not sure if I completely understood your question.

you can rotate around the origin of the current cplane with
_selNone _rotate _pause 0
maybe also check
_arrayPolar
with the step Angle option

if you use those fancy numbers like 40.8631
make sure your display precision (options - units - …)
is one digit more - in this case at least 0.00001
it s not well documented if rhino will remember all digits in the background. And I somehow remember some issues with the loose of some digits (but it was about fillet or filletCorners)

does this help ?

kind regards -tom

Thanks.But i want to autoselect the last rotated object and from there i want the previous distance to rotate the next.such as copy …
copy

still not 100% what you re after.
your screenshot shows the _move command ?!
you can

_selLast

to get the last created object.

but for me it still looks like you get what you re after with
_arrayPolar
and Number = 3, stepangle = 40.8631

what do you mean with this.
moving will use a distance
rotation will use an angle.

where exactly meassure those 40.8631 ?

Sorry.I confused you without knowing.Thanks for your time.Step angle is my answer.Now i want
a macro of array polar with step angle[as you wish]and “0”_Enter.

for always 3 objects:
_selNone _arrayPolar _pause 0 3 _stepAngle

for different number of objects
_selNone _arrayPolar _pause 0 _pause _stepAngle

above approach will skip preselection (_selnone).
if you want the macro to work (only) with preselection, skip the _selNone and the first _pause.

I do not know any approach that allows for a macro to work with both workflows - (pre) selection - command And command - (post (?)) selection. Do you @Gijs ?

Thanks a lot for your help.

I think your macro without the _Selnone seems to work in both cases

ok, great.
seams like a _pause is skipped if it stands for object selection…
hm :roll_eyes:

_move _pause 0 r10,10,0 - works for both, pre / post selection
_move 0 r10,10,0 - only works for pre selection

would be nice to document this, maybe here and give the advice, to develop macros with post-selection - that will (is that true ?) always (?) work with pre-selection.

thanks - kind regards - tom
