Automate Ship Stability

Here's the thing:

I'd really like to get a precise calculation of ships GZ using acad and excel since its installed on most systems.

I never wrote a lisp and this one might be a huge combination of lisp.

1-So I start from a the ship hull in 3d with initial draught set and angle 0°.

2-Then I need to divide the distance between de draught and baseline in an odd number of planes.

3-Then I need to calculate the area of the planes (or whatever kind of lines I might use, right now I have a lisp for closed PL's so using that is thumbs up.) and extract that data in excel.

I hope i Haven't lost you yet.

4-But it gets better, after you extracted that data in excel what you need to do is rotate the hull model 5°,

5- and calculate volume at the initial draught and compare it to base model and adjust draught' until volume is egal to initial draught volume.

6-Then divide the distance between the new draught and baseline in a odd number of planes.

7-Calculate area of those planes and extract in excel.

8-Back to 4

total number of times: 36

up to 180° in 5° increments....
