Simple.

I will use a square matrix as an example below.

Use Notepad to open the sn06.des file in the sn06 folder, and press ctrl+f to search for Item09 (green beads), Item0901 (red), Item0902 (white), and Item0903 (blue) respectively. Every time you search for one, you will find a coordinate on it. For example, the coordinate of Iten0901 is Position: -834.097 752.100 -2.726. You can modify this coordinate. You don’t know how to check the coordinates? Enter Meteor, build a square array, enter the position command and it will be ok.
