Cross Sections

crossSecCrvs( Shl, Srf, Resolution)

It returns a group of cross section curves between Shl and Srf. The group contains closed and open curves. areaOfCrossSec is used to find the area of these curves. The area of cross section is a sum of all the the closed curves in this group. Some closed curves may represent holes/pockets etc in the shell. The area of those is to be substracted from the whole. So to differentiate the holes from the other whole area, the curves are colored. Curves in Blue color have a positive area. Curves in Red color represent the holes and have a negative area. All other curves which do not effect the area are in default color.

Returns

<group> group of cross section curves

Shl

<Shell | Surface | Prim | Frature> The object whose cross section is to be found. All volume primitives and mechanical features will generate a geometric description as a shell, and thus can be used in this operation. Surfaces are internally converted to shells. Shells can also be constructed explicitly if desired.

Srf

<Surface> A flat surface used as a cutting plane

Resolution(0.025)

<number> Optional numerical resolution to use in the calculation.

areaOfCrossSec( Shl, Srf, Resolution)

Returns

<number> area of cross section. See also crossSecCrvs

Shl

<Shell | Surface | Prim | Frature> The object whose cross sectional area is to be found.

Srf

<Surface> A flat surface used as a cutting plane

Resolution(0.025)

<number> Optional numerical resolution to use in the calculation.

areaOfCrv( Crv)

This can be used to find the area of an individual curve returned from crossSecCrvs

Returns

<number> area of a closed planar curve.

Crv

<Curve> The curve whose area is to be found.
