How to measure grid size

hi

I create grid 8x8 and attach to node , i would like to how can i measure for grid size

Not sure but i think a grid cell is 1x1 world unit, so your grid would be 8x8 world units.

I think you can have confirmation of that by looking at the Grid class code.

You can get its world bound and get the X, Y and Z extents from there

Thank all for reply me.
