Hi hyeokjuSa

If need just change axis center, then double click on any spot and the widget will be “moved” to the new position. If want change CENTER of the model then you need move it so the GRID PLANE center adn the GRID PLANE center will be the center of the model (0,0,0 )

i want to define the axis(0,0,0) center of the model(foot).

i don’t know how to move the GRID PLANE … :?
