Thanks a lot Elaine, I'll have a look at these.

@François, I am more skilled with inkscape ;)
And yes, since Chimera doesn't produce SVG, my idea is to produce pictures of each simplified elements of the complex with chimera, then to import separately the bitmaps of each elements in inkscape and rebuild the picture in an SVG format that way :)
