I just blathered on for a bit about this in one of the other forums. I will summarize here:
Rhino’s Display Modes offer an incredible opportunity that’s not really available in many other software packages. It could be argued that SketchUp’s display Styles are more advanced currently than Rhino’s but their dimensions and annotations are so primitive as to be useless. I’m working in Cinema right now which has an NPR engine that is world’s beyond Rhino’s Display Modes but Cinema can’t put a dimension on an object. Neither can Max or Maya or modo. Rhino can.
So - feature request. Imagine that Rhino had a very simple compositor, nothing fancy. Put all of your dimensions and text on one layer. Turn the dimension and text layer off and render everything else (whether as a Display Mode or with Neon, or whatever). Save. Then turn the dimensions and text layer on and everything else off and render. Save. Open the compositor and merge the two images with the dimensions layer above the rendering.
Yes, you can do this in photoshop and many other programs but being able to do this natively in Rhino would be a great feature. Send clients drawings of furniture or whatever you make with a handful of dimensions and text labels - all out of one package without having to save out files into another program, going back and forth.
