Hello, I am working on developing a new suite of flexible multimedia 3D printed protein models using Chimera to process to .stl. I am trying to make a sort of “anatomical” cutaway of an enzyme complex where I can slice the model in chimera along a certain plane and print the sections with caps, but am running into problems. I have tried simply clipping into the model, which does essentially what I would like to do, but I don’t know how to delete everything that I’ve clipped out of the model. When I export my scene, it still exports the whole model instead of the clipped depiction. Ideally, I would like to just cut the pdb in half to start with more advanced cutaways coming later. Do you have any idea how this might be accomplished? Thank you!
