Detailed Description

Defines a connected set of faces.

The following image depicts an example of a shell:

Shell

Direct children of shell are faces which must be connected with each other (i.e. have common edges) and consistently oriented (i.e. each common edge must be forward in one face and reversed in the other).

Although the data model can describe a non-manifold topology (i.e. a common edge shared by more than two faces), it is strongly not recommended to construct such.

Shell bounding a solid must be closed. A shell not belonging to a solid may have free edges (i.e. shared by one face only).

Member Function Documentation

Append()

bool cadex::ModelData_Shell::Append

(

const ModelData_Face &

theFace

)

Adds a face to the shell.

There is no requirement that theFace must be connected to faces already added to the shell. However all the faces in the shell must be connected and properly oriented after adding all faces.

Returns false if theFace is null and true otherwise.
