I work on 2D elements on the same story as my co-worker. I work on one corner of the plan and the co-worker works on another corner. It seems like I cannot reserve the 2D elements because my worker is also working on the same 2D elements as I do, like lines, fill, and text... if you know, please show me how to reserve it properly.
Thank you
