I got lucky. The owner/developer of a software corporation, Bentley Systems,… (1,034 words) - [why-do-we-need-better-vcs-equipment-the-pragmatic-answer.html](/content/why-do-we-need-better-vcs-equipment-the-pragmatic-answer.html) (1 words) - [They stood in opposition to the fusion of sound into silent film a hundred years ago](/content/2024/04/02/they-stood-in-opposition-to-the-fusion-of-sound-into-silent-film-a-hundred-years-ago-some-actually-did.html): Most apps in AEC (with the exceptions I mention often) enforce the non-fusion of two primary media types: drawings and models. It’s like forcing recorded sound a hundred years ago to remain NOT infused into silent film. There actually were people at the time (like Jack Warner) who argued that sound and film should always… (1,135 words) - [You have to be able to focus to clarity](/content/2025/03/01/you-have-to-be-able-to-focus-to-get-to-clarity/index.html): To keep people trapped either in unequipped 3D models, absent equipment for expressing and developing clarifying attentive focus within them, or, locked in flat model views that are effectively no different than any kind of technical drafting we've had for hundreds of years before computing, is missing the point entirely and throwing away tremendous opportunity..… (2,099 words) - [3D is not the evolution of 2D](/content/2024/07/31/3d-is-not-the-evolution-of-2d/index.html): Yeah, actually, no, 3D is not the evolution of 2D. Although, yes, the pull-quote below is a key concept we’ve all had in mind the last 20 years in architecture, engineering, and construction (AEC). 3D is the evolution of 2D.2D is a primitive representation of the 3D reality. Many people can not read or understand… (3,441 words) - [The problem with time travel](/content/2025/05/03/the-problem-with-time-travel/index.html): Through a remarkable set of circumstances, the relevant facts of which I'm not at liberty to discuss, I have just this weekend availed myself of the no doubt highly unique opportunity to take my pick from among an abundance of affordably priced used Time Machines, in the future, and used it to go back and… (2,443 words) - [**Technical drawing**](/content/2026/05/30/types-of-visualization-in-aec/index.html): Such a list is like any other list; no matter how many things you list, others will clamor to lengthen the list. I'm not interested in list exhaustion though, so I limit this to two types of visualization in AEC, both workhorses, the latter a war horse. Rendering, i.e., illustration. Technical drawing, i.e., construction drawing.… (540 words) - [About Rob Snyder](/content/about-2/index.html): Rob Snyder performed building design and construction documentation through digital modeling and technical drawing for 13 years in firms large and small including his own.

It's doubtful that pulling the rug out from under thinking, should be framed as challenging. It's something else entirely. Has anyone promoting the idea of eliminating drawings over the last 20+ years put any thought into what drawings are? Before devoting themselves to their elimination? In the 90s when I… (1,642 words) - [Pretty big jumps, into what?](/content/2026/01/15/pretty-big-jumps-into-what/index.html): Give or take a few years: 1983: software apps, for drawing lines, arcs, shapes, text... 1998: new features include the 4th iteration of a line trimming tool 2002: "drawings are just dumb lines and arcs"; it's Building Information Modeling (BIM) now! 2010: It's time for "Moving Beyond Geometry"; It's the "I" in BIM (data, "information")… (1,800 words) - [What I have to say about AI](/content/2024/11/29/what-i-have-to-say-about-ai/index.html): The fall back rhetoric now says : AI is for helping you think, not for thinking for you, but thinking with you, and, don’t fall behind others who are thinking in tandem with AI… because, they’ll replace you/your job. AI won’t. But they will.- the standard narrative The word abbreviated in “AI” undermines itself.

Here's how people closely look at, how they study AEC models to both develop and interpret them. It's what they think about, what they need to think about, and how they think about it. It's the actual function of drawing. It's all… (1,358 words) - [Eye Path Intentionality](/content/2024/08/01/eye-path-intentionality/index.html): Once you notice this it's hard not to think about it. You see it everywhere. Fundamental things about how vision works. I don't mean retinal absorption of light, for example. Although yeah, sure, that's there. That's part of it. Turn on the TV and no doubt you'll be presented with some science show getting into… (1,985 words) - [imagination is situated between our perceptions and our understanding](/content/2024/08/21/imagination-is-situated-between-our-perceptions-and-our-understanding.html): "… imagination isn't what we think, it's how we think. Now, I'd like to go to the originators of this, and that would be David Hume and Immanuel Kant, who noted that the imagination is situated between our perceptions and our understanding . As Kant wrote in 1780, that we do not see the world… (1,607 words) - [TGN](/content/tgn/index.html): Another part of the answer (to making tech work better in AEC) is the development of attention-focusing rigs addressing THIS problem:  the requirement in all modeled environments for a standardizable FORM of ENGAGEMENT with models that builds more thorough understanding faster, that draws focused attention to things that need to be understood, and provides both… (877 words) - [Any plan for the expression of these (5) functions within modeled environments?](/content/2024/09/12/any-plan-for-the-expression-of-these-5-functions-within-modeled-environments.html): OK, in general… Any plan for the expression of these (5) functions within modeled environments?

When was the last time you unfolded a paper map while driving? This is used as criticism of those in AEC who, while having digital models, still make drawings. But, would a model of… (1,016 words) - [Robert Snyder of OPEN VCS smiling with a humanoid robot servant](/content/2025/01/19/robert-snyder-of-open-vcs-smiling-with-a-humanoid-robot-servant.html): Someone kindly had an offline discussion with me which brought out something worth clarifying.
