Grab mode problem(Moving in 1 unit blender)

Hi. I’m new to this forum and also to Blender here. I would like to ask a question. I am modelling a small plane with Blender started a few days ago. Until a point where I model, the grab mode movements changed itself to 1 unit blender minimum. I can’t make it move smoothly at any other vertices. I started another blank workspace with a cube and tried to move the vertices and it works just fine. I hope there’s someone can help me on this. I’m not sure if I pressed anything wrong while I was modelling it. :confused:

Here are the pictures of what happened to me :frowning:

Please help and Thank you very much~

Sounds like you have snapping on set to increment.
On the right side of the 3d view header is a magnet icon which turns on/off snapping.

OMG!! It worked! Thank you very very much!! Thanks Richard~ :slight_smile:
