BRep solid entity definition. A manifold solid B-rep is a finite, arcwise connected volume bounded by one or more surfaces, each of which is a connected, oriented, finite, closed 2-manifold. There is no restriction on the genus of the volume, nor on the number of voids within the volume.

The Boundary Representation (B-rep) of a manifold solid utilizes a graph of edges and vertices embedded in a connected, oriented, finite, closed two manifold surface. The embedded graph divides the surface into arcwise connected areas known as faces. The edges and vertices, therefore, form the boundaries of the face and the domain of a face does not include its boundaries. The embedded graph may be disconnected and may be a pseudo graph. The graph is labeled; that is, each entity in the graph has a unique identity. The geometric surface definition used to specify the geometry of a face shall be 2-manifold embeddable in the plane within the domain of the face. In other words, it shall be connected, oriented, finite, non-self-intersecting, and of surface genus 0.

Faces do not intersect except along their boundaries. Each edge along the boundary of a face is shared by at most one other face in the assemblage. The assemblage of edges in the B-rep do not intersect except at their boundaries (i.e., vertices). The geometry curve definition used to specify the geometry of an edge shall be arcwise connected and shall not self intersect or overlap within the domain of the edge. The geometry of an edge shall be consistent with the geometry of the faces of which it forms a partial bound. The geometry used to define a vertex shall be consistent with the geometry of the faces and edges of which it forms a partial bound.

A B-rep is represented by one or more closed shells which shall be disjoint. One shell, the outer, shall completely enclose all the other shells and no other shell may enclose a shell.

Public class Mesh

A triangle mesh is a type of polygon mesh in computer graphics. It comprises a set of triangles (typically in three dimensions) that are connected by their common edges or corners.

Depending on the types of vertices and triangles, it can assume different configurations, see table below.

Public class MultilineText Multiline Text entity.
Public class NurbsBase
Public class OrdinateDim Ordinate dimension entity.

The ordinate dimension consists of an X or Y value with a leader line.

It measures the perpendicular distance from an origin point (called the datum) to a defining point (such as a hole in a part).

X-datum ordinate dimensions measure the distance of the defining point from the datum along the X axis.

Y-datum ordinate dimensions measure the distance of the defining point from the datum along the Y axis.

If the dimension is vertical it measures the X value. Otherwise, it measures the Y value.
