What if the grid of Maya's front view can't be displayed?

There are two places in the grid, one is the grid displayed in the comprehensive menu. One is the grid under Show in the menu in the upper right corner of this view. In maya, you can't see the grid in the perspective view, which means that the grid is hidden in the perspective view, or your perspective is too far away from the coordinate origin to see the grid.

Solution: first, display the grid in the perspective view. There is a grid under the display, so be sure to check it.

Second, create a small spherical object, which is at the coordinate origin by default. Select the sphere in the outline view and press the mouse shortcut f to maximize the display of the sphere. At this time, the visual center is at the origin.
