<html><head><meta http-equiv="Content-Type" content="text/html charset=utf-8"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class="">Hi Oliver,<div class=""><br class=""></div><div class=""> One more step you probably want when showing clip plane positions in a side view is to use orthographic projection (command “set projection orthographic”, then to get back “set projection perspective”). The Chimera side view dialog uses orthographic projection. This makes the image projected exactly perpendicular to the screen so that the clip line really is the dividing line between what is and what is not clipped.</div><div class=""><br class=""></div><div class=""> I’m curious what kind of image you will composite from the two side images, one with per-model clip planes and one without clip planes. Will you fade out the clipped away part (the unclipped image) then overlay the two? Then draw in clip lines in a paint program? In Chimera I think it would be pretty easy to make a shortcut that replaces near/far clip planes with per-model clip planes, adds two rectangular slabs, animates a rotation by 90 degees to show an edge on view, then unclips so you can see the models outside the clip planes, with rectangular slabs now viewed edge-on to show the boundary between clipped and unclipped. Then the same shortcut could reverse all those steps to get you back to the original view. In ChimeraX we could be even fancier and have the part outside the clip planes be faded.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>Tom</div><div class=""><br class=""></div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Apr 27, 2016, at 10:25 AM, Oliver Clarke wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class=""><div class=""><div class=""><div class=""><div class=""><div class=""><div class=""><div class=""><div class=""><div class="">Hi Elaine, actually this works pretty well, thanks!

The closest thing I can think of is that the per-model clipping command has an option to put the front and back of the slab at the hither and yon planes. It’s “mclip” command with option “match nearfar” … but as you said, it is cumbersome to repeat for multiple models before turning everything 90 degrees.<br class="">
