Use this procedure to change the overall dimensions of a ceiling grid. A ceiling grid is defined by its width and depth.
- Double-click the ceiling grid you want to change.
- Expand General, and expand Dimensions.
- Modify the values for X - Width or Y - Depth.
Tip: You can also change the size of a grid by dragging its grip points. Note that when you have a manual grid, you are dragging the individual lines, and not the grid.
