How to delete gravity?

I built a desk, the surface of the desk isn't straight (it's bent inward a bit as if under a heavy weight). Now I have bunch of objects that I want to place on the desk, but since I'd take me forever to try to place them on the proper way I decided to use gravity to do the work for me.

So I selected the surface of the desk and assigned a passive rigid body. Then I selected the objects and assigned gravity to them. Then I created a keyframe on fr70 (when most of the objects stopped moving) and copy and pasted to the frame to frame one. Then went to the hierarchy editor and deleted the animation pegs. Problem solved!

Until today.. I tried to move some of the objects and I can't. In the channel editor Translate & Rotate info is colored green and Scale, Visibility & Blend Rigid Body is colored red. I know this has something to do with the gravity.. how can I remove it to be able to manipulate the object as before?

Also in my attribute editor for those meshes I have rigidBody,pariBlend,RigidSolver,PairBlend nods.

Thanks!

Select all the channels in your channel box, right click, and click "Break Connections".

Try that.

If you were just trying to drop them onto a flat surface, without random rotation and other stuff, you could probably have just used the align tool, assuming they were arranged properly in X and Z.

Thanks NextDesign that worked.

@stwert: Thanks for the suggestion. I didn't know about the align tool - had to google it. It won't work in my case (the surface isn't flat), but I'll probably use it in the future - I used vector snapping to align things, but this might be faster

Well that is easy. You just make the universal gravitational constant (G) zero.
