This inheritance list is sorted roughly, but not completely, alphabetically:

[detail level 12]

CMatrix
CSimpleArg::Opt	An option (named or positional)
CPatch	A class representing a Bézier patch
CPatchBuilder	A builder class for constructing Bézier patches from a mesh
CPatchConstructor	Abstract base class for patch constructors
CExtraordinaryPatchConstructor	Patch constructor for extraordinary patches. See PatchConstructor
CNGonPatchConstructor	Patch constructor for n-gon patches. See PatchConstructor
CPolarPatchConstructor	Patch constructor for polar patches. See PatchConstructor
CRegularPatchConstructor	Patch constructor for regular patches. See PatchConstructor
CT0PatchConstructor	Patch constructor for T0 patches. See PatchConstructor
CT1PatchConstructor	Patch constructor for T1 patches. See PatchConstructor
CT2PatchConstructor	Patch constructor for T2 patches. See PatchConstructor
CTwoTrianglesTwoQuadsPatchConstructor	Patch constructor for patches consisting of two triangles and two quads. Designed for patch next to a polar patch. See PatchConstructor
CPatchConstructorPool	Pool PnS patch types represented as PatchConstructor subclasses. Each subclass corresponds to a specific PnS patch type. There are two types of patch constructors: vertex-based and face-based. A vertex-based patch constructor checks if a vertex and its neighborhood matches a PnS patch type. A face-based patch constructor checks if a face and its neighborhood matches a PnS patch type
CPatchConsumer
CBVWriter
CEvaluatedMeshWriter
CIGSWriter
CSTEPWriter
CPnSPatch	Represents a polynomial patch in Bernstein–Bézier form
CPnSpline	Represents a PnSpline(Polyhedral net Spline) composed of piecwise polynomial patches PnSPatch
CPnSplineImpl
CSimpleArg	A simple command-line argument parser
CVertexMapping	Represents a mapping from vertices in subdivided mesh to vertices in the original mesh. Each mapping consists of a list of vertex indices in the original and corresponding weights. The vertex in the subdivided mesh is represented as a weighted combination of the vertices in the original mesh. This class contains arithmetic operators to facilitate combining mappings during subdivision
