How to get brushed data into a variable programmatically?

I have a 3D plot. I want to select a region from it and discard the rest x,y,z points. I want to use the brush tool to select the points that i need and save them in a variable using commands. I have seen some posts regarding this issue but still the problem persists. Any help is appreciated. Thanks!

You can use the 'BrushData' property to get the data into a variable as mentioned in the answers link
You can get only x,y points with 'BrushData' and you can use 'find' to find the indices of the brush data.
>> z = peaks(25);
>> figure
>> h = mesh(z);
>> data = h.BrushData;
>> indices = find(data);

Is there a way to get z points as well? Because i have a 3D plot.

I'm having troubles with the same problem. I know the question is really old, but, did you find any solution?
