Hi Damien, I cannot reproduce this problem -- per-model clipping works fine for me here, both on my desktop Mac and on a Windows 7 box in the lab. Please do this: save a session just before you would turn on clipping and then use "Help->Report A Bug" to file a bug report and attach the session. That will help us debug this. --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu On Apr 27, 2012, at 1:23 AM, Damien Larivière wrote:

Dear all,

I try to use the Per-Model clipping tool but this error is returned, whatever the PDB file: Model cannot currently be clipped [no valid bounding box]

Do I make something wrong?

I use Chimera version 1.6.1 (build 35849). My configuration is Windows 7 64bits, ATI Mobility Radeon HD5650.

Many thanks for your help!

Damien
