CarlB Posted March 14, 2009 Share Posted March 14, 2009 No way do do this in plain AutoCAD. Like your other request for creating TINs, this can be done using a survey software. The usual approach is to first use the contours to create a surface (such as via a TIN). It may be possible to create a lisp routine to interpolate a point elevation from the 2 enclosing contours but it would be quite an exercise and not as accurate as using a software package. Did you check out www.sitetopo.com, you may be able to create TIN's with this from contours. But still a leap to get points written to a grid.
