[chimerax-users] Volume eraser as cube?

Hi all, Hope the chimeraX team & community are having a great start to 2025! There are often situations (in single particle cryo-EM) where I would like to erase using a plane rather than a sphere - e.g., when I want to chop off density protruding from a nanodisc or micelle in order to make a mask. There are various workaround ways to do this (e.g. just making the sphere enormous, making a cubic/rectangular mask and multiplying/substracting, etc), but I was wondering if this is a common enough scenario (perhaps other users can chime in?) that it might be worth adding the option of erasing using a cube rather than a sphere? Cheers Oli
