Cura Dual Color - Requires CSG difference first?

[cyclone 0]

The first dual print posted from UM, the Robot in the Crystal print, made it appear that you could take two solid models and dual print merge them and cura would print them overlapping but separate colors.

It appears that two solid models results in the overlap being printed in both colors. Is this intended? I would expect that Cura would delete the overlapping gcode from one of the colors so there isn't a problem extruding plastic were other (color) plastic has been lain.

Is this how it does, in fact, work?

Is there a way to have Cura pick one or the other color and discard the overlapping other color?

I ask because I have a complex model that Blender and OpenSCAD have trouble CSG differencing.

Thanks

Currently, Cura does not do this CSG difference for you. I actually have the code for it in place, but I disabled it.

(Some overlap can actually be useful from time to time, as it generates different bonds and the bonding is stronger where there is overlap)
