Sweep takes a group of up to 30 objects and places copies
rotated around a pivot point, step by step, in order to 
make an arc with as much smoothness as is possible.

---------------

Pivot:      select an object to act as the pivot point, then 
            click 'SET' on the pivot line. The object 
            coordinates will now be shown. Pivot coordinates
            can be replaced at any time, and will be 
            retained if the pivot object is deleted.

Objects:    select a group of objects to replicate, then 
            click 'SET' on the objects line. A count of the 
            objects will now be shown. Selected objects can 
            be replaced at any time, and will be retained if
            the layout objects are deleted.

Step:       set the size (amount of rotation) of each step 
            in the sweep. Shown as degrees, and as LYT 
            heading in brackets. Use +/- to 
            increase/decrease by 1, and ++/-- by 10.

Sweep:      place the next step of the sweep with the 
            'PLACE' button. The sweep number displayed will 
            increment with each placement, and can be 
            manually adjusted or reset uing the 
            -/+/RESET buttons below it. The direction of 
            the sweep can be toggled with the 'CW'/'CCW' 
            button. 

Reset All:  clears pivot and selected objects, resets 
            step to 1, sweep to 1, and direction to 
            clockwise.

Notes:
Objects that have already been placed (overlapping a 
complete circle, for instance) will be silently ignored.

If the original sweep objects have been deleted, they can 
be recreated precisely by placing once with the sweep number
set to 0.

If you need to hide the panel, use shift-B to hide all insim
buttons. The top right corner button will remain visible, 
and the panel can be reopened by clicking it.

Step and sweep can be changed during the sweep, but it is 
important to note how they interact: each placement is 
calculated from the orginal objects (in order to avoid 
accumulating rounding errors), and so are rotated by the 
amount shown by the step number multiplied by the sweep 
number. Changing one value mid-sweep will require changing
the other to compensate, in order to continue the sweep from
the same place. Another way to cope with this scenario is to
replace the original objects with the last placed objects, 
and resetting the sweep number - this will induce some 
rounding error, but it will usually be an insignificant
amount.
