I made a model of a few books in a simple case with a turned rail in front.(image on left) The case was made with duplicated primitive cubes. The rail turnings were a replicated array. When I group all and copy to a new document (or export as a carrara model) I get the result on the right. All my geometry has collapsed to the primitive level. Anyone know how to copy my model to a new file? This seems to be a new bug in C4, at least I didn't ever run across the problem in earlier versions. Thanks, Ed

This is a long shot, but I'd check the scrubber on the time line. If it's off the Zero mark things might be reverting to an earlier state.

Well I'll be! You're right! This is interesting as I have never even pulled up that tray. Only ever did one animation about a year ago. So is there a way around this so I don't lose my admittedly minimal modeling? Thanks, Ed

Look for keyframes that aren't supposed to be there and delete them?

Update: I tried deleting keyframes and more and finally settled on disabling "Animated" in each objects properties, then running the time back to 0. Most things stayed the same so my copy and paste was successful. Thanks for helping me sort it out.

You deleted "Animated" in the properties? Clever. In cases like this, when I've got too much effort involved to throw the model away, I just started the animation at the earliest point in time at which the model is not distorted. Instead of an animation that runs from Frame 0 to Frame 200, I'd have one that runs from [let us say] Frame 45 to Frame 245. Deleting keyframes never worked. Duplicating them and moving them back didn't either. You just have to ignore anything prior.

Interesting didn't know that disabling animated would do that.
