Array of points coodonates

Hello,

I would like to create an array of points coordinates, which are defined in the model sheet of DrafSight. After, this array of points will be tranfer to a text file.

1- How can I define points fastlly, with a simple mouse click? In fact, I inserted an image of an old plan of the nineteen century and I must define many points for modeling a surface.

2- How can I create the array of these points?

How can I tranfer the array to a text file?

Thanks for your help.
