Hi, I am not too such about your comment but I understand your meaning. Now lets define the problem slightly differently. You have a list of xyz coordinate information for many points. First you plot these points onto the screen.

Datacursor is a tool which can recieve these xyz coordinates back by selection and write them to the screen in an information box. Therefore it must be possible to write a program to retrieve this information but store the information in a matrix instead of writing it to an information box. I think i did however see a slight rounding in the coordinate information when clicking on the screen using this function. I am not sure if you can get it to display "format long g" etc.

It could be that the program written will snap to the closest point where clicked on the screen this would be great. And disable the back points. this can be done with the actual depth information even though it is displayed in 2D? I hope this is clear.
What I really want to know is if Ginput can be used to retrieve points on a screen as i think what is needed is the reverse of Ginput. There must be an internal function that accesses the screen. If someone can explain that function it could be used directly?

Thank you.
