Change Z value of a block from text value

Hi,

I have a drawing with 1000 points (Z coordinate equals 0) and next to it, is located a text object. Is there any LISP that would take contents from text object and change point's Z coordinate to value from text, and iterate function for all the points?

Text object and point (actually an autocad block) have the same insertion coordinates.

The drawing is a flat map and I am willing to construct 3d mesh of a terrain.

I will be grateful for help.

Regards

Greg

PS Thinking about the problem even easier solution came to my mind. Changing Z coordinate of a text to it's value from contents and later making points in every text insertion point.

PS2 SOLVED. Data extraction does the trick. I export X and Y coordinate and Z from value. Next I import points by "Point Manager" by LeeMac.

How about creating a point at the text insertion with Z-coordinate set by the Text Content - or does the Text necessarily need to be moved?

Thanks LeeMac. Yes, that would do the trick too. Since I have solved it with data extraction there is no need in investigating more.

The interesting part started when I wanted to create 3dmesh from these points. Browsing through Cadtutor forum and Google I found several topics regarding this problem but noone could help with a LISP routine. Fortunately I managed to create beautiful solid with drape function build in Autocad 2011 - directly from points.
