects will go into effect in January 2021. So while Fusion 360 personal use licensees will still have STEP files, the loss of other export file formats like IGES and SAT are still planned.

Hackaday Links: September 20, 2020

The announcement of Autodesk’s changes to the Fusion 360 personal use license terms this week caused quite a dustup. Our article on the announcement garnered a lot of discussion and not a few heated comments. At the end of the day, though, Autodesk is going to do what it’s going to do, and the Fusion 360 user community is just going to have to figure out how to deal with the changes. One person who decided to do something other than complain is Justin Nesselrotte, who came up with a quick and easy bulk export tool for Fusion 360. This gets to the heart of the issue since the removal of export to STEP, IGES, and SAT files is perhaps the most painful change for our community. Justin’s script automatically opens every design and exports it to the file type of your choice. Since the license changes go into effect on October 1, you’d better get cracking if you want to export your designs.

Over on Twitter, Hackaday superfriend Timon gives us a valuable lesson in “you get what you pay for.” He found that a bunch of his header pin jumper cables weren’t even remotely assembled properly. The conductors of the jumper wire were only loosely inserted into the terminal’s crimp, where apparently no crimping pressure had been applied. The wires were just rattling around inside the crimp, rather than making sold contact. We’ve covered the art and science of crimping before, and it’s pretty safe to say that these jumpers are garbage. So if you’re seeing weird results with a circuit, you might want to take a good, close look at your jumpers. And as always, caveat emptor.

The GNU Radio Conference wrapped up this week, in virtual format as so many other conferences have been this year, and it generated a load of interesting talks. They’ve got each day’s proceedings over on their YouTube channel, so the videos are pretty long; luckily, each day’s stream is indexed on the playbar, so along with the full schedule you can quickly find the talks you’re interested in. One that caught our eye was a talk on the Radio Resilience Competition, a hardware challenge where participants compete head-to-head using SDRs to get signals through in an adversarial environment. It sounds like a fascinating challenge for the RF inclined. More details about registering for the competition can be had on the Radio Resilience website.

You know those recipe sites that give you a few choices on what to make for dinner based on the ingredients you have on hand? We always thought that was a clever idea, and now something like it has come to our world. It’s called DIY Hub, and it aims to guide makers toward projects they can build based on the parts they have on hand. Users create projects on the site, either hosting the project directly on the site or providing a link to projects on another site. Either way, the project’s BOM is cataloged so that users can find something to build based on parts stored in their “Garage”. Granted, most of us suffer from the exact opposite problem of not knowing what to build next, but this could be an interesting tool for stimulating the creative process, especially for teachers and parents. It’s currently in beta, and we’d love to see a few Hackaday.io projects added to the site.

And finally, we got a tip to an oldie but a goodie: How to Build a Castle. No, we don’t expect to see a rash of 13th-century castle builds gracing our pages anytime soon — although we certainly wouldn’t be opposed to the idea. Rather, this is a little something for your binge-watching pleasure. The BBC series, which was actually called Secrets of the Castle, was a five-part 2014 offering that went into great detail on the construction of Guédelon Castle, an experimental archaeology project in France that seeks to build a castle using only the materials and methods available in the 1200s. The series is hosted by historian Ruth Goodman and archaeologists Peter Ginn and Tom Pinfold, and it’s great fun for anyone interested in history and technology.

Distance Learning Land

[familylovermommy] has been homeschooling her kids even before the pandemic, so she’s pretty well-versed on being a learning coach and a teacher. One of the activities she designed for her boys has them creating 3D models using Tinkercad. In the spirit of openness and cultivating freethinking, she did not give them very many constraints. But rather, gave them the liberty to creatively design whatever scene they imagined.

In the Instructable, she shares her sons’ designs along with instructions to recreate the models. The designs as you’ll see are pretty extensive, so she embedded the Tinkercad designs directly into it. You can even see a number of video showcases as well.

This is a really cool showcase of some pretty stellar workmanship. Also, maybe a bit of inspiration for some of our readers who are creating work from home activities of their own.

While you’re at it, check out some of these other work-from-home hacks.

Autodesk Announces Major Changes To Fusion 360 Personal Use License Terms

Change is inevitable, and a part of life. But we’re told that nobody likes change. So logically, it seems we’ve proved nobody likes life. QED.

That may be a reach, but judging by the reaction of the Fusion 360 community to the announced changes to the personal use license, they’re pretty much hating life right now. The clear message from Autodesk is that Fusion 360 — the widely used suite of CAD and CAM software — will still offer a free-to-use non-commercial license for design and manufacturing work, with the inclusion of a few very big “buts” that may be deal-breakers for some people. The changes include:

  • Project storage is limited to 10 active and editable documents
  • Exports are now limited to a small number of file types. Thankfully this still includes STL files but alas, DXF, DWG, PDF exports are all gone
  • Perhaps most importantly to the makerverse, STEP, SAT, and IGES file types can no longer be exported, the most common files for those who want to edit a design using different software.
  • 2D drawings can now only be single sheet, and can only be printed or plotted
  • Rendering can now only be done locally, so leveraging cloud-based rendering is no longer possible
  • CAM support has been drastically cut back: no more multi-axis milling, probing, automatic tool changes, or rapid feeds, but support for 2, 2.5, and 3 axis remains
  • All support for simulation, generative design, and custom extensions has been removed

Most of these changes go into effect October 1, with the exception of the limit on active project files which goes into effect in January of 2021. We’d say that users of Fusion 360’s free personal use license would best be advised to export everything they might ever think they need design files for immediately — if you discover you need to export them in the future, you’ll need one of the other licenses to do so.

To be fair, it was pretty clear that changes to the personal use license were coming a while ago with the consolidation of paid-tier licenses almost a year ago, and the cloud-credit system that monetized rendering/simulation/generative design services happening on the Autodesk servers. Features removed from the free license in this week’s announcement remain in place for paid subscriptions as well as the educational and start-up license options.

The problem with these personal use licenses is that it’s easy to get used to them and think of them as de facto open-source licenses; changing the terms then ends up leaving a bad taste in everyone’s mouth. To their credit, Autodesk is offering a steep discount on the commercial license right now, which might take some of the sting out of the changes.

Update 09-25-2020: Autodesk has announced that STEP file export will remain in the free version of Fusion 360
