WorldCAD Access

In Early Reviews, GPT-5 Flops

Opinion AI, the Theory: As it grows, it grows exponentially, until it eclipses the human brain. AI, the Practice: As it grows, it grows asymptotically, until it grinds to a halt under the weight of its innate limitations. - - - People on Bluesky had a hoot upon learning OpenAI's GPT-5 [which I've, for a hoot, nicknamed Generic Plagiarism Technology] Is behind schedule Suffers high computing costs Has access to limited high-quality training data (according to the Wall Street Journal [source]). - - - seed-corn-thoughts: Well, well, well, looks like we're probably at the top of the exponential growth curve...

The Wonders of the USB-C Port Extender

Opinion I really only cottoned on to the amazing properties of the USB-C port in the last year. Sure, my five-year-old phone has one, but that’s just for charging and data transfer, right? -- just like the prior standard, microUSB. Wrong-o! I’m surprised at how slow I was in taking full advantage of USB-C. It finally hit home when I realized my Dell laptop, which has the standard round-pin charging port, could also be charged through its USB-C port. I have two laptops on my desktop, and so I used a single multi-port USB-C charger to power both of them... Read more →

I Replaced My 14-year-old Desktop (Finally)

Opinion After 14 years, my Acer desktop computer needed replacing. It was a remarkable beast. Quiet, handsome, and powerful: 3.1GHz back when it was built in 2010. I updated the hardware a few time to maintain its speed over the years: Samsung solid state drive, a discrete graphics board for triple monitors, a USB 3 port expansion board, and the full 16GB RAM. Windows 7 is still being supported with regular security updates, surprisingly enough. But in late 2024 I made the decision to switch. One program I depend on -- Chrome Remote Access, to access this computer during my... Read more →

How I Came to Write 39 Books About BricsCAD. And Make 161 Videos

Opinion Sometimes, it’s useful to look back to see where you came from, and why you are the way you are today. You may well find a thread of events, of decision trees, and of opportunities taken -- or avoided. The most convoluted for me, perhaps, was how I came to produce so many books and training videos about BricsCAD. Each time an outside event changed my direction, I've noted it below as (Decision Tree). 1991: From AutoCAD to Corel Draw It began with Corel Draw. Or, rather, it didn’t. (Decision Tree.) In 1991, Wordware Publishing asked me to write... Read more →

Snaptrude AI Render

Opinion At a Webinar last week, Snaptrude, the company, introduced its rendering command. AI Render is part of Snaptrude, and not an add-on or external program. It works like this: 1. Provide it with a detailed model from Revit or Rhino, or else a massing model from Snaptrude. 2. Enter text that describes the kind of rendering you want. 3. Wait for the rendering to be generated. 4. Renders can be saved to disk or as views in the model. (The image at left shows three kinds of output from AI Render. All images are from screen grabs I made... Read more →

AI’s Alignment Problem

Opinion Geoffrey Miller wrote on Twitter [source], “If you understand the AI alignment problem, you understand that advocating for AI accelerationism means betraying humanity” [my italics]. He’s a professor of evolutionary psychology at the University of New Mexico. As I pondered the tweet, I began to realize that there is a vast gulf between the two, as they can never be reconciled: Alignment is an unsolvable moral problem Accelerationism is an unsolvable technical problem What Alignment Means Alignment means “encoding human values and goals into AI models to make them as helpful, safe, and reliable as possible,” IBM tells us...

I'm Satisfied. With My Cell Phone Plan.

Opinion I’m very satisfied with my cell phone plan, so when I get door-to-door salesmen bugging me to switch or send me offers by other means, I get annoyed. Not annoyed with other cell phone providers trying to get my business, but annoyed that it’s pointless, as none can beat the plan I have. When I tell them its features, the salesmen's eyes widen and they ask, “Who’s offering that?” I tell them that if I could do the research to find it, so can they. Actually, I’m cheating; you’re not going to find the plan I have. I started... Read more →

Repairing a 42-year-old Loudspeaker

Opinion In the 1970s and 1980s, when it was fashion to have big component stereo systems, and whenever my dad asked me to buy him another component, I’d use the opportunity to spend his money on stereo equipment that, in those days, I found interesting. Back then, components typically cost $300-$400 each -- multiply those by 3 for the cost in today’s inflated money. A typical stereo setup that a university student bought himself had a receiver (pre-amp, amplifier, and tuner in one), a tape deck, a turntable and a pair of speakers. So, we’re looking at nearly $4,000 in... Read more →

How Do You Solve a Problem Like Generative Design?

Opinion Generative design software isn’t as popular as it could be. In today’s green-aware environment, minimizing resources in manufacturing ought to be a no-brainer, a task at which generative design excels. And yet. There are reasons for the reluctance to deploy generative design. It has been expensive; Autodesk at one time charged US$8,000/year/seat (source), though now it’s less It’s an extra step in the manufacturing process: design -> generative optimization -> simulation -> machining The organic output typically is meshes or NURBS, which traditional MCAD programs find difficult to edit Its use of bone-growth algorithms (source) result in knobby-looking, spindly...

AI Isn’t in CAD

Opinion Generative design (image source Autodesk) Matt Lombard wrote about his thoughts of AI and CAD at https://dezignstuff.com/cad-and-ai, which caused me to think about what he said. There is a huge gap in what so-called AI can do now, and what we wish it could do to help take over tedious tasks: Step 1: AI is amazing! Step 2: ??? Step 3: AI is actually useful. As Matt noted, AI is mostly used by marketing, and AI firms are desperate to maintain their valuations by promising AGI RSN (real AI, real soon now). I think that what CAD vendors call...

I Can Understand Why Logitech Wanted to Charge for Software

Logitech's 25th anniversary ClearCase mouse Opinion The ceo of Logitech caused a stir, musing about charging a subscription for software that helps its hardware (source). We would be paying over and over again to use a really well-built, $200 mouse, she reflected. The idea was laughed off the pages of the tech press, the idea was retracted. Good Idea I think I understand why Logitech broached the idea. It writes software that lets us customize how the mouse works -- its buttons, its wheel, its motion, even options specific to specific applications. This costs money. Then, Logitech frequently updates the... Read more →

How I Lost Faith in iTunes

Opinion For music lovers in Canada, iTunes is pretty much our only go-to for buying albums online. I tried a few of the others, like Google Music and HMV, but I found them too painful to use. Despite trillionaire Apple taking 30% from struggling musicians, I liked that iTunes kept track of what I have already bought in my song library, now at 2,810 pieces. Also nice that Apple keeps a copy of all my purchases on the cloud. Should I lose a computer (as I once nearly did on a business trip through Stockholm airport), I can re-download my... Read more →

Prismatic Generative Design

Opinion Generative design optimization has a big problem, in my opinion. It’s been around for a long time (since 1994), and it seems to be just not that popular. Michael Bogomolny formed a new company whose InfinitForm software outputs prismatic generative designs that can be cut by regular machine tools, which are much more common, much faster, and much cheaper than 3D printing. I interviewed Mr Bogomolny last week. Here is our chit-chat, edited for clarity and brevity. Ralph Grabowski: I want to talk about your current company, InfinitForm, but also get a little bit of background on CogniCAD, your... Read more →

New CAD Systems For 2024

Opinion In the early days of the cloud, everything was going to run on it, according to the enthusiastic CEOs of certain CAD companies. Then reality hit, with users not necessarily keen to transition from desktop to cloud, and, worse, rewriting desktop software to work in multi-user, multi-server environments being hard enough that some vendors gave up on it. It’s easier to write new CAD software for the cloud from scratch, partly because user expectations of what desktop programs can do aren’t there. Over the last decade, numerous new ventures received funding to build on-line CAD programs. After a while,... Read more →

Reading Patent 11,977,821

Opinion In Canoa, the canvas is dimensionally unlimited (all images sourced from US Patent Office) The press release headline promised, “The Future is Here: AI-Powered Interiors by Canoa.” The text of the release explained what patent #11,977,821 granted Canoa: “The patent is the first to embed a learning algorithm directly inside of a CAD application and covers the generation of user-specific recommendations using their own clicks as prompt inputs.” I was intrigued, and set about to read the 52 pages of the patent, so that you don’t have to. It’s available through https://patents.google.com/patent/US11977821B1/. Overall view of how the method operates... Read more →

CAD Share Prices Falling

Opinion Publicly-traded CAD vendors, and ones that dabble in CAD, are not escaping today's stock market rout. Change in share price at this moment from a week ago: Trimble down 11%. PTC down by 8%. Autodesk down by 8%. Hexagon down by 7%. Dassault Systemes down by 6%. Nemetschek down by 4%. Siemens down by 3%. Read more →

Crowdstrike Strikes out

Opinion Image credit: @aaronoleary Crowdstrike provides Falcon threat checking software to approximately 60% of businesses running on Windows, and a software update shut all those computers down. The flaw crashed computers, because the software has root access -- the ultimate level of access. Twitter was unaffected, and so it let loose with real-time reports, fixes, and reactions. Here is some of the best of it. - - - Cameron Wilson: Reports of Windows computers showing BSOD errors across a lot of different sectors: supermarkets, banks, broadcasters, etc. Downdetector, which shows crowdsourced reports of outages, going crazy rn.

My Q&A With Siemens About Zel X

Opinion Assembly displayed by Zel X; image source Siemens Software The day before the Zel X PLM for SMBs launched, as I asked Siemens about the new product. Ralph Grabowski: Where did the unusual Zel X name come from? Siemens Software:In the product naming world, there are several different classes, including: descriptive (e.g. General Motors), evocative (e.g. Amazon), and invented (e.g. Pixar). We decided to take the invented name route, with a name that’s short and simple -- matching the easy-to-use and streamlined nature of the product itself. The X suffix indicates that Zel X is part of the Siemens... Read more →

Range Anxiety with Hybrid Cars

Opinion I switched from ICE (internal combustion engine) to hybrid when I bought my latest car, and gained a 50% improvement in gasoline mileage. It is a 2009 Ford Escape Hybrid. It's been interesting few months in learning how a hybrid differs from an ICE. It has a large, 400-volt battery that is charged by braking (called "regenerative braking") and by the gasoline engine. Whereas ICE has one mode (the engine runs all the time), this hybrid has three modes: Only the battery and electric motors power the wheels The gasoline engine assists the electric motors in accelerating, driving over...

My Notes from Qonic Talks 2024

Opinion User interface of Qonic About 136 people watched Qonic Talks 2024, brought to us by the folks who originally brought us BricsCAD. The intent of Qonic is to create a full BIM modeler, from concept design to detail design. But, they admit, that will take time. So, Qonic is working backwards: filling in details of BIM models and viewing existing BIM designs, which are imported from IFC, Revit, and Rhino. Qonic imports classification systems from bSDD [buildingSMART Data Dictionary]; importing of properties from bSDD will be available soon. However, no IFC spaces yet. In the model shown below, the...
