Sketchup is Inacurrate???

in fact , what I was pointing is that you cannot draw accurate or precise with circle or arc tool, like bisector tangent etc... all things I learnt to draw by hand long time ago which is called geometry.
You can get somewhat close with the arch tool, since it shows a tangent continuation. But of course far from accurate not only because of the segmentation.
So I still wonder if someone could write a compass plug in for Sketchup? To create circular construction lines?
Or is that just a nice fantasy?

a few times i've seen the idea of construction circles being in sketchup which would be great to have as well.
That is the reason I am looking to Rhino, Bonzai and Moi.
At this point I really need to draw accurately.
It has been a long time we were asking for fix in sketchup with poor replies.

The real question is why people like Tig, Thomthom, Fredo,and and and and ............... are able to create missing basic tools while Sketchup Team does not?
Aren't they paid for? -
I would recommend Moi; for precision and for SU spirite ergonomy!
And its true gem helper lines system!
And only pen graphic if you want! (mouse, space Pilot authorized
And the direct contact with the author!
And free direct plugins if reasonable time making!
And for the beautiful drawing itself on the screen work!
And best mesher Nurbs --> OBJ : price ? (2.5 / Rhino)
By Paq must be zoomed of course

Three different sized circles touching tangentially. Radii of 12', 9' and 6', giving center to center distances of 21', 18' and 15', all done in SU using only native tools. Do I get a cigar?

Looks good but not good enough for a cigar my friend. the corners don't touch and there are two gaps ...

Well of course they don't touch...they're not bezier curves, they are polygon approximations of circles. SU still understands them as circles with those properties...and if you increase the number of segments (to say 120) to get rid of the facets, then the edges will touch.
Criticizing SU for not displaying true curves is like criticizing and Abrams tank for not being able to do aerobatics. The right tool for the right job. -

right.. that's what i was saying earlier.. there are only a few actual cases, regardless of method (plugin/calculator/hack), where all of this geometry can come together properly in sketchup

alan,
i'm a big fan of that saying as well.. (and apply it in my own stuff)• but is this or is this not an architectural modeler?
• are circles and arcs not very basic design elements in architecture? (i mean sketchup has straight lines and does good with those.. what's the next basic building block? an arc.. as in, the arc is the second most basic thing you use to draw with)- so is sketchup good for architecture?

Aren't they paid for?One of the pressing questions about Sketchup is, is it really that intuitive and easy to use once you leave the simple square?
Edit: and even the simplest of pitched roofs become an instant challenge without the help of those people like Tig, Thomthom, Fredo,and and ....

I'll tell you with a we bit more sophisticated options it absolutely would be.
As I said before some issues just need to be fixed. And there is no reason why not. -
@gilles said:
Just a basic, try to draw 3 tangent circles with native tools and tell me how much time you spend.
Of course they must intersect.
added a 4th into the mix in under 12 seconds..

As I said before some issues just need to be fixed. And there is no reason why not.But you said those circles weren't accurate...and they are. They are circles of an established radius and they are the correct distance apart for their circumferences to touch tangentially. Whether they actually touch visually is entirely dependent on how many segments you care to assign to them. Did you increase the number and see that they do, in fact, touch?
SketchUp could certainly do with more options to construct circles and arcs starting from various points along the curve. I believe ther is a plugin that will do that (which I don't possess)...but that is a question of usability, not accuracy.I'm not an architect, but there appear to be an ever-growing number that believe it is the right tool for the job. Maybe not the only one, but certainly one that has radically affected their workflow.
As for your question of whether it is still easy once you get beyond rectilinear shapes; well, as I routinely use it for modelling eveything from tufted sofas, through all manner of organically shaped furnishings to entire human figures and trees, I guess I'd have to say "Yes it is."
That's not to say it can't be frustrating at times; and there are certainly some processes that are much easier in other programs. But taking the broad view, it is still much faster and easier than anything else out there. If it wasn't, I wouldn't be using it. -
8 seconds with Moi but with a little training!
As right click repeat the last function it's some easy
Ps All circles are different

If it wasn't, I wouldn't be using it.They may be accurate in a way, but in the sketchup world they need to touch or intersect.
Because those small gaps will cause a problem down the road.
And in my experience there is no speed gain with inaccurate geometry, only long hours of fixing and finding those minute little gaps. I tell this my guys who build models for me and I'm very strict about it, models created with sketchup need to be water tight. No gaps, no just a wee bit off.I used to work with AutoCAD and 3D Max for Arch Vis, Sketchup has sped up my work flow.
Don't get me wrong, I won't compare these programs.
All I'm asking for is to fix some bugs that have been around from the beginning of "sketchup time" and as I said before, just a few fixed will make SU an outstanding tool. And I do not understand why anyone would be opposed to this notion.
Also I would vote for a constraint override.
The inference engine is one of the most limiting aspects of Sketchup. It is convenient for square geometries, but strongly impairs tasks like tracing and any 3D geometry that is not square.
I'm sure it would not be that easy building organic geometries using only native Sketchup tools ... -

i'll give you that
i mean, you're right, if the circles in your model are infact accurate (proper radius.. proper x/y centerpoint) then i think that's an acceptable and useable result in sketchup (due to it's inherent nature.. its polys)..for posterity sake, i think adding a cpoint at the exact tangent points would be nice.
[because once you have that cpoint, you can then fill in the arcs completely and accurately.. which, to me, is definitely an acceptable tradeoff for us using segmented arcs in the first place )
i also think we should have solutions such as this from within sketchup.. it's really not much to ask and it's not a bloat alert.. i mean so what- some apps do require more tools.. put them in there.i know tig has true tangents.. and it's great and i congratulate him (i think thats when i dropped a donation his way if that matters).. but the user experience is just not there.. its more
than 
these types of things need to work quick and straight to the point.. for the most part, it's the power users* that will be taking advantage of these plugs so tailor the experience to their needs.. i mean, that's your target audience..
if this stuff was inside sketchup's own UI, there would be a consistency.. you might: :tangent circle: and it all flows.. but now, it's stop and tinker.. and, maybe, tinker some more..
so in that regard, sketchup could have a sort of ruby control [thing] which the devs can plug in to for things like interface and dialog.. with a simple set of (suggested) guidelines to adhere to.. as now, you have a boat load of rubies out there and none of them really act the same.. and it's far too rare when you'll see topics of "hey, let's nerd out and talk about how this is really working out from the user point of view"
seriously, if you guys (suteam) do not want to do the stuff requested in this thread to your app.. that's ok.. hook these boys up with some more ruby access.. set them up with a little vending machine.. there are obviously people that are willing and able to make workarounds.. but often it comes out as "whelp.. here goes another workaround".. but with the right developer access, and an ideal of more uniformity, they can make truly legit workarounds.. to where it doesn't feel the slightest bit workaroundy..
thank you*[EDIT] -- please, no one tell solo pete someone actually just called themselves a power user and they use macs

thank youMaybe those SU dev's should consider hiring or at least inviting those "ruby wizzes" into their holy grounds along with some Pro Users that work for the money as a kind of conference. Closed doors for 2 weeks hard work to get this thing together.
