Hello all, I feel as though I'm being hard of thinking here. Here's a PG: http://www.babylonjs-playground.com/#3ENM44#1 How do I make any one of the boxes stop moving when it hits another? I have got as far as it logging to the console when the ellipsoids collide - not what i want though. This needs to be accurate to .001 scene units (a millimetre for my setup). Think I'm going about this the wrong way. Importantly, I need to get this working with the gizmo. Any help would be much appreciated. Thank you.

Hey all, I'm looking for some direction on snapping objects into position against other objects edges. I'm also looking to define a snap point on an object and use that to lock it into another objects corresponding point. The first problem is essentially voxel drawing with irregular sized objects (all prisms), I need to be able to click on a face and have the new object placed in relation to the face that I clicked. So if I cast a ray and it finds the top face of an object, the new objects bottom face should align with it. (and snap to whichever side edge the mouse was closer to?) I imagine the second problem as having a little sphere attached to the objects mesh in an arbitrary location, and using that spheres center point to snap into the nearest objects corresponding anchor point. Like defining a hook on an object and using it to snap onto a clothesline. The Babylon.js API is pretty huge and I'm not at all familiar with it, but I have a reasonable grasp of the concepts involved. Any direction or suggestions on how to make a system as I described work would be greatly appreciated.
