Hello Mohan, If you read the Help for Volume Eraser (press the Help button on the dialog to see it), it explains how to move and resize the eraser sphere. Or, you can see this information on our website: <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/voleraser/volerase...> Basically you can set which mouse button will be used to move the sphere, and then use the mouse to move it to where you want, including with Shift to move in Z (toward or away from you). There isn’t a feature to automatically put it at the center of the capsid. For user questions, the better address is chimera-users@cgl.ucsf.edu (not this address chimera-dev, which is more for programming questions). I hope this helps, Elaine ---------- Elaine C.

Hello,
My name is Mohan Sudabattula, I am fairly new at using Chimera so please excuse my lack of understanding the program.
I am currently utilizing the Volume Eraser tool and am trying to employ it erase the internal structure of a viral capsid. Upon opening the Volume Eraser it always seems to orient itself to the "frontmost face of the current display region". This is problematic because it is now only partially erasing what I am needing to be erased.
Instead I am looking to have it oriented so that it is in the center of my virus. Is there any way to reorient the eraser so that this may be the case?
Thank you! Mohan Sudabattula
