Dear all, I'm in the process of 3d printing a large protein in ribbon format; I've generated the .stl file, but the resolution of the mesh that Chimera creates means that the resulting file is too large to use easily. I've managed to use other software to reduce the resolution of the mesh, so I /can/ now get around the problem, but can anyone tell me if it's possible to reduce the resolution of the mesh in Chimera to save me a step for future models? I know how to reduce the resolution of a surface mesh, but files of ribbon representations remain obstinately large. One method I've used that gives limited results is to simplify the cross-sectional form of the ribbon, but I wonder, am I missing something obvious and more effective? thanks! Gavin
