I saw in rhino 4 an yellow brep appeared when somthing is not properly mirrored
No, there’s no automatic command that will show you missing parts. How would it be possible for Rhino to know that something is missing?
I usually group children. For example, if I mirror something across the X and Y, my toolbar button looks like this:
! _Mirror Pause Copy=Yes YAxis
SelNone
Select SelPrev SelLast Enter
Mirror Pause XAxis
SelNone
Select SelPrev SelLast Enter
Group
In this case, it looks like you want to use ArrayPolar:
! _ArrayPolar Pause Pause Pause Enter Enter
Select SelPrev SelLast Enter
Group
If you want the parent to be excluded from the group, you can exclude SelPrev from the array polar command, but you’ll have to use _RemoveFromGroup at the end of the mirror command.
Sir i have done this with rhinoceros 4.in the above jpg.and the yellow brep appears.so how can you say that rhino has not the power to automatically highlight the not mirrored part?
I don’t remember v4 having that ability, nor do I know how it could have.
It would be great if you solve it if any chance,sir
