MASS

2: entity, use_sym

M

mass

if use_sym is not 0, includes symmetry images

UNITMASS

1: entity

M for a point

ML^-1 for a curve

ML^-2 for a surface

ML^-3 for a solid

unit weight property of entity

HYDRO

6: sp.gr., Zcg, sink, trim, heel, index

various, depending on index

fixed-position hydrostatics based on the visible contours

index is 1 to 29; selects one of 29 results, e.g. index = 6 for displacement volume;

index = 15 for wetted surface

SURFCURV

5: magnet, hi_side_u, hi_side_v, kind, angle

L^-1 for kind = 0 or 2; L^-2 for kind = 1

Surface curvature

kind = 0, normal curvature

kind = 1, Gaussian curvature

kind = 2, mean curvature

CURVINT

3: curve, t, real

L times units of real

integral of real times ds along curve

ds is the element of arc length along the curve

t is a Variable

real is a Formula descended from t

SURFINT

4: surface, u, v, real

L^2 times units of real

integral of real times dA over surface

dA is the element of area on the surface

u and v are Variables

real is a Formula descended from u and v
