This isn’t a forum where we do your work for you. Topics with phrases like “who help me” is going to make sure no one will do anything for you now or in the future. No one likes to be taken advantage of and you are not paying us. Show some effort so that we can think you are actually trying to do the work before asking for help.
Please read this post before asking for help in the future: How to get help on the Dynamo forums
Edit: For context, the original title was “Create two point from grids created in revit. who help me?”
please provide a sketch as it isn’t clear what you are after
