How does one specify the center about which an object can be rotated?
I have obtained several objects as the result of separating what used to be a single
object into its constituent parts, and now I want to rotate one of those
parts (one of the new objects I obtained by way of the separation process).
My problem is that the center for rotation of the part is extremely inconvienient…
how can I change the center of rotation to make it reasonable (like the
barycenter of the vertices, for example), or, even better, how can I specify it
to be an arbitrary point?
Thanks
