Hi shokan22
Just draw 2 circles. The smallest in the center and the larger outside in the position you want. Then use the blend tool select one of the circles and point to the other. Specify the number of intermediary steps (circles) you want (in the context toolbar on top) and that's it.
Thanks, but because the smaller circle is not placed in exact center of the larger, I am not getting equal spacing. How do I get the perfect centering of the smaller circle in the beginning? Also, what's that radial line segment that appears?Quote:

The perpendicular line you see is just to show you that the circles were created with a blend (from the first circle - the inner one to the other. It will act as a single object while it´s a blend. If you need to separate the circles so they become independent, select the blend go to the menu Arrange->Convert to Editable Shapes. This will convert the blend to a group of circles. Then go to Arrange->Ungroup to get the circles ungrouped.
Excellent, thanks.
You could also use alignment from the arrange drop down. Select both and align both vertical and horizontal to align centrally.
Always a few ways to skin a cat. Use the Contour Tool for drawing this very easily. See attachement for instructions.
Bob.
:) thank you for the solution... i was also searching about this...
I kept pointing to the other circle and nothing happened haha. So I looked up in the help and saw the word 'drag' or similar holding down the left mouse from one circle to the other. That auto made 5 steps, which could be increased, then I could play with the other effects.Quote:

This works, for me, in quite a different way, as I created 2 circles, applying the contour, the menu did not auto appear at the top. When I finally did get an affect, the 2 circles result seemed to act, how can I say this so it makes sense in text, together but independently. The inner circle kept the sense of multiple concentric circles as size was increase/decreased above 50%, while the outer circle remained solid upto 90% [% relates to the slider] (as though I was increasing the outline size - if that makes sense). I know I've done something wrong so I'll try and go back and start again.Quote:

Attached original 2 circles at 50/75/90%

With contour, I am finding that you must begin with a small initial circle (or you get left with a large blank/open space in the middle, that you only need one circle (more and the above posts effects occur), and expanding the contoured tool circle is restricted, at least more so that in blend mode (blend . Also finding some other strange effect results, which might be useful, but in coming up with 50 equally concentric circles as per the OP's post, blending seems to produce the best result IMHO.
If I'm doing something wrong, please correct me - thanks.
In this particular case, although it can be done with either Blend or Contour tools I'd recommend the blend tool as it's far more configurable.

@ Egg
The video comes up with "Sorry, this is private"
Sorry puw, for some reason my YouTube channel is defaulting to Private instead of Public. I keep forgetting to alter this. I've made it Public now so you should be able to view it.
Hi egg, yes I can watch it now thank you very much (also just had to update my flashplayer).
WOW. That is a great tutorial video on this topic (for all shapes), because the moving it around, quickly allows you to do perspective with it. I did not know that move - thank you.
A quick question - did you remove the first small circle, or did you just select it via ctrl left mouse, in order to open the ability to move it around? I only ask as your mouse movement in the video (not your fault) made me think you were selecting it to remove it. Seems a silly question as I read this back, but just wanted to be sure :)
I'm just wondering, this idea popped into my head, that if you did the concentrics, moved them for perspective, then created all semi-circles, would this be possible do you think? I'm thinking this would really help and save time in constructing an arched enclosed walkway or internal view of a cathedrals roof (for example), as the framework to build on. Your moving it around is giving me quite a few ideas (James Bond film intro).
Selected the small circle by Ctrl+Left Mouse Button then moved it about. I tend to use Ctrl+Alt for this as once selected and as long as you keep the left mouse button depressed, you can move it about at will ~ great if you've many small close spaced objects.
Something like this?
We had a good discussion re James Bond film intro HERE a couple of months ago.
Yes, that's exactly the kind of thing I was visualising Egg.
Wow, it works, really good - thanks.
Since you've shown it can be done, the arched corridor using this effect, I'll go and try and do it. Thank you :)
Ok, so I made a blend, put some perspective on it and then went through the process of selecting each circle and making each into a semi-circle (as discussed here http://www.talkgraphics.com/showthre...582#post518582 )
This is just to begin, to see if I can work out how to do. I tried selecting all, convert to editable shapes, but the nodes don't show for each one, so I realised 'you must' do each one individually (don't know of a quicker/easier way).
End result was a vary basic arched corridor (looks more like one of those long greenhouses for mass production lol) - so initial success :)
Then I wondered if I could alter the perspective, so select the smallest arch, ctrl alt and you just move the one arch. So, managing to select all, the ctrl alt trick does move them all, but not in the same manner which I am guessing is due to making them all editable shapes - the arches become in effect a glued rigid structure.
So the key to this is making sure you position your concentric circles perspective correctly before converting and cutting them up!
Another plus for me in doing this exercise, is that I am beginning to understand perspective a little better, and when I see 'blind spots' mentioned, I'm starting to grasp what you all mean :)
If you have Designer Pr, you could use the Blend tool to keep a rigid shape.
The start and end objects are Ctrl selectable.

The rigid structure reference is with regards the difference of after selecting the original circle/shape, then ctrl alt with 'left ' mouse on, and moving around is quite flexible, to cutting up the circles and losing that flexibility (becoming rigid in the movement). I was hoping to keep the flexibility.
Not following you here puw. When are you cutting up the circles? You should do it first then use the blend tool.
Ahhhhhh, "I see," said the blind man - lol.
I was getting the perspective first, then cutting it up. Did not even enter my brain that if I cut up first, I could blend the arches and then have full flow of perspective (that is the ctrl alt and left mouse held down to move wherever).
I shall reverse my process and try that out Egg. Thanks for the heads up :)
Think I need to get a new perspective myself so I can see through your eyes m8 !!!
