Hi Dave, If you just want to fill rings, use the "fillring" command: <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/fillring.html> or you can create arbitrary polygons with BILD format: <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/bild.html> The reason to use planes from Axes/Planes/Centroids is that they are "smart" objects that can be used in distance and angle measurements with atoms, axes, and centroids, as alluded to in my other replies today. If display is all you are concerned with, either of these other methods will suffice. In Thermal Ellipsoids, the probability is working fine for me. You enter a number in the probability area and press return, which will accordingly adjust the number shown in the "Scale factor" field. Then that scale factor will be used the next time you click "Show Ellipsoids" or choose one of the Thermal Ellipsoid presets. <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/thermal/thermal.htm...

Hi! Thanks so much for adding the define plane and define centroid features. Is there any way to add the option of defining the border of the plane as a polygon where the selected atoms define the polygon vertices? This would allow a plane in the shape of a hexagon or any other heterocycle to be inset inside of an aromatic ring for example without the edges of the plane being visible outside the bond enclosed area. Also, the thermal ellipsoid feature looks fantastic, however the probability setting doesn't seem to be functioning.
Thanks again for adding all these features, Dave
