Sketchup is Inacurrate???

circles are not supposed to be equal and they must intersect.
well show me your files.oh.. i didn't get the part about unequal circles.. so all the results discussed so far look something like this
edit-- and we can't do 3 unequal circles in sketchup without using a plugin or a hack i'm not too fond of..
and even then, we'll only get true results in certain cases.. (and i might be saying some of this too soon without thinking it all the way through.. but feel free to prove me wrong

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.

right gilles.. i was just ribbing you on the last page even though i knew what you were getting..
that ability is sorely missed in SU
a few times i've seen the idea of construction circles being in sketchup which would be great to have as well. -

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?

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.

It has been a long time we were asking for fix in sketchup with poor replies.I would recommend Rhino; for precision and for architecture.

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. -

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
