Make surface from 3d points!

[Margusrebase]

Hi,

 

Is it possible to great autolisp that can make 3d surface from 3d points?

 

All the best,

Margus

Do you need a 3DFACE or a 3DSOLID ?

3DMAX handled it this way via 3DSOUT 3DSIN

 

(entmake 
 (list 
   (cons 0 "3DFACE")
   (cons 10 pt1)
   (cons 11 pt2)
   (cons 12 pt3)
