I used to wonder why studded Technic went away. Turns out it actually didn't, it was just absorbed by System

[Xfing]

I recently checked out the build process for Lego City's 2025 yellow bulldozer and being someone who greatly appreciates using any and all types of elements to achieve stunning results, I was very happy with what I saw. Studded Technic used liberally, and not just for structure, but also for function - leveraging both of its advantages. Axles, half axles, pins and connectors present in multitudes. Seamlessly mixed with both System parts and studless Technic - the latter understandably chosen for situations where full range of mobility is preferable (old studded Technic models often had their moving parts get stuck). The final model both looks great and has genuine functions not in any way inferior to smaller Technic sets from some years ago.

So basically what you end up with is basically a wholesale Modelteamization of Lego System, and I'm here for every bit of it.

But the free-for-all approach of System model designers has had the unintended consequence of Technic losing quite a bit of its identity over the years. If System models can use all of System parts, ball joints, studded Technic and studless Technic, then how to keep the line distinct? Lego's answer was simply to restrict themselves to the studless Technic building system for everything - since after all, there are no models like that outside of Technic (well, unless you count Racers), so it's easy to say that's how to define Technic. But while mechanically sound, the studless Technic system initially left the models looking skeletal and frankly unappealing compared to what can be built with System. Sure, some studded Technic looked skeletal too (in fact the larger the scale, the more they did), but in the earliest years of Technic that actually wasn't always that big a problem, just due to the sheer amount of plates and even bricks that were used. Right before the transition to fully studded, Lego have found ways to greatly improve the look of their Technic models. Studless needed a whole new solution though, and that solution ended up being the panels.

Still, it seems like while the gifts of Technic have seen wide and frankly ubiquitous use, the line itself seems to be trying to distance itself as far as possible from the rest of Lego and there seems to be a strong insistence on only using studless Technic elements in the sets. Competitors who hire MOCers don't seem to restrict themselves like that and use System pieces liberally where appropriate - then again those competitors don't have to worry about differentiating their product lines, since the categories of their offerings are much narrower.

What do you think?

I don’t think Technic went studless to differentiate itself from system. I think it went that way as the smooth studless beams and panels look better than studded bars and plates.

Well, we had these discussions before - the "studful vs studless" threads, the real Technic vs ... unreal Technic. I am building with LEGOs since 1965. I never got the severe restrictions the studless approach imposes, which is in my opinion simply not representing the LEGO system (not LEGO SYSTEM). And for decades, it had not been like that. Technic was for decades studful, heck, in the 1980s virtually every Technic construction piece had studs. Then came a time, when resentments regarding studs in Technic world were building-up, cumulating in "those who use studded pieces in Technic-labelled models don't master Technic". All discussed here on EB, certainly not only driven by TLG.

For me, the thing is: I never ever cared nor will I care about that (studless) Technic label. Man, today's pure Technic sets, nicely panelled, still look like machine gun treated models. Maybe TLG should invent Technic hole pops. Which you'll hardly get out after popping them in, but hey, who really disassembles a super car nowadays, when it was nicely nailed into a transparent coffin mounted to a wall?

Which you can, in most cases, nicely tile-up. Even for reinforcing structures, when you tile cross-beam.

That's entirely subjective - and even if true, lego technic needed at least 40 years to get there. The first fully studless models were very skeletal and not at all particularly pleasing in terms of aesthetics and it took practically 15 years to create all the panel inventory to finally make them look more enclosed. Meanwhile models towards the end of the studded era were starting to look pretty good in their own right. I think the best models appearance-wise are ones that combine studless, studded and System - the 2007 motorized bulldozer is a great example of that. And today such models mostly exist outside the Technic line proper.

So all in all, I just don't think aesthetics was a factor here, more the fact that studless beams can be connected easier at the ends and stacked vertically, so they just lend themselves better for Technic construction. Still, studded beams have their place as well, as again - models such as the Motorized Bulldozer aptly prove

Yes, it is subjective that people prefer studless smooth models rather than studded designs with rough surfaces created from studded plates. But your view is subjective too. When I look at MOCs of vehicles, I think the majority of builders aim for studless designs and I assume this is because they are more aesthetically pleasing. 

But yes, it takes a while for a range to change aesthetics. It is highly unrealistic to expect them to develop a full range of panels in one go, but more realistic to expect a slower evolution as they determine what works in terms of design and what people will buy.

I don't understand your "fact" that studless beams are easier to connect at the ends, because studded beams can also be connected just as easily and can also be stacked vertically.

Although a lot of parts such as studded beams / technic bricks originated in Technic, I don't think of them as Technic only parts or that Technic is or should be completely separate or distanced from System. They have studs so they connect to System parts. There is no need for System and Technic to be separate. At the time they were introduced they had no use in System as the designs then were very simple studs up and relatively small. Plus of course, System as branding hasn't existed for 25 years or so.

[TeriXeri]

I noticed that too when I returned to LEGO, and sets from themes like Nexo Knights (2016-2018) had quite a lot of studded technic functions (and some studless too)

Even some basic gears and axle functions in Creator 3-in-1 fairground stuff and such.

Also in more recent years I noticed more of a trend toward clip/bar hinges over technic-pin connectors to connect sections/modules of sets.

You can't connect two studded beams at the ends with a 2L coupling, because their holes aren't close enough to each other. And if you do that with studded beams using plates, obviously they won't be able to rotate in relation to each other, as the connection is rigid. Even disregarding that and making a lateral connection with pins, the edges of studded beams are square rather than rounded, so you're severely restricted in being able to make them rotate against each other, and they can't do it at all if they're adjacent. Another thing is that you can't just use studded beams vertically without thinking, as the height of a Lego brick is a non-integer multiple of 1 stud tall. For that reason you need 2 plate spacers between studded bricks if you want their holes to line up vertically.

With studless beams none of that is a problem. You can connect them with pins entirely adjacent to each other, their ends are rounded so they can rotate into any position in regards to each other, and you can stack them vertically with no extra considerations, as they form a perfect square matrix.

So yes, aesthetics may be subjective but all these functions are definitely objective facts.

Absolutely true - however, with studless beams I need to take the thinking route you mentioned, when wanting to add studded parts, as that transition is also very often not trivial.

But hey, we are circling again: All studless has advantages, all studded has advantages. When mixing both: You get advantages to the power of two. As far as >I< am concerned. I am in the I don't care league, whether it is the one or the other.

I just do what I see fit using the entire LEGO parts universe.

Absolutely, same here. Those are my favorite kinds of builds. My only observation was that these kinds of builds have now migrated outside of the Technic brand, but they are definitely present - in varying proportions of the systems used.

[echos_myron]

Technic had been integrated with SYSTEM in the pre-dark times "adult" sets (Model Team and then early UCS SW, often for structural integrity reasons and for functions like vehicle steering). There's a huge uptick in its integration into child-targeted SYSTEM in the mid-00s; many sets from City, Fantasy Era, Aqua Raiders, 09 Pirates, basically all the post-dark ages revivals of earlier themes contain heavily integrated Technic features for their play functions. Now with the introduction of the O-clip, 3.18mm strength has improved to the point that you now see bars and clips replacing what Technic was often used for for the past two decades (good riddance, click hinges) as the 3.18 bar and clip system is smaller, more attractive, more easily integrated with studded parts owing to the sheer number of new clip and bar parts from recent years, and so on; that is now what you see holding panels on vehicles, making weird angles, and connecting sections of castles.

Panels Technic is its own beast and in my opinion worse off. To me the draw of Technic is knowing it's still LEGO, as Technic is obviously based off the same geometry, but once you lose any need to keep track of the 5/2 rule it just feels like a completely different construction system.

True that, and it was like that from the very beginning, when Technic debuted in 1977 (http://technicopedia.com/) and then of course in the 1980s line of educational sets (e.g. the LEGO Technic Control line-up). Technic seamlessly integrated with SYSTEM as - well - it was a system ...

Thank you! I have been a big fan of yours for years and always found you to be the "adult in the room" here.

And of course you are correct - I was specifically trying to think of when beams and pins and axles and the like began creeping into "non-technic" system sets before I (personally) began to run across far more technic part/function prevalence in kids' sets in the mid-late 00s. My first memories of that cross-pollination en masse, outside of pins connecting castles and the like, is Model Team, though that same start-of-MT era (late '80s) is about the beginning of my LEGO awareness, so there's likely more of that going on before then in sets I'm unaware of.

I think the beauty of it all is that indeed it is all the same system because of the underlying mathematics, so I don't like drawing the lines too firmly between system and technic (something I'm doing, not you). And is there anything more beautiful than a solid, mathematically sound Technic structure covered in plates and bricks? Maybe, but that's the beauty of being able to build however you like. :)

[Lyichir]

I love Technic but my preferences for sets tend to fall more in the fantasy/sci-fi realms, and Technic sees a fair bit of use (both structurally and functionally) in some of the "action themes" I like to collect. One of the standouts even over a decade later is Power Miners, in which pretty much every set had some sort of Technic-based action feature, but it's also used heavily in themes like Ninjago. Usually those sorts of sets tend to use Technic for things like transforming functions, moving weapons or traps, and so forth instead of common mechanical functions like faux engines, gearboxes, and transmissions, but it's still super satisfying to me.

[anothergol]

It's not just about aesthetics, Technic is for action, it's designed to bend to absorb shocks, where as studded LEGO will disassemble or break. 2 different uses, and you get the downsides of both when you mix both. 
And I know LEGO uses Technic a lot for structure in studded builds, but it's not always a good idea. If you want a large, static model that isn't gonna bend over time, you probably won't go Technic, or you will at least avoid technic pins (the real weak, designed to bend, point between technic frames that are otherwise pretty solid)

[dr_spock]

Friends sets are pretty good at combining stud and studless together for added functionality.

Hmm. Why would studded Technic beams/parts more easily fall apart when assembled with Technic pins than studless beams would?

Hmm 

well, what I usually do in any heavy-duty structure is connecting the beams with pins and then - as the Technic beams I use are mostly studded - attach plates over and under the joint section. This results in a very sturdy and hardly bending at all longer beam. Works quite well on my bridges, some of which are freely spanning more than two feet. Also on other machinery type builds, where bending would be detrimental. I don't have that much of shocks, as I don't do Technic cars. When it comes to shear forces or winding, bracing is the way to go. Bulky (2 plates on top, 2 on the bottom and a suitable Technic beam for bracing) but this is what heavy duty usually is. In this case, studless bracing beams are really nice, as the end holes are much closer to the end of the beams as in studded beams. And the looks is better as studless beams have no antistud sides 

In conclusion: It is the combination of the best of three worlds ...

All the best

What's the 5/2 rule?

I grew up with studded technic, had around 70% of the technic sets that were released between 1977 and 1991 (the older ones inherited from my brother, my own technic collection started with 8845 and 8030).

Therefore, everything felt easy and natural. It was no problem to learn all the basic rules and to develop new models and constructions.

However, I don't have this approach to studless technic. For me, in many cases it's confusing and not self-explaining.
it feels as if there are a million different types of connectors. And everytime I discover a new connector type, I investigate Bricklink, simply to find out that this part has been intoduced 10 years ago (or so).

Yes, the bigger studless models look great, but they often lack stability and rigidity. Quite obvious, because the missing studs mean that there are less crosslinks in the whole construction. 
Fun fact, if bigger non-technic sets need stabilizing skeletons, in many cases still the old studded beams are used instead of the new ones. Imho that says everything.

When made by TLG; competitors such as CaDA do provide much more rigidity for, e.g., their large cars. This may be due to them putting in more appropriate pieces for reinforcement, TLG usually economizes away.

The 5:2 (and 6:5) "rule" is often used, when snotting with System parts (see, e.g., here: https://bricknerd.com/home/snot-basics-geometry-techniques-and-pitfalls-3-18-2021). It does also apply to studded Technic construction, when bracing horizontal beam structures with (vertically aligned) Technic beams, studded or not. This is at least how I read it in the past. It is cool to read about it, but when you lived in studded Technic world for decades, you just do it without even knowing any 5:2 rule ...). Same for the famous "three feet = almost one meter rule" 

My general rule for bracing is: studded beam + 2 plates + studded beam + 1x4 Technic brick or 1x3 Technic beam at 90 degrees. And so on of course for heavy-duty stuff.

they wouldn't, it's what you put on the studs that would

so if those studs are to be avoided, well it leads to beams

Yes that's what LEGO does, but think of it,
whatever you attach with pins, even 2 or 3 of them on the other axis, will bend slightly, by design. The plates you attach to them though, can bend a little but they would most likely unstud themselves first. You'd then have to lock them on another axis using brackets, which is what LEGO does too. 
I've built the most solid frames out of 76766 brackets (which as a bonus cost nothing on BL, because for some reason no one likes them, or thinks of using them) sideways. They would break before bending, and not bend over time. (and yes they have technic holes so you may call them technic parts, and they're indeed locked using axles and round bricks)
Meanwhile some official SW UCS sets are known to have bent over time.

I remember when the "expert builder" system (later dubbed "Technic") was first introduced and when I first encountered studless beams and lift arms.  I never really saw studded Technic as "different" from "system" they were just more parts to achieve more specialized ends.  Studless Technic was more isolated, but I still found ways to incorporate both into my builds.  (and as a former educator, I'm actually quite happy when I see Technic elements (studded or not) sneaking in Friends and City sets because you just can't build with Technic and NOT learn at least a tiny bit about mechanics while at the same time, you're having so much fun that you don't realize you're learning about mechanics...)

So no, studded Technic hasn't gone away, but, having done complex (mostly studded) Technic sets from the 1990s and modern "non-technic, but using technic parts" sets today, I do think we've lost something.  That something is out-of-the-box complexity.  The high end studless Technic offerings can be wonderfully complex with complicated gear boxes, single motor-multi operational designs.  By comparison, City, Friends, etc offerings are using Technic, sometimes in visually grand ways (like the lift in the the Loop Roller Coaster), but mechanically speaking, most of these applications are very simple linkages. 

I think this (unfairly) suggests that studded Technic is the kid-friendly intro offering and that studless Technic is where the "serious" stuff happens.   Even Lego Education's own Spike robot kits echo this, the Spike Essential kit (3rd - 5th graders) features lesson plans built around system construction (and not even clever SNOT at that ) and the follow-on Spike Prime kits (6th - 8th graders) focus on studless.  These are artificial restrictions, the truth of the matter is that studless Technic has more choking hazards for little kids, that's really the only difference.

I can certainly understand TLG not wanting to load up a kit aimed at young kids with tiny parts, but when you get into the 12+ range anyway, it would be nice to see more complex use of Technic in non-Technic kits.  As for the Technic line itself, I pretty much expect it to be mostly studless construction these days, but when it comes down to the questions of nice parts usage and fidelity to the target model, I expect the official designers to be at least as creative (and flexible) as the AFOLs when it comes to finding the right part for the job at hand whether it has studs or not.

Hmmm. I am not convinced (which does not mean anything other than I am not convinced, breaking it simply down to only me).

Choking wise, you can swallow a lot of studded Technic pieces even today, particularly when mixed with studded System bricks and plates. Which is the entire world of studful Technic. 1xX plates, needed for the Technic "offset", are just one menu for the little kids. And yes, you can avoid them in educational sets, but it appears to be tough to go Technic in studful world without System parts.

Choking-wise, there are so many little pieces, little kids could try to swallow in studless world ...

Well, could be. Yes, gear boxes. But just assume, I don't like cars. Or gear boxes. I truly believe that "serious stuff" can be built with studful Technic. Really serious stuff. Whether it is more complex to do it studless - well, your choice. But first define "serious"; GBCs seem to be rather serious to me.

I am happily mixing all sorts of LEGO pieces - as I see fit. Whether this is serious - no idea. Is it Technic? I don't know. It is - for me - playing with LEGO pieces. But then: I am miserable when building studless. Could be my age, could be my don't want to be restricted, could be my lack of skills. All fine with me.

I entirely agree with you. That was one half of my point. "Serious stuff" CAN be done in studded Technic (and there are a number of great examples of this in official kits from the early 1990's).   What I think we've lost, however, with moving studded Technic to System themes and turning Technic into a (mostly) studless line of its own isn't the ability to realize complex designs in a MOC, but rather is official EXAMPLES of complex systems (like GBCs, great example BTW) being built from studded Technic.  The studded examples TLG choses to publish these days as all rather simple compared to what they offer in dedicated (studless) Technic kits.  I think this creates an unfair perception that studful Technic is less sophisticated/capable/serious.

For AFOLs, this is really just something we can have friendly (or at least civil) debates over, but for kids - especially those who don't realize the possibilities studful Technic offers - it implies a message of limitations.  I find that most unfortunate.

Maybe what we need is a new theme: Great Ball Contraptions, showcasing complex use of both studful and studless Technic tightly married to System parts.  TLG could made a range of kits in a range of price points ranging from simple ball pumps and ramps, to conveyer belts and scissor lifts, to screws and stair steppers and perhaps a flagship model or two of a robot arm or ball flinger/shooter.  A kid could learn a lot of engineering fundamentals from building GBCs (and seeing the potential both styles of Technic being used to maximum advantage ) and have a lot of fun in the process.
