I have a set of 3D points plotted in a scattered mode, is there anyway to interactively select a subset of this point cloud and save it to the workspace? (without using brush; because I can't get it to work).

The goal is to to ask the user to select a subset of the scatter plot and save the x, y, z values of the selection.

Any help is much appreciated.

Brush does the job, except ... requires assigning a name to the saved the data, and [that] makes it way difficult to use the saved data in a loop with random names)."

I've never used brush so am totally unfamiliar with its syntax/requirements, sorry.

Could you present the user with a selection tool that gives a choice of a variable name and then use it? That should let you handle the problem if so.

As said, I don't do GUIs to any extent as was fortunate to able to hand that task off to folks who really knew how to do so...hence, I'm just guessing here, sorry.

Hopefully somebody else who does know something about it will come along, too...
