    Hi pranav_suresh7, thanks for tagging me! The delegate is not supposed to be called right after it is placed. Could you share a video of what you're experiencing, including any logs? Could you also share your delegate code here? 

    To tell if or when the object is currently being grabbed, use an Interactable Group View component and set its Interactables list to all of the grab enable interactables (hand grab, grab or ray).

      Hi Big_Flex  thanks for the reply.  this is the issue https://youtu.be/zl_rwHjp-Ew. I got where the issue is coming  but I don't know which is the proper way to resolve this. In SnapInteractable-> SelectingInteractorAdded-> SnapElement function I'm marking the added Interactor position in gird as MARKED, in the DoSelectUpdate() function in SnapInteractor which calls the function (Interactable.PoseForInteractor(this, out Pose targetPose)) that calculates the position/pose for this SnapInteractor. So this function Interactable.PoseForInteractor(this, out Pose targetPose) is also called after SnapElement function where I mark the position as MARKED. Since here Interactable.PoseForInteractor(this, out Pose targetPose) if the position SnapInteractor matches this MARKED position it returns FALSE since it was already marked which makes _shouldUnselect to TRUE. I can fix this by adding some conditions but I don't know whether that is the right way. PROBLEM: I have a grid of positions, when I place the gamoebject on to grid positions I have to attach the gameobject to respective positions. If some position is marked as ALREADY ADDED  then I shouldn't attacht the gameobject towards that position. Also after it reaches the position it's size have to change accordingly with the position where it's attached.
