What is keeping the translate arrows from working on the 3D Manipulator Tool I can't figure out why my translate arrows are no longer working. If I use the tool bar or the hot keys I can get the rotate and scale to work as I would expect, but I can not get translate to do anything. It was working in a previous save, so I went back and compared and couldn't figure out any differences. I then proceeded with the old file and it stopped working again. Anyone have any thoughts? I tried changing the system ->selection to OpenGL Select as I found in one forum without luck. I haven't been able to get anything else to work. I've uploaded the file to my google drive if anyone would be kind enough to let me know why this super frustrating thing keeps happening. I'm assuming a setting keeps getting toggle on/off or something similar, but can't figure it out for the life of me.

Thank you so much for your help,

Snap to Grid is enabled (and the object is smaller than the grid)

The selection can be moved, you are just not providing an input that would be able to overcome the thereshold of the snap to increments.

If your object would have been 10 time bigger, you would now experiencing a stepping in using the grab tool, but as it's dimensions are small, you are not able to jump over the first step.

The solution would be to disable the "Snap suring transform" option.
