Aligning organic shapes to top of circle

nAlyse,

As I (mis)understand it, you may wish to use the 1 step blend fake:

When you wish to have undistorted objects distributed along (part of) a circle (or another curved path which may be done similarly) and you know the number of objects, you may use the 1 step fake blend (for each set of objects if you have more sets to be distributed), with some preparation to make things fit together:

1) First place the objects on a straight horizontal line as they would be on a straight path, with a copy of the first object as the last object (only) if you wish to have the objects go all the way round the circle and meet itself; this is probably more or less what you have already;

2) With the centre Reference Point selected in the Transform palette use the X values of the first and last objects to establish the total width (which must be measured centre to centre) for the next steps;

3) Create the circle, copy it in front of itself if you wish to retain the actual circle behind the objects then lock/hide then original and work with the copy, then cut the circle where you want the centre of the first/last object and establish the total circumference (path length), you should be able to see it in the Document Info palette; for a full circle just cut at the start/stop (coinciding), for a partial circle cut in two places;

4) Adapt the size of the objects 1) or the circle 3) so that the width and the circumference (path length) become identical; you may use the Transform palette and multiply/divide the value in the W or H box by the quotient of the two lengths (just add * or / and then the number) and press Ctrl/CmdEnter to retain proportions;

5) Object>Blend>Options>Specified steps, set the value to 1 and set Orientation to Align to Path;

6) Select all the objects and Object>Blend>Make, create a copy just in case (now you have some distorted shapes between the objects, but not for long);

7) Select the Blend from 6) and the circle from 3) and Object>Blend>Replace Spine;

8) Object>Blend>Expand and Ungroup, and delete the distorted shapes, and you may also delete the copy of the first object (which is on top of it) if you have made one;

9) Enjoy.
