Dear TIG
Thank you for the suggestion.
May I humbly suggest that if the plugin could be coded to ....

1. "remember" the Groups/Components selected by the user
2. "remember" the splitting plane defined by 3 points by the user
3. then carry out by "repeating" the splitting action to the Groups/Components one by one?

I am totally ignorant in Ruby programming, hope you don't mind if I've a silly suggestion.

Regards

It would be a "10/10" slicing/splitting plugin , if it could be applied to multiple "solid" group or component at one time.
