Hi list, I wonder if it is possible to draw "simplified schemas", such as those that can be found in biology publications where a protein complex is represented by a superimposition of ellipses, each ellipse representing a different protein in the complex, and their 2D placement reflects their known interactions in the complex (cf, for instance http://www.erasmusmc.nl/proteomics1/files/PBAP.jpg). This question triggered several interrogations : 1.) Is it possible in Chimera to draw 2D ellipses that would always reorient towards the screen as the scene rotates the same way the labels do 2.) Is it possible to draw ellipsoids ? 3.) Is it possible to save a picture in SVG format ? Thanks for your help, and thanks once more for the wonderful tool you provide us --Ben
