LISP for prestressed concrete

[saptonja]

Hi everyone,

I have points (x,y,z) for bridge deck. There is some change in project (concrete is prestressed) and now I must add levels on every point of surface (bridge deck). In middle of deck I must add 9 cm, and if I go close to the piers in get lower. Example (0 +1 +2 +3 +4 +5 +6 +7 +8 +9 +8 +7 +6 +5 +4 +3 +2 +1 0). Zero is on piers, 9 cm is added on middle of deck where prestressed in biggest. Is there LISP that can save me time, that can manipulate with surface on way that I want?

Tnx

First off would expect the pre-stress to be a parabolic shape not linear but just take simple maths formula to work out new x,y,z maybe use excel to work out new z's copy a new column using concatenate "Point x,y,z" copy the column directly to the command line.
