Hi,

 

I have a point on a 3D line's  exact alignment , although the Z value of the point is 0.

 

Can anyone help me with a lisp program to snap this point on the 3D line thus acquiring z value of the point. 

 

I have around 20000 points like this that need to be snapped and z value to be extracted.

 

Thanks in advance.
