Hi Mike!
I looked through all the topics on the forum, but did not find an answer.
Is there a function (option) or script or addon that can be used to manipulate object names?

When you have a lot of objects and some (or all) of them need to be renamed, it takes an awful lot of time. Alas ((

Blender has several different add-ons that allow you to perform group operations for renaming or prefixing / suffixing object names.

Maybe there is something similar for MOI3D?
