"How does Tinkercad differ from Sketchup?"
-
I've wondered about that statement before -- is this a knock on SketchUps accuracy? (excuse my CAD ignorance).

Seems 123d (Offline) is some more powerful

Here's a Sketchup Render that shows the design better:

I think Backman referred to 3D printing - which is rather narrow but no problem for SketchUp.

Bonzai3d is also very powerful, and I've hear the term bandied about in regards to it as well... but I'm old school. I still have (and use) a drafting table, compass, french curves, t-square, triangles, templates, drafting pencil/leads and technical pens -- as far as I have been able to observe SketchUp is far and away more accurate than my traditional drafting tools (not that I do much drafting per se).

Bonzai hasn't improved their product in years. No updates

SketchUp not for designing physical objects?
I don't do anything but.

Yeah it's been about a year and a half, it looks like they have been putting all their effort into the newest formZ (which also contains bonzai completely) -- although I wasn't really saying anything in particular other than they have emphasized the "true CAD" element... which is a bit lost on me since I'm not clear exactly why I should care about that.

I did just that.
btw, notice how the title of the Tinkercad interview is "3-D Design for Idiots..."

Hey, that's a cool model, and a good one to show the subtle complexity of drawing on curved surfaces with Sketchup. Turned out nice, no?

It was really nice to handle the model - stainless steel - good weight and solid. First time I had something printed in metal. I made it really quick as a test so it's no hollowed out in an optimised way - just enough to keep the price reasonable. But the mode material the better it feel. I love it when the tactile experience is pleasing. I was drooling over titanium as well, but that was waaay to pricey. I got a whole lot more details than I had expected of the stainless steel, and I was lucky in how the grain was oriented in my model - I hadn't planned for that. I knew it'd be grain, but I didn't think of using it for surface texture. Eager to make more.

According to wikipedia:
@unknownuser said:
CAD refers to a specific type of drawing and modeling software application that:
- Is designed for creating technical drawings for distribution electronically and on paper
- Uses the accuracy inherent in a floating point, as opposed to fixed-point drawing database
Great, so I have some answers... does the SketchUp/Layout combo not meet these requirements?
Best,
Jason. -
meh… my images wouldn't attach in the comments section.. they uploaded and the post looked fine but they don't show in the actual post.. oh well..

Well someone in wikipedia-land is an idiot. Two reasons (limiting ourselves to this one clause)
- CAD could easily be done with scaled integer arithmetic on suitable machines. Like say using a 64bit integer where each increment represents one Angstrom (seems small enough to cope with important details. That would allow +/- 9 billion metres maximum range, which is plenty for anything up to a RingWorld.
- Floating point is not accurate; there are a mere 53 bits of significand, 1/1000th of the number (roughly, I used floating point maths here) in a 64bit integer.
If you want actual accuracy you need flexible length integers.
-
I work with single precision 32-bit floating point data all the time (audio) -- so I was not automatically thinking they were referring strictly to 64-bit... since many "true CAD" packages offer 32-bit versions as well.
Here is the wikipedia page I got the quote from: http://en.wikipedia.org/wiki/List_of_computer-aided_design_editors
Still, this does not answer the question of "why is SketchUp not a true CAD application?" Obviously the free version lacks Layout, which means it is not optimized for paper output -- but SketchUp Pro can create create technical drawings using Layout quite well. Aside from accurate arcs and circles I'm not sure where the perceived problem might be.
I think many people simply ignore the plugins when they talk about SketchUp -- which for me is a joke because I think SketchUp is virtually unusable without the plugins... whenever I teach I always point people to these forums and give them a full rundown on how to install plugins, because SketchUp is simply not complete without them.
I was helping a local landscape design specialist (a couple doors down from my office) get up to speed with SketchUp the other day -- they were getting bogged down in performance issues. As part of that conversation I made this statement: "The mistake most people make when first trying SketchUp is they think it is a complete program in itself. But it is really more like a platform -- you really need the plugins to make it worthwhile for much of anything".
They were coming from AutoCAD I think -- so I showed them how to make 2D face-me components, optimize component use and library, set up layers properly, optimize the viewport for navigation of heavy scenes, etc... But I felt the most important thing I did was give them directions here and showed them how to install and use a plugin (ThomThoms CleanUp).

Mr Backman is so 'off the mark' that I think very few will take what he is saying seriously. Now, if he studied SketchUp a little, which he obviously hasn't, he could have possibly made a case of sorts but as it stands, his blanket statement is for the 'birds'

I tried : very more difficult than SU!
And some less powerful!

...by any SketchUp user. But people with no experience keep hearing these statements and thinks SketchUp is not a serious tool Which is why you keep hearing comments like this.
