I have created three cubes side by side. For dragging, I am using DragControls. But in front view, first of that cubes can’t be drag other cubes can be drag. Then I slightly rotate those objects using OrbitControls. Now all cubes can be drag. what will be the reason for this.
Interesting 
. Can you demonstrate this behavior with a live example? Unfortunately, I can’t image what’s going wrong…
Same object initially not able to drag. If I drag some other object before dragging the first object. then that first object also able to drag. what will be the issue
Sorry, but a video is not helpful in this case. I don’t think it’s possible to help you unless you demonstrate the issue (so it can be debugged).
