Surface from points?

Recommended Posts

ravihotwok

Hi everyone,

 

I have some  points which I have created from a survey, the have individual x y z values, these are points relative to an area of land  have surveyed. If there a way using autocad 2020 to create a mesh or a surface to display this information and contours?  (hope that makes sense)

You can do this in Civil 3D, but as far as I know, you can't do it in plain Autocad unless someone has a custom lisp routine for this sort of thing?
